An aggressive peripheral giant cell granuloma in a child.

An 11-year-old boy was evaluated for a maxillary lesion that had been increasing in size over a six-month period. Intraoral examination revealed a firm ulcerated lesion on the maxillary posterior alveolus, which was displacing teeth. The lesion was painful and easily bled during mastication. An incisional biopsy of the lesion resulted in the diagnosis of peripheral giant cell granuloma. The patient was taken to the operating room for excision of the lesion and extraction of involved teeth. The patient was followed for a period of six months with no recurrence.
