Idiopathic pleomorphic midfacial granuloma (Stewart's type)

Idiopathic mid-facial granuloma is an unusual highly destructive disease which was virtually unknown prior to 1955. Great confusion exists, due in large part to the terminology applied to this entity as well as the clinical similarity of the process to other destructive mid-facial lesions. A classical case of idiopathic mid-facial granuloma of Stewart's type is presented, with characteristic lesions limited to the mid-face. Definitive histopathological features consist of pleomorphic inflammatory granulation tissue with patchy necrosis and no system lesions or neoplasia in the autopsy tissues.
