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 muco-epidermoid 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.
