[Venous malformations of the parotid in adults. Report of two cases and review of the literature].

Parotid vascular malformation in the adult is a very rare and benign tumor; only 47 cases were described in the world literature. This vascular malformation, mostly of venous origin is, on the opposite of the clinical, histological and evolution features of parotid hemangiomas in children, which are more frequent. Some clinical and radiological elements are pathognomonic allowing preoperative diagnosis. We present 2 cases of intraparotid venous malformation in adults, and based on an exhaustive study of the world literature discuss frequency, diagnosis and treatment of this disease.
