Kompleks Histolojik Paternler İçeren Periferal Ameloblastoma

Abstract

Peripheral ameloblastoma is a relatively uncommon neoplasm of odontogenic origin histologically resembles the classic ameloblastoma and derived from epithelial and/or mesenchymal elements being part of the tooth forming apparatus. It can be originated in the soft tissue of oral cavity namely alveolar mucosa or gingiva. Among histopathological pattern the most common is acanthomatous followed by plexiform and follicular. Granular cell ameloblastoma once considered as the most aggressive variant of ameloblastoma but according to the recent studies it is believed that the earlier belief was a myth. We report a case of peripheral ameloblastoma in a 44 year old lady, histopathologicaly showing combined features of granular cell, plexiform, acanthomatous, follicular and desmoplastic ameloblastoma. As per our best knowledge this is the first case of its type.

An Insight into the Histopathology of Oral Neoplasms with Basaloid Morphology and a Working Classification

“…The diagnosis of IOBCC solely on histopathological grounds, however, is not easy, due to their histological resemblance with peripheral ameloblastoma (PA). 11,12 The differentiation between IOBCC and PA is of utmost importance since the former is malignant.…”
