A case report of granular cell ameloblastoma associated with aneurysmal bone cyst like features.

Granular cell ameloblastoma is a rare variant of ameloblastoma, which is histopathologically characterized by the presence of large eosinophilic granular cells within the ameloblastic follicle. Its accurate preoperative diagnosis is based upon clinical, radiological, and incisional biopsy findings. This article reports a case of granular cell ameloblastoma in a 65-year-old female, which on incisional biopsy showed the features suggestive of aneurysmal bone cyst. Furthermore, the influence of macroscopic presentation of the current lesion on its accurate preoperative incisional biopsy diagnosis is discussed in detail.
