Central Calcifying Cystic Odontogenic Tumor of Mandible - A Case Report.

The calcifying cystic odontogenic tumor (CCOT) is a rare benign odontogenic cystic neoplasm. The terminological conundrum regarding its categorization as a cyst or a tumor has been resolved after the latest WHO classification (2005) that has labelled it as a tumor. The diversity in its morphological patterns, clinical behaviour, histologic complexity and prognosis has led to the practise of multiple management strategies with variable results. This report describes a case of CCOT presenting as a large cystic lesion in theanterior mandible that was managed by enucleation and curettage with a postoperative one year recurrence free follow up. A brief review of literature pertaining to various management strategies of CCOT in comparison with dentinogenic ghost cell tumor (DGCT) is also presented.

Florid Osseous Dysplasia.

Florid osseous dysplasia is a rare non-neoplastic and asymptomatic bone disorder involving the jaws. It is commonly seen in elderly females. Discovered on routine radiographic examination it manifests as radiopacities involving multiple quadrants. Microscopically, the lesion shows a fibroblastic proliferation along with irregular trabeculae of woven bone and cementum like material. Here with presenting two such interesting cases of this rare entity presenting in a family and associated with multiple impacted teeth.

Histochemical and polarization microscopic study of two cases of vegetable/pulse granuloma.

Vegetable granuloma (VG) or pulse granuloma (PG) results from the implantation of food particles of plant or vegetable origin. It is usually seen in the periapical or in the sulcus areas. These lesions have been described as a distinct entity and classified into central and peripheral lesions according to the location. Central lesions are asymptomatic, whereas peripheral lesions present as painless sub-mucosal swellings. Many authors have postulated that food particles in VG or PG get implanted and are rapidly digested, and sometimes partly get altered by host responses. The cellulose part of plant foods being indigestible persists in the form of hyaline material, whereas the starch matter gets digested. This cellulose moiety invokes chronic granulomatous response.
