Introduction: Warthin’s tumor is the second most common benign neoplasm of the salivary glands, which affects almost exclusively the parotid gland, and its diagnosis and treatment have been extensively discussed. Objective: To assess aspects of the diagnosis and treatment of patients with Warthin’s tumor. Methods: A retrospective clinical study was conducted with a group of 32 patients with histopathologic diagnosis of Warthin’s tumor of the parotid gland, who were operated in the Otolaryngology Service at HSPE between January 1982 and June 2002. Information was collected on age, sex, symptoms, supplementary examinations, location, size, surgical technique, complications and evolution. Results: The cases were more prevalent among men and in the 7th decade of life. The most frequent clinical presentation was a nodule on the parotid gland, and the average delay between the start of symptoms and seeking medical advice was 31.3 months. An ultrasound examination was performed in 10 patients, and the most frequent finding was a cystic nodule. Fine-needle aspiration biopsy cytology was performed in 14 patients and had 85.7% sensitivity for Warthin’s tumor, giving a diagnosis of Warthin’s tumor in 12 cases. The most frequently used treatment was superficial parotidectomy, with only 2 cases of enucleation. The most frequent complications were paresis (12.5%) and facial paralysis (9.4%), followed by Frey’s syndrome (6.2%). Conclusions: Warthin’s tumor is a neoplasm with a primarily clinical diagnosis, which needs to be confirmed by a histopathologic examination of a parotidectomy specimen. This procedure is curative in most cases.
