title: Malignant parotid tumors. Diagnostic considerations and therapeutic suggestions.
abstract: This paper presents our experience of the problem of diagnosis and surgical treatment of malignant parotid tumors, based on a retrospective evaluation of a series of 478 parotid tumors, of which 100 were malignant. Out of 75 primaris malignant tumors of epithelial origin, 35 belonged to the "epidermoid" group (adenocarcinomas, undifferentiated carcinomas, malignant mixed tumors, squamous cell carcinoma), 20 were mucoepidermoid carcinomas, 15 adenoid cystic carcinomas and 5 were acinic cell carcinoma. Altogether, 58.7% of the treated patients do not at the moment present evidence of disease; 33.3% are dead from the disease or are alive with active disease; 5.3% are dead from other causes and 2.7% are lost to follow-up. Underlining the importance of histologic examination of the swelling by intraoperative biopsy, the authors propose a diagnostic and therapeutic protocol.
