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.

Abstract

Periferal ameloblastoma, diş dokusu kaynaklı, klasik ameloblastomaya benzeyen, nispeten yaygın olmayan bir tümör olup dişi oluşturan yapıların bir parçası olarak epitel ve/veya mezenşimal elementlerden çoğalır. Alveolar mukoza veya gingiva olarak adlandırılan ağız boşluğunun yumuşak dokusundan köken alabilir. Histopatholojik sekiller arasında en yaygını, pleksiform ve foliküler tarafından takip edilen acanthomatousdur. Granüler hücre ameloblastoma'nın bir zamanlar ameloblastoma'nın en agressif formu olduğu düşünülürdü, ancak son dönemlerde yapılan çalışmalara göre önceki inanışların bir mit oluğu görüşü yaygınlaşmaya başladı. Kırk dört yaşındaki bir kadında, histopatolojik olarak granüler hücre, pleksiform, acanthomatous, foliküler ve desmoplastik ameloblastomanın kombinlenmiş özelliğini gösteren bir periferal ameloblastoma olgusu bildirilmiştir.
