Necrosis of a Warthin's tumor following fine needle aspiration.

Abstract

Fine needle aspiration (FNA) biopsy of a parotid mass demonstrated features diagnostic of a Warthin's tumor. Resection of the mass six weeks later yielded a necrotic nodule lacking distinguishing characteristics. This case illustrates infarction of the target lesion, a rare complication of FNA biopsy of salivary gland neoplasms. Correlation of the histology with the cytology will prevent diagnostic difficulties in such instances.
