ABSTRACT
Background: Oral mucocele are common non neoplastic lesions of the oral cavity that develop either as a result of damage to the duct or obstruction to the duct of minor salivary gland. Histopathologically oral mucoceles are divided into two categories: Extravasation mucoceles often seen in young individuals, the lower lip being the classic location. The second category includes retention mucoceles, which occurs most often in older patients usually located in the floor of the mouth and the inside the cheek. Objectives: This study aims to describe the demographic and histological characteristics of Oral mucocele along with com- parative study between Extravasation mucocele and Retention Mucocele. Method: A total of 32 cases of mucocele diagnosed in the Department of the Pathology, between 2012 and 2019 were re- viewed. The clinical data were recorded and histopathologic diagnosis was made. The study variables included were age, gen- der, type, site, color, etiology, symptoms and dimension of the lesion. Results: A total of 32 cases of oral mucocele cases were studied corresponding to a M:Fratio of 1.13:1. Peak incidence occurred in third decade followed by equally in the first and second decades of life. Extravasation Mucocele was the clinical diagnosis in 59.4% and Retention Mucocele in 40.6%. Most lesions were located in the lower lip (59.3%). Conclusion: This study provides an important insight into demographic and histological profile of oral mucocele lesion. It was concluded that oral mucocele predominantly presented in two histological forms, Extravasation Mucocele which was more common than other lesser common form Retention Mucocele. Although these lesion are easily diagnosed on the basis of clini- cal presentation but sometimes these swelling can mimic other benign mucosal lesion of these region, hence histopathologi- cal examination must be done in order to rule out these lesion and also to note any variation from its normal morphological findings.
