Dysplastic Papilliferous Basaloid Ameloblastoma: Report of a Case

Abstract

Papilliferous ameloblastoma is an uncommon histologic variant of ameloblastoma. About five cases have been reported in the English literature till date. All five showed squamous differentiation with keratin formation and were diagnosed as papilliferous keratoameloblastoma. The present lesion
shows basaloid differentiation and mild dysplasia in addition to papilliferous projections, thus termed dysplastic papilliferous basaloid  ameloblastoma.  Ameloblastoma, the most common odostoma has not ceased to intrigue pathologists with its diverse histomorphological patterns. Therefore, we present this uncommon lesion in a 50 year old man with right mandibular swelling.

Key words: Papilliferous, Basaloid, Ameloblastoma, Dysplastic, Nonhealing socket.
