AIM To report a case of a non-neoplastic variant of calcifying odontogenic cyst (COC) with the lining epithelium showing ameloblastomatous proliferation and capsule exhibiting features of a cholesterol granuloma. The importance of delineating this histologic variant from unicystic ameloblastoma and the formation of cholesterol granuloma in this variant is discussed. BACKGROUND Calcifying odon...

AIM To report a clinical case of unicystic ameloblastoma previously misdiagnosed as radicular cyst. SUMMARY A 49-year-old white male was referred to a private practitioner complaining of an asymptomatic bony hard swelling of the left posterior mandible. The patient's dental history indicated that his left mandibular first molar had been extracted approximately 10 years previously. At that tim...

Introduction. We report a rare case of unicystic ameloblastoma (UA) of mandible which showed multilocular radiolucency on the left side of mandible on radiographic examination which is very unusual, and the majority of the cases of UAs till date has been reported of unilocular radiolucency. On histopathological examination, an odontogenic cystic lining that proliferates that intraluminally rese...

Spindle-cell differentiation in ameloblastic carcinoma is a rare event. Although reported by many authors, it was first described as a separate entity in 1999 by Slater under the heading "low-grade spindle-cell ameloblastic carcinoma." Here, we report a case of low-grade spindle-cell ameloblastic carcinoma arising in pre-existing unicystic ameloblastoma.The patient, a 60-year-old Indian woman, ...

The aim of this work was to describe a case of unicystic ameloblastoma located in the left posterior mandibular body and angle of a 14-year-old Caucasian male. The tumour was described at clinical and histological level; moreover, its histopathological phenotype was depicted. Finally, the problems of differential diagnosis with odontogenic or congenital cyst and the most appropriate therapeutic...

A 46-year-old man was referred to our hospital for treatment, complaining of swelling on the right mandibular molar region. Radiographic examination revealed a well defined multilocular radiolucent lesion with root resorption of right lower anteriors and molars. Following biopsy, a diagnosis of unicystic ameloblastoma of mural type was made and hemimandibulectomy was performed under general ane...

Results: Of the 70 cases, 35 (50%) occurred in males and 35 (50%) in females. Young adults were most affected by tumors. Fifty-six (80%) of all tumor cases occurred in the jaw. The main histological subtype seen was unicystic ameloblastoma, which occurred in 35 cases. The majority of the tumors [n=57 (81.4%)] were treated with radical surgery. The differences in clinical aspects and anatomical ...
