A Rare Simultaneous Occurrence of Odontogenic Keratocyst and Unicystic Ameloblastoma in Mandible: A Case Report

摘要

Odontogenic Keratocyst (OKC) and Ameloblastomas are slow growing benign odontogenic lesions that primarily occur in the molar region of the mandible. Clinically and radiographically both ameloblastoma, especially the Unicystic ameloblastoma and OKC are indistinguishable due to the similar location of occurrence and the age of patients. It is very rare for these lesions to arise simultaneously in a patient's jaw. The co-occurrence of Ameloblastomas with odontogenic cysts or other odontogenic lesions (histologically in a single lesion)have already been described as combined or hybrid lesions. There are very few reported cases in the English literature for simultaneous occurrence of Unicystic Ameloblastoma and OKC as completely distinct lesions. Here we present such a rare case of the simultaneous occurrence of OKC and ameloblastoma in the posterior region of the mandible of a 22-year-old male in close relation.
