We describe a rare case of Warthin's tumor with formation of a large cyst. This case was classified as Seifert's metaplastic type (Type IV) histopathologically. A brief discussion is included. A 61-year-old woman was referred to our hospital because of a swelling on the left side of the neck on August 26, 2003. She had noticed the mass for 2 years, and a fine-needle aspiration biopsy was performed at another hospital on August 12, 2003. However, a definitive histopathological diagnosis was not obtained, and her dentist referred her to our hospital. Physical examination revealed a painless, elastic hard, mobile mass measuring 40mm in diameter, in the inferior pole of the parotid gland, anterior to the sternocleidomastoid muscle. There was no evidence of associated lymphadenopathy. No uptake of<SUP>99m</SUP>TcO<SUB>4</SUB><SUP>-</SUP>was detected in the lesion. MRI revealed a mass with medium T<SUB>1</SUB>signal intensity and low T<SUB>2</SUB>signal intensity in the left side of the neck, involving the superficial lobe of the parotid gland. Clinically, a benign parotid gland tumor was diagnosed, and a superficial parotidectomy was performed under general anesthesia on October 14, 2003. The excised tumor was diagnosed as Warthin's tumor with formation of a large cyst. The postoperative course was uneventful.
