Lesão de células gigantes periférica em paciente periodontal - relato de caso

Peripheral giant cells lesion is a disease that involves soft tissues, from the gingival margin or alveolar ridge. There is an unknown etiology, although it is considered a reactive lesion in response to chronic local irritation such as subgingival calculus and overhanging restorations. Clinically, the peripheral giant cells lesion presents as reddish to purplish, nodular, pediculate or sessile elevations, with a smooth or lobulate surface, which might be ulcerated or not, with slow evolution and limited growth. The treatment involves surgical removal of the lesion while recurrence is found in about 10% of the cases. The objective of this report is to describe a recurrent case of peripheral giant cell lesion associated with periodontitis. Key words: Giant cell lesion. Reaction lesions.
