Warthin's Tumor : Treatment
Complete surgical excision with adequate surgical margins is usually curative. Local recurrence may follow an incomplete excision of Warthin’s tumor. Malignant transformation is seen in less than 0.1% cases and can occur in either epithelial component (squamous cell carcinoma, oncocytic carcinoma, adenocarcinoma NOS, mucoepidermoid carcinoma) or lymphoid component (Non-Hodgkin’s lymphoma). The image shows papillary structures lined by bi-layered oncocytic epithelium and enclosing scant amount of lymphocytic infiltrate.
