Diagnostic Approach to Synovial Sarcoma of the Head and Neck Illustrated by Two Cases Arising in the Face and Oral Cavity.

In the head and neck region, synovial sarcomas (SS) are rare tumours. We describe the diagnostic approach to SS based on two cases which developed in a 26-year-old male in the face and in a 53-year-old female on the alveolar mucosa of the upper jaw. The demographic profile of the patients was compatible with the literature.

Benign Fibrous Histiocytomas of the Oral Mucosa: Report on Three Cases and Review of the Literature.

Benign fibrous histiocytomas (BFH) of the skin are common lesions, although they only rarely involve the oral mucosa. This article presents 3 additional cases of BFH of the oral mucosa, with a review of previously published cases. Although a malignant variant of BFH also exists, the present review focuses only on benign lesions.

Descriptive study of 896 Oral squamous cell carcinomas from the only University based Oral Pathology Diagnostic Service in Sri Lanka.

Background: The main objective of this study was to describe selected clinico-pathological characteristics of Oral Squamous Cell Carcinoma (OSCC) in Sri-Lanka.

Materials & Methods: The study sample comprised of eight hundred and ninety six biopsies diagnosed as OSCC. The clinical and histopathological features were analyzed using the Chi-square test.

A Peripheral Dentinogenic Ghost Cell Tumor With Immunohistochemical Investigations and a Literature Review-Based Clinicopathological Comparison Between Peripheral and Central Variants.

The aim of the study was to present a peripheral dentinogenic ghost cell tumor (DGCT) and to describe clinicopathological differences between peripheral and central variants of the tumor using a selected literature review. The case report is based on a swelling present on the alveolar ridge of a 74-year-old edentulous denture wearer. The lesion was diagnosed as a peripheral DGCT after excluding the presence of a central lesion.

A literature review on oral basaloid squamous cell carcinomas, with special emphasis on etiology.

In the recent years, basaloid squamous cell carcinomas (BSCCs) have gained attention because of (1) observation of a relative increase in the number of tumors arising particularly in head and neck sites, (2) identification of human papillomavirus (HPV) in BSCCs arising predominantly in the oropharynx, and (3) controversies that exist regarding the biological aggressiveness of the tumor. The objective of the present review was to address the issues mentioned above by focusing primarily on oral BSCCs, using literature that has been published in the English language up to 2013. According to the literature review, oral BSCCs were found to be relatively more common in elderly patients with a mean age of 64 years.
