title: [Role of echography in the preoperative evaluation of palpebral basal cell epithelioma].
abstract: The palpebral region is one of the commonest locations for basal cell epitheliomas of the face. The tumor can spread to both orbital cavity and its structures. Ten patients with basal cell epitheliomas of the face were studied with US to investigate its diagnostic accuracy; US findings were compared with CT ones. In all cases US allowed a complete study of both morphology and structure of the tumor; it precisely defined the status of the superficial structures of the orbital cavity (cornea and anterior chamber of the eye), differentiating between tumor contiguity, compression and infiltration. US seems therefore essential to the preoperative assessment of tumor spread and during the follow-up of patients with palpebral basaliomas.
