Computer assisted histomorphologic comparision and the expression of AgNORs in the central and peripheral giant cell lesions of the oral cavity and giant cell tumor of the long bone.

Objective: Computer-assisted image analysis was attempted to ascertain, if any of the previously described histologic features along with argyrophilic nucleolar organizer regions (AgNORs) could be used to determine the aggressiveness of the central giant cell granuloma of the jaws (CGCG), peripheral giant cell granuloma of the oral cavity (PGCG) and giant cell tumor of the long bones (GCT).

Study Design: The study consisted of 20 cases of CGCG, 20 cases of PGCG and 5 cases of GCT. The histological features included were number of giant cells, number of nuclei in each giant cell, number of blood vessels, fractional surface area (FSA) and relative size index (RSI) of giant cells.

Primary melanoma of oral mucosa: A case report and review of literature.

Primary oral melanoma is a rare neoplasm of melanocytic origin, accounting for 0.5% of all oral malignancies. The "chameleonic" presentation of a mainly asymptomatic condition, rarity of this lesion, poor prognosis, and the necessity of a highly specialized treatment are factors that should be seriously considered by the involved health provider.

Adenomatoid hyperplasia of lower lip.

Adenomatoid hyperplasia (AH) is an uncommon, non-neoplastic swelling on the palate caused due to hyperplasia of the mucinous acini. The lesion clinically presents as a sessile tumor-like nodule resembling pleomorphic adenoma. Histopathologic findings include lobules of enlarged mucinous acini which are filled with secretory granules.

An unusual combination of idiopathic generalized short-root anomaly associated with microdontia, taurodontia, multiple dens invaginatus, obliterated pulp chambers and infected cyst: a case report.

Generalized diminished root formation is a rare condition leading to early loss of teeth. This report describes an unusual case of generalized short roots associated with microdontia, taurodontism of posterior teeth, and multiple dens invaginatus along with short stature in a 20-year-old man, who had lost several teeth because of spontaneous exfoliation.
