Granuloma reparador de c茅lulas gigantes: relato de cinco casos Giant cell reparative granuloma: report of five cases
O granuloma reparador de c茅lulas gigantes 茅 les茫o 贸ssea rara, correspondendo a cerca de 7% de todos os tumores 贸sseos benignos da mand铆bula, com maior incid锚ncia no sexo feminino. Embora seja considerada resposta a um trauma, este antecedente nem sempre est谩 presente. O aspecto radiol贸gico caracter铆stico 茅 de les茫o l铆tica, uni ou multiloculada, com afilamento da cortical, podendo apresentar calcifica莽玫es no seu interior. Neste trabalho relatamos os aspectos cl铆nicos e radiol贸gicos de cinco casos de granuloma reparador de c茅lulas gigantes envolvendo a mand铆bula e o maxilar, e as principais caracter铆sticas que permitem o diagn贸stico diferencial com outras les玫es fibro-贸sseas que acometem a face.<br>Giant cell reparative granuloma is an uncommon bone lesion accounting for slightly less than 7% of all benign tumors of the jaw and affecting predominantly females. It probably represents a reparative reaction to a traumatic injury, although history of trauma is not always confirmed. The characteristic radiological feature is a uni- or multilocular lytic bone defect eroding the bone cortical and occasionally presenting with calcifications within the lesion. We report the most important clinical and radiological features observed in five patients with giant cell reparative granuloma involving the mandible and the maxillae and discuss the main aspects for the differential diagnosis with other fibro-osseous lesions that affect the facial bones
