[Warthin's tumor: clinical aspects and a cytological study using fine-needle puncture-aspiration in 16 cases]

The clinical and fine-needle cytologic findings of 16 Warthin's tumors (papillary cystadenoma lymphomatosum) are presented. They were studied during a period of 38 months, between February 1987 and April 1990. A preoperative diagnosis of "Warthin's tumor" was made in 13 cases (80%); 3 cases were diagnosed as non neoplastic benign lesions (2 retention cysts and 1 chronic sialoadenitis). 10 cases were surgically excised and preoperative diagnosis was histologically confirmed. We compare the cytologic findings of our cases with the literature ones.
