Granular cell ameloblastoma (GCA) is a well recognized variant of follicular ameloblastoma with extensive granular cell change. In contrast, plexiform granular cell odontogenic tumor (PGCOT) is a rare and recently described lesion characterized histologically by a monophasic plexiform pattern of granular cells. In this paper, two cases of an unusual granular cell odontogenic tumor exhibiting co...

Renaming of the Odontogenic Keratocyst as the Keratocystic Odontogenic Tumor by the World Health Organization (WHO) is based on the aggressive nature of this lesion. Satellite cysts founded in the walls of the original cysts may give rise to a new lesion formation. The aim of this retrospecitve study was to identify the existence of specific features according incidence of satellite cysts and t...

objective: the ortho keratinized odontogenic cyst (ooc) is a rare lesion originates from dental lamina and clinically, it may be mistaken for many other odontogenic cysts and tumors. microscopically, it should be distinguished from kcot because of differences in biologic behavior and histologic features.   case: an interesting case of ooc arising in the edentulous mandibular right first premola...

ameloblastomas are tumors of odontogenic epithelial origin. the term unicystic ameloblastoma is used to describe cystic lesions with clinico-radiographic features resembling an odontogenic cyst, but histologically showing the presence of ameloblastomatous epithelium lining part of the cyst cavity. a large majority of lesions are found in the mandible, and usually cause a painless swelling of th...

statement of problem: the aggressive nature and high recurrence rate of odontogenic keratocysts (okcs) may be due to unknown factors inherent in the epithelium or because of enzymatic activity in the fibrous wall. bcl-2 protein is characterized by its ability to inhibit apoptosis. purpose: the aim of the present study was to analyze the expression of bcl-2 protein in okcs and to compare it with...

Odontogenic keratocysts are benign lesions of the maxillomandibular region with high growth potential resulting in huge bone destruction. The presence of multiple Odontogenic keratocysts can be associated with the Gorlin-Goltz syndrome. There are two accepted theories of their origin: remnants of dental lamina and proliferation of cells from the basal layer of oral epithelium into the mandible ...

BACKGROUND Primordial Odontogenic Tumor (POT) is a recently described odontogenic tumor characterized by a variably cellular loose fibrous tissue with areas similar to the dental papilla, covered by cuboidal to columnar epithelium that resembles the internal epithelium of the enamel organ, surrounded at least partly by a delicate fibrous capsule. The purpose of this study was to investigate the...

Multiple calcified hyperplastic dental follicles (MCHDF) are an extremely rare condition which has been categorized as a separate pathological entity very recently. It was initially described by Sandler et al. Gardner and Radden proposed this as a separate pathological entity. This disease is characterized by multiple unerupted teeth with abundant calcifications and rests of odontogenic epithel...

This was a retrospective study of odontogenic keratocysts in people from the Singapore-Malaysian region. The purpose of this study was to present the clinicopathologic features of odontogenic keratocysts in the Oriental population and to compare these data with those from other reported studies. Biopsy records from 1981 to 1992 of 61 cases of odontogenic keratocysts from patients in Malaysia an...
