Ameloblastomas of jaws are benign odontogenic tumours with four clinical variants being solid multicystic type, unicystic type, extra osseous type and desmoplastic type. Unicystic ameloblastoma accounts for only 13% of all the known cases in the scientific literature. Follicular and plexiform patterns are the commonly seen histopathological patterns in unicystic ameloblastoma. Though rare in itself, presence of granular cells along with acanthomatous changes occurring in unicystic ameloblastoma is a rare phenomenon. We present a rare case report of unicystic ameloblastoma of right mandible with an unusual histopathology. It exhibited both luminal and mural types as well as both acanthomatous and granular cell changes found together. As occurrence of unicystic ameloblastoma of jaws with such varied histopathology is rare, their course, clinical outcome, prognosis and recurrence rate are not clear. Documentation of more such cases in literature may make pathogenesis and nature of these lesions more insightful.
