Giant cell tumor of the mandible.

ABSTRACT

Giant cell tumor (GCT) of bone is a distinctive neoplasm characterized by abundance of multinucleated giant cells scattered throughout the stroma of mononuclear cells. Its importance lies in recognizing and differentiating the characteristic histology, which at times may mimic several other bone tumors and endocrine disorders ranging from locally aggressive giant cell granulomas to hyperparathyroidism to malignant tumors. The jaw bones account for less than 1% of the lesion. Ina literature search, we found only five cases of GCT of jaw bones based on the new criteria. We present a rare case of GCT of the mandible which occurred in a 12-year-old female.
