An infrequent histopathological subtype of ameloblastoma: Adenoid granular cell ameloblastoma with dentinoid.
Adenoid ameloblastoma with dentinoid is a rare odontogenic tumor. Granular cell ameloblastoma also is a less common histological subtype of ameloblastoma. In this report, the patient was a 31-year-old male. The lesion was located in the right mandible and was unicystic with well-defined borders. The tumor tissue was showing a combination of follicular, plexiform, and desmoplastic patterns of ameloblastoma with wide areas of granular cells, fibrous stroma, glandular pattern, and dentinoid calcified. Very few cases of distinct forms of ameloblastoma that show the formation of dentinoid has been reported. However, there are no cases of adenoid granular cell ameloblastoma with dentinoid reported.
