[Giant parotid pleomorphic adenoma--presentation of a case and review of the literature].

This is a case presentation of a 51-year-old patient, with a giant parotid tumor on the right side (18 x 11 cm on the longer, cranio-caudal axis, 950 g), with an extremely slow evolution, since 1978. There are no clinical signs of malignancy within the tumor. A total parotidectomy with conservation of the facial nerve and a cervico-facial plasty were performed. The pathological result indicated a pleomorphic adenoma with central malignant foci. Such cases are rare in the literature, approximately 12 similar cases.
