Focal Cemento-osseous Dysplasia Expansive Type: A Case Report

Abstract

Focal cemento-osseous dysplasia (FCOD) is a subgroup of benign fibro osseous lesions, which occur in a single site of tooth-bearing areas of the jaws. It is usually asymptomatic and noticed accidentally through routine radiological examinations. This article is a case report of a 37-years-old female patient with a complaint of swelling of mandibular anterior region for the past 3 months. Extraoral examination revealed a diffuse swelling in the right lower anterior segment. On radiographic examination, a mixed radiolucent/radio-opaque lesion with ginger root-like opacities and a radiolucent rim, but with extension into the basal bone was noticed in the symphysis region. Based on radiographic appearance, a provisional diagnosis of Cementoblastoma / Calcifying Epithelial Odontogenic Tumour was given. An incisional biopsy was submitted to the department of Oral Pathology for histopathological reporting and the case was finally reported as FCOD. This case report is being presented with interest to focus on FCOD Expansive type. Cemento-Osseous Dysplasia (COD) can be divided into focal and florid types, familial and non-familial types, and an expansive type. The expansive COD is a rare entity presenting as a single expanding lesion in a non-familial capacity.
