Ameloblastoma of Anterior Mandible: Case Report

Abstract

Churchill gave the term “Ameloblastoma”. According to Robinson it is a “usually unicentric, nonfunctional, intermittent in growth, anatomically benign and clinically persistent tumor”. It is a benign odontogenic tumor originating from residual epithelium of the tooth germ, epithelium of odontogenic cysts stratified squamous epithelium and epithelium of the enamel organ. Histopathologically, it occurs in six patterns: plexiform, follicular, acanthomatous, granular cell, basal cell, and desmoplastic type.  It is the second most common odontogenic neoplasm. It accounts for 11% of all odontogenic tumors and is characterized by slow growth and local infiltration into the adjacent tissues. About 80 % of ameloblastomas occur in the mandible, it frequently involves molar and mandibular angle (70 %), premolar (20 %), and rarely anterior region (10 %). Itis seen in adults in the third to fifth decade of life. Here, we are presenting a case of a 46-year-old male presented with a swelling in right anterior mandible diagnosed with plexiform ameloblastoma.
