Histogenetic concepts, terminology and categorization of biphasic tumours of the oral and maxillofacial region.
A biphasic tumour is a truly histological term that refers to neoplastic tissue which is characterized by two different cellular elements. Several histogenetic theories have been proposed for the aetiogenesis of the biphasic tumours. Literatures have been published on the individual lesions, which have described their biphasic nature but, biphasic tumours have not been categorized singly . Categorizing biphasic tumours is not likely to highlight diagnostic standards, but it may sensitize the therapeutic planning and post operative monitoring. This review article focuses on the histogenetic concepts of biphasic tumours, and the histopathological description of the lesions that are suggested to be biphasic tumours.
