Lesão de células gigantes periférica (granuloma de células gigantes periférico): relato de um caso

Resumo (EN)

Peripheral giant-cell lesion is an infrequent reactive exophytic lesion of the oral cavity. Its causes are not known, although it is thought that it may be due to trauma, tooth extraction, calculus, chronic infections, impacted food. May present itself as nodular lesions, predominantly bluish red with a smooth shiny surface. They are variable in size, rarely exceeding 2 cm in diameter, and are generally soft or rubbery to touch. They are basically asymptomatic, unless they interfere with occlusion, in which case they may ulcerate and become infected. They are more frequent in women than in men, and affect largely the lower jaw in the premolar region. The final diagnosis should be confirmed on the basis of histological appearance, basically characterized by the presence of multinucleate giant cells in a stroma showing varying degrees of inflammation and vascularization. Treatment is usually by surgical excision and elimination of possible irritant factors, with recurrence being infrequent. The present study report a case of peripheral giant-cell lesion.
