Mucosal keratocyst of buccal mucosa: A rare entity.

The odontogenic keratocyst (OKC) is a developmental odontogenic cyst that is important due to its specific histopathologic features and clinical behavior. It is well known that the OKC arises from cell rests of the dental lamina. This cyst is important as it shows a different growth mechanism and biologic behavior from other common odontogenic cysts.

Prevalence of Carcinomatous Foci in Oral Leukoplakia: A Clinicopathologic Study of 546 Indian Samples.

Introduction: Oral Leukoplakia (OL), the most common potentially malignant disorder, is diagnosed clinically on the basis of exclusion of other lesions. In a country like India, where prevalence of oral cancer is very high, the issue of carcinomatous foci within OL at the time of initial diagnosis of leukoplakia has never been addressed before.

Aim: To estimate the prevalence and risk factors for epithelial dysplasia as well as carcinoma within OL lesions at the time of initial clinical presentation in an Indian population with high prevalence of tobacco use.
