Lost salt technique for severely resorbed alveolar ridges: An innovative approach
Himanshi Aggarwal, Sunit K Jurel, Raghuwar D Singh, Pooran Chand, Pradeep Kumar
July-September 2012, 3(3):352-355

The success of a complete denture relies on the principles of retention, stability and support. The prosthodontist skill lies in applying these principles efficiently in critical situations. Severely resorbed maxillary edentulous ridges that are narrow and constricted with increased inter ridge space provide decreased support, retention and stability. The consequent weight of the processed denture only compromises them further. This article describes a case report of an edentulous patient with resorbed ridges where a simplified technique of fabricating a hollow maxillary complete denture using lost salt technique was used for preservation of denture bearing areas. The hollowing of the denture reduces the weight of the denture, thereby enhancing stability and retention, reducing the further resorption of the jaws.

Dentigerous cysts are the most common type of developmental odontogenic cysts arising from the crowns of impacted, embedded, or unerupted teeth. They constitute about 20% of all epithelium-lined cysts of the jaws. The teeth involved most often are mandibular third molar and maxillary canines. About 70% of dentigerous cysts occur in the mandible and 30% in the maxilla. Dentigerous cysts associated with ectopic teeth within the maxillary sinus are fairly rare, and only 20 cases had been reported in Medline since 1980. In the present paper, we report an additional case of dentigerous cysts associated with ectopic third molar in the right maxillary sinus. Also, pathogenesis of ectopic tooth, role of advanced imaging, differential diagnosis, and management are discussed.

Rashes can occur in any part of the body. But rash which appears on face has got both psychological and cosmetic effect on the patient. Rashes on face can sometimes be very challenging to physicians and dermatologists and those associated with oral manifestations pose a challenge to dentists. Butterfly rash is a red flat facial rash involving the malar region bilaterally and the bridge of the nose. The presence of a butterfly rash is generally a sign of lupus erythematosus (LE), but it can also include a plethora of conditions. The case presented here is of a female with butterfly rash along with typical bright red discoloration of gingiva. The clinical, histopathological and biochemical investigations suggested the presence of rosacea.

Botryoid odontogenic cyst (BOC) is considered to be a polycystic variant of the lateral periodontal cyst (LPC) as the specimen resembled a cluster of grapes. It is a non-inflammatory odontogenic cyst. The BOCs can be unicystic or multicystic. These cysts have potential to extend in the bone and become multilocular and they have a high recurrence rate. Till now, only 73 cases of BOC have been reported. The pathogenesis of BOC is still debatable. We review different pathogenesis proposed for BOC and discuss a rare case of BOC developing from lining of an abnormally large LPC which showed aggressive behaviour in terms of growth and size.

Reactive lesions of oral cavity: A survey of 100 cases in Eluru, West Godavari district
Bina Kashyap, P Sridhar Reddy, P Nalini
July-September 2012, 3(3):294-297
DOI
:10.4103/0976-237X.103621
PMID
:23293484
Aim:
Reactive lesions of the oral cavity are associated with injuries of soft tissue and have high prevalence rates and different involvement patterns in different parts of the world. This study reviews the pathogenesis and analyzes demographic data, histopathological features and compares the clinico-pathologic profiles of the diseases to those previously reported.
Materials and Methods:
Patient records of the Department of Oral Pathology during one and half year period were reviewed for diagnosis of oral connective tissue reactive hyperplastic lesion. Data including the area involved and the type of lesion were collected and analyzed using descriptive statistical methods and ANOVA test.
Results:
100 cases (mean age 36 years, male:female ratio 1:2) matched study criterion. The most common affected site was mandibular anterior region and buccal mucosa and the most common lesion was pyogenic granuloma and focal fibrous hyperplasia. All the lesions were more common in the mandible than in the maxilla. PGCG was seen to be equally distributed in males and females.
Conclusion:
Reactive hyperplastic lesions of the oral connective tissue are more common in females and the majority of the lesions occur in gingiva. This study supports previous assertions that PG and FFH may occur on any oral mucosal site with special preference for the mandibular anterior gingiva and buccal mucosa while PGCG and POF occur exclusively on the mandibular gingiva.

PMID
:23293502
A 13-year-old female patient reported with the chief complaint of irregular front teeth. She had a skeletal Class III and Angle's Class I malocclusion with hyperdivergent growth pattern and bilateral impaction of maxillary canines. Surgical exposure of the impacted teeth and orthodontic alignment was planned. The surgical exposure was done by a minimally invasive modified window technique. Orthodontic treatment of impacted canines without causing significant morbidity to the adjacent teeth and periodontium is a challenge. The bilaterally impacted maxillary canines were successfully aligned and leveled. The depth of the gingival sulcus and clinical crown heights of disimpacted teeth were normal post-treatment and after 1 year of retention.

PMID
:23293494
Introduction:
Every orthodontist at some point in his clinical practice has faced the dilemma of how 'best' to manage a mild to moderate Class II malocclusion.
Aims and Objectives:
To demonstrate the efficacy of Forsus™ Fatigue Resistant Device in the management of Class II malocclusion.
Materials and Method:
A patient having Class II division 1 malocclusion with functional jaw retrusion was treated using MBT 0.022" prescription and Forsus FRD appliance. Pre- and post-treatment photographs and lateral cephalograms were taken. Cephalometric analysis was done, and results were superimposed.
Result:
7-8 months of Forsus wear obtained stable and successful results with improvement in facial profile, skeletal jaw relationship, and mild increase in IMPA.
Discussion and Conclusion:
Greater forward displacement of the mandible was the predominant factor for successful treatment Class II patient. Forsus gives good results for class II management, and it would be wise to consider treating such cases by non-extraction approach rather than contemplating extractions.

: An
in vitro
study
Garima Agarwal, Gayathri G Vemanaradhya, Dhoom S Mehta
July-September 2012, 3(3):256-261
DOI
:10.4103/0976-237X.103614
PMID
:23293477
Background:
Propolis as a natural remedy has maintained its popularity over long periods of time. The aim of this study was to determine the chemical composition in terms of total phenolic compounds and flavonoids present in Chinese propolis and to carry out an
in vitro
evaluation of its antimicrobial activity and the minimal inhibitory concentrations for
Porphyromonas gingivalis
(Pg) and
Aggregatibacter actinomycetemcomitans
(Aa).
Materials and Methods:
From the ethanolic extract of propolis (EEP), total phenol content was determined by the Folin-Ciocalteau method, flavones and flavonols by the modified aluminum chloride colorimetric method, and flavanones by the 2.4-dinitrophenylhydrazine (2,4-DNP) method. Agar well diffusion assay was used to evaluate the antimicrobial potential of propolis against Pg and Aa. The minimum inhibitory concentration of propolis against the two bacteria was determined using serial tube dilution technique.
Results:
The total concentration of phenol in the EEP was 19.44%, flavones and flavonols 2.616%, and flavanones 16.176%. The inhibitory zone depicting antimicrobial activity ranged from 18 to 25 mm for Pg and from 12 to 14 mm for Aa. The concentration range of Chinese propolis that is sensitive to inhibit the growth of Pg was 0.1-0.0125 μg/ml and for Aa it was 0.1-0.025 μg/ml.
Conclusion:
These data suggest that Chinese propolis has potent antimicrobial activity against the two periodontopathogens, suggesting its possible use as a natural alternative to the widely used synthetic antibiotics for periodontal therapy.

Odontomas are benign odontogenic tumors composed of enamel, dentine, and cementum and pulp tissue. They are usually clinically asymptomatic, but often associated with tooth eruption disturbances. The present study reports an unusual case of eleven odontomas in the left lateral incisor-canine region of lower jaw. A 26 years old female presented to the department of orthodontics and dentofacial orthopedics in H.P. Govt. Dental College and Hospital Shimla for the treatment of misaligned teeth. Clinical examination revealed that the lower left lateral incisor was missing. Patient was advised for radiographs, which revealed a mixed radiopaque lesion associated to impacted lower left canine. The histological report in this case indicated a compound odontoma.

Vinod B Mathew, Koppolu Madhusudhana, Nuvulla Sivakumar, Thangala Venugopal, Redderu K Reddy
July-September 2012, 3(3):262-264
DOI
:10.4103/0976-237X.103615
PMID
:23293478
Context:
Antisepsis achieved through appropriate use of irrigants is essential for endodontic success. Identification of newer anti-bacterial agents gives alternatives to clean the canal as eradication of the infection prior to obturation does affect prognosis.
Objective:
Comparison of the anti-bacterial action of 3.8% silver diamine fluoride and 2% chlorhexidine gluconate against
Enterococcus faecalis
in root canals.
Materials and
Methods:
Forty-four single-rooted teeth were decoronated, and the root section was enlarged with peeso-reamer (No: 3) to standardize length and diameter. The samples were then autoclaved and divided into two study groups and two control groups.
Enterococcus faecalis
ATCC 29212 was inoculated into all test samples for 72 hours. The samples were enlarged with peeso-reamer (No: 5) after placement of respective medicament for 24 hours. Shavings were collected and inoculated on Brain Heart Infusion agar for 24 hrs to measure the colony forming units.
Results:
Both 3.8% silver diamine fluoride and 2% chlorhexidine showed a superior capacity to sterilize the root canals than control groups.
Conclusion:
The use of silver diamine fluoride as an endodontic irrigant is feasible as it can effectively remove the microbes present in the canal and circumpulpal dentin.

July-September 2012, 3(3):282-287
DOI
:10.4103/0976-237X.103619
PMID
:23293482
Aim:
The purpose of this study was to evaluate and compare the tensile bond strength and microleakage of Fuji IX GP, Fuji II LC, and compoglass and to compare bond strength with degree of microleakage exhibited by the same materials.
Materials and Methods:
Occlusal surfaces of 96 noncarious primary teeth were ground perpendicular to long axis of the tooth. Preparations were distributed into three groups consisting of Fuji IX GP, Fuji II LC and Compoglass. Specimens were tested for tensile bond strength by mounting them on Instron Universal Testing Machine. Ninety-six primary molars were treated with Fuji IX GP, Fuji II LC, and compoglass on box-only prepared proximal surface. Samples were thermocycled, stained with dye, sectioned, and scored for microleakage under stereomicroscope. ANOVA and Bonferrani correction test were done for comparisons. Pearson Chi-square test and regression analysis were done to assess the association between the parameters.
Results:
Compoglass showed highest tensile strength and Fuji II LC showed least microleakage. There was a significant difference between the three groups in tensile strength and microleakage levels. The correlation between tensile strength and microleakage level in each group showed that there was a significant negative correlation only in Group 3.
Conclusion:
Fuji II LC and compoglass can be advocated in primary teeth because of their superior physical properties when compared with Fuji IX GP.

Comparative study to evaluate shear bond strength of RMGIC to composite resin using different adhesive systems
Manoj G Chandak, Navdheeraj Pattanaik, Ayan Das
July-September 2012, 3(3):252-255
DOI
:10.4103/0976-237X.103613
PMID
:23293476
Aim:
The aim of the study is to compare and evaluate the role of new dental adhesives to bond composite to the resinmodified glass inomer cement (RMGIC).
Materials and Methods:
Thirty specimens were prepared on acrylic blocks, with wells prepared in it by drilling holes, to retain the RMGIC. The specimens were randomly divided into three groups of ten specimens each. In Group a thin layer of selfetch adhesive (3M ESPE) was applied between the RMGIC and the composite resin FILTEK P60 (3M SPE). In Group II, total etch adhesive (Adeper Scotch bond 2, 3M ESPE) was applied, and in Group III, there was no application of any adhesive between RMGIC and the composite resin. After curing all the specimens, the shear bond strength was measured using an Instron universal testing machine.
Results:
The results were drawn and tabulated using ANOVA-fishers and Dunnet D statistical tests.The maximum shear bond strength values were recorded in Group I specimens with self-etch adhesive showing a mean value of 2.74 when compared to the Group II adhesive (Total etch) showing a mean shear strength of value 1.89, where no adhesive was used, showed a minimum mean shear bond strength of 1.42. There was a great and significant difference between Group I and Group II (
P
value 0.05) whereas, both Group I and Group II showed a vast and significant difference from Group III (
P
value = 0-001).
Conclusion:
Hence, this present study concludes that application of self-etch adhesive (3M ESPE, U.S.A) in between RMGIC and composite resin increases the shear bond strength between RMGIC and the resin composites, as compared to the total-etch type adhesive (Adeper Scotch bond 2,3M ESPE, U.S.A) as well as without application of the adhesive agent.

Liquid supported denture-management of flabby ridges
Pranav V Mody, Girish Kumar, Manish Kumar, Brijesh Shetty
July-September 2012, 3(3):323-325

The ideal properties of a denture are adequate rigidity on polished surface to bear masticatory forces and at the same time, flexibility and softness on the tissue surface for proper and even distribution of masticatory forces. The problem with conventional denture is rigidity of tissue surface; leads to uneven distribution of load. This drawback even worsens in the case of flabby, atrophic and unemployed ridges with excessive bone resorption.The liquid supported denture allows continued adaptation and eliminates the disadvantages of denture designs based on the application of temporary tissue conditioners or soft liners.

PMID
:23293479
Background:
The inability of the normal adult population to perform adequate tooth brushing has led to the search for chemotherapeutic agents in order to improve plaque control. This 6 month, single center, randomized controlled clinical trial was conducted to assess the clinical and microbiological effects of a dentifrice containing only amine fluoride (AF) as the active ingredient on gingivitis.
Materials and Methods:
Ninety subjects diagnosed with chronic generalized gingivitis were selected and randomly divided in three groups: Group 1 - placebo toothpaste, Group 2 - AF containing toothpaste, and Group 3 - triclosan containing toothpaste with polymer and fluoride. Clinical evaluation was undertaken using the gingival index of Loe and Silness and the plaque index and microbiological counts were assessed at baseline, 6 weeks, 12 weeks, and 24 weeks. A subjective evaluation was also undertaken by a questionnaire.
Results:
AF containing toothpaste showed significant improvement in gingival and plaque index scores as well as microbiologic counts compared with placebo dentifrice. These improvements were comparable to triclosan containing toothpaste.
Conclusions:
AF containing toothpaste may be a useful formulation for chemical plaque control agent and improvement in plaque and gingival status and add to the list of various therapeutic agents used for maintenance of gingival health.

Osteosarcoma is the most common primary malignant mesenchymal tumor, accounting for approximately 20% of sarcomas, with 5% incidence in the jaws. They present various clinical and histological aspects as well as variable disease prognosis and outcome. About 50% of all osteosarcomas are osteoblastic, 25% fibroblastic, 25% chondroblastic. Metastasis of osteosarcoma in the oral cavity is rare, and very few cases have been described so far in the literature. This article presents a metastatic case of chondroblastic osteosarcoma in the mandibular right-attached gingiva arising from 4
th
rib. This case report further suggests that chondroblastic osteosarcoma has poor prognosis.

PMID
:23293480
Background:
Imbalances between the oxidant -antioxidant status have been implicated in the pathogenesis of several diseases, including cancer.
Aim:
The aim of this study was to evaluate the extent of lipid peroxidation and antioxidants in the venous blood samples of oral squamous cell carcinoma patients of different Clinicopathologic stages in comparison with the healthy controls.
Setting and Design:
A Case control study was designed in a hospital (Rajah Muthiah Dental College and Hospital, Annamalai University) based setting.
Materials and Methods:
Twenty new histopathologically proven oral carcinoma patients, and equal number of age, sex and habit matched healthy subjects were recruited for this study. Their blood samples were subjected to evaluation of Thiobarbituric Acid Reactive Substances (TBARS) and antioxidant enzymes, namely, superoxide dismutase (SOD), Catalase (CAT) reduced glutathione (GSH) and glutathione peroxidase (GPx) using spectrophotometric methods.
Statistical Analysis:
The data are expressed as mean±SD. The statistical comparisons were performed by independent Student's
t
-test and One Way ANOVA.
P
value <0.05 was considered statistically significant. Karl Pearson correlation was performed for the biochemical parameters within the group and between the groups. For statistically significant correlations, linear regression was performed.
Results:
Significant enhanced lipid peroxidation (
P
<0.001) with decrease in antioxidants (
P
<0.001) was observed in the venous blood of oral squamous cell carcinoma patients as compared with the healthy controls. Accordingly, significant (
P
<0.001) pattern of progression in TBARS levels was observed at various clinical stages of patients. (GSH) showed significant (
P
<0.01) negative correlation with TBARS and positive correlation (
P
<0.001) with SOD. On linear regression analysis, GSH showed significance for SOD (
P
<0.001), GPx, CAT and TBARS (
P
<0.01). It was also found that, 70% of variance in SOD can be attributed to the influence of GSH alone.
Conclusion:
Enhanced lipid peroxidation and compromised antioxidant defense in plasma indicate development of oxidative stress. Amongst the antioxidant enzymes, (GSH) appears to have a profound role in carcinogenesis.

Mahilan I Jeyavalan, M Narasimman, CJ Venkatakrishnan, M Philip Jacob
July-September 2012, 3(3):314-316

Restoration of a long span partially edentulous maxilla with tooth supported prosthesis is challenging because of inherent anatomic limitations and unfavourable biomechanics present after the loss of teeth. A tooth supported fixed-removable prosthesis is a treatment option for restoration of such long span partially edentulous maxillary arches. This prosthesis meets the requirements for esthetics, phonetics, comfort, and hygiene, as well as favourable biomechanical stress distribution to the remaining natural tooth abutments. This article presents a procedure for fabrication of a fixed-removable prosthesis that has cement-retained custom cast bar metal substructure and a ball attachment retained removable superstructure prosthesis.

A comparative evaluation of dentinal hypersensitivity and microleakage associated with composite restorations in cavities preconditioned with air abrasion - An
ex vivo
study
Ankit Arora, Shashi Rashmi Acharya, M Vidya Saraswathi, Padmaja Sharma
July-September 2012, 3(3):306-313
DOI
:10.4103/0976-237X.103624
PMID
:23293487
Background and Objective:
Enormous advances have been made in adhesives; however, the problem of post-operative sensitivity has dragged along. Enough literature exists on the effect of air abrasion over bond strength of composites. However, not much is reported on its relation with microleakage and post operative sensitivity. Therefore, the aim of the study was to compare and evaluate dentinal hypersensitivity and microleakage associated with composite restorations in cavities preconditioned with air abrasion.
Study Design:
Fifteen patients were selected for the study who had to undergo extractions of both maxillary first premolars. On each patient, occlusally placed Class V cavities were made using rotary burs on both the premolars. On the right side premolar, restoration was done using total etch technique. On the left side premolar, restoration was done in similar way after preconditioning of the cavity with air abrasion. Sensitivity levels were recorded on a modified visual analogue scale preoperatively and post operatively at 1 week and one month time period. Following extraction, dye penetration test was done and 1 sample each from one group was subjected to Scanning Electron Microscope for evaluation of tooth restoration interface.
Results:
Clinically significant difference was there in post operative sensitivity levels after one month between the two groups. Increase in sensitivity was less in teeth restored after preconditioning with air abrasion. Dye penetration was also less in teeth restored after preconditioning with air abrasion. However, penetration at the gingival wall was more than the occlusal wall in both the groups.
Conclusion:
The study consolidates the fact that microleakage and post operative sensitivity are linked directly. It also proves that air abrasion can help in reducing the post operative sensitivity to a level; however, a larger sample size would be needed to obtain more robust results with stronger validation.

Scheuthauer-Marie-Sainton syndrome also known as Cleidocranial dysplasia (CCD) is an autosomal dominant disorder characteristically presented with multiple supernumerary teeth; partial or complete absence of the clavicles; and open sagittal sutures and fontanelles. This condition was first reported by Meckel in 1760. There is also evidence that it existed in the prehistoric man. More than 1,000 cases have been reported in the medical literature regarding this syndrome. A case of a 35-year-male of CCD with multiple supernumerary teeth is being reported. The diagnostic and management aspects of this syndrome are discussed.

CBVT analysis of canal configuration of the mesio-buccal root of maxillary first permanent molar teeth: An
in vitro
study
R Pratima Shenoi, Hrishikesh M Ghule
July-September 2012, 3(3):277-281
DOI
:10.4103/0976-237X.103618
PMID
:23293481
Context:
For successful endodontic treatment, it's imperative to locate and obturate all root canals. As concluded by Ingle, the major cause for failure of root canal therapy is in ability to recognize all theexisting canals and subsequent failure in their obturation.
Aim:
To analyze the canal configuration of the mesio-buccal root of maxillary first permanent molar teeth.
Materials and Methods:
A total of 30 recently extracted human permanent maxillary first molars were collected and stored in a container with 5% Sodium Chloride solution for four days. Teeth with open apices, external resorption, improperly formed roots and teeth with previous restorations were excluded. Using the dental modeling wax, teeth were arranged in a 'U' shaped arch with roots embedded inside the wax and occlusal surface remaining free. 10 teeth were arranged in each arch and three such sample plates were prepared. Flat surface of the base encasing enabled the plate to be mounted on flat plastic bite plate. With bite plate roughly centered in the focal trough area Axial, Coronal and Sagittal section Cone-Beam Computed Tomography (CBCT) images were taken with Kodak 9000 Extra-oral Imaging System. Images displayed on a monitor were inspected by two endodontists using Kodak Dental Imaging Software 3D Module V2.2.
Statistical Analysis:
When the data was observed, it was found that 24 teeth out of total 30 teeth examined showed some variation (i.e. possible additional canal) along the length of the mesio-buccal root canal. Out of these 24 teeth, 13 showed presence of additional canal at coronal third, 7 showed presence of additional canal at middle third and four showed presence of additional canal in apical third level. Percentage analysis was done as there was no group comparison to be done.
Results:
Cone-Beam Volumetric Tomography (CBVT) evaluation positively identified the variations in mesio-buccal canal in 80% of samples. Out of these, 54.16% were in coronal 3
rd
, 29.16% in middle 3
rd
and 16.66% were in apical 3
rd
.
Conclusion:
Within the limitations of this study, it can be concluded that- (1) more than half of maxillary first molars have four canals and (2) most of the additional canals were located in the MBR and CBVT is a good diagnostic tool to help diagnose these additional canals. Further investigations using larger sample sizes would be helpful.

The phenomenon of buttressing bone formation is relatively uncommon in the alveolar bone, more so in the anterior maxilla. In our case, peripheral buttressing bone formation presented as an isolated hard gingival swelling with relation to 21 in a 14-year-old girl. Radiographic presentation was normal with no evidence of bone loss or altered bone density. Therefore explorative surgery was planned. Buttressing bone formation could be appreciated, which also was the cause for swelling clinically. Osteoplasty was done and bone graft placed in the defect. On a subsequent recall visit gingivoplasty was done to reduce gingival thickness to improve esthetics. We report the case for its unusual presentation, its management with follow-up.

Comparative evaluation of tensile bond strength of a polyvinyl acetate-based resilient liner following various denture base surface pre-treatment methods and immersion in artificial salivary medium: An
in vitro
study
Jacob M Philip, Dhanraj M Ganapathy, Padma Ariga
July-September 2012, 3(3):298-301
DOI
:10.4103/0976-237X.103622
PMID
:23293485
Background and Aim:
This study was formulated to evaluate and estimate the influence of various denture base resin surface pre-treatments (chemical and mechanical and combinations) upon tensile bond strength between a poly vinyl acetate-based denture liner and a denture base resin.
Materials and Methods:
A universal testing machine was used for determining the bond strength of the liner to surface pre-treated acrylic resin blocks. The data was analyzed by one-way analysis of variance and the
t
-test (α =.05).
Results:
This study infers that denture base surface pre-treatment can improve the adhesive tensile bond strength between the liner and denture base specimens. The results of this study infer that chemical, mechanical, and mechano-chemical pre-treatments will have different effects on the bond strength of the acrylic soft resilient liner to the denture base.
Conclusion:
Among the various methods of pre-treatment of denture base resins, it was inferred that the mechano-chemical pre-treatment method with air-borne particle abrasion followed by monomer application exhibited superior bond strength than other methods with the resilient liner. Hence, this method could be effectively used to improve bond strength between liner and denture base and thus could minimize delamination of liner from the denture base during function.

Juvenile ossifying fibroma is a rare fibro-osseous lesion containing variable amount of calcified masses, which resembles bone or cementum within a fibrocellular connective tissue stroma. It has variable clinical behavior, highly aggressive in nature including invasion and destruction of adjacent anatomic structures with a strong tendency to recur. We reported a 28-year-old female patient with a growth in the upper left vestibule region extending from canine to molar region with clinical, histopathological, and radiological features are presented. Surgical management was done, and regular follow-up was advised.

Malignant myoepithelioma is a rare salivary gland neoplasm, which accounts for less than 2% of all the salivary gland carcinomas. Majority of cases have been reported in parotid, and only 8 cases of involvement of the hard palate have been reported in the literature so far. Hereby, a case of painless, ulcerated palatal mass of 2 years of duration reported. A diagnosis of malignant plasmacytoid myoepithelioma was made with the aid of immunohistochemical analysis, and wide surgical excision was considered keeping in mind the biological behavior of the tumor.
