They typically have been described as possessing three biologic variants including solid, cystic (unicystic) and peripheral, of which about 13% to 21% of all cases are unicystic. Granular cell subtype is a rare variant especially when both the inner and peripheral layers of tumoral islands composed exclusively of eosinophilic granular cells. The purpose of this case report is to present a unique case of cystic ameloblastoma with an unusual radiographic and microscopic pattern affecting a 25-year-old female.
