A case of Warthin's tumor arising in an area except the parotid gland which is rare is reported. A 66-year-old man was admitted to the hospital because of a tumor in the neck which had been felt since 2 years before admission. CT of the neck revealed a small hen's egg sized circular tumor showing isodensity in the right superior lateral side of the neck. With a diagnosis of benign cervical tumor, the tumor was enucleated. The tumor was present in the underside of the sternocleidomastoid muscle, and covered with thin fibrous capsula. It was easily freed and no communication with the parotid gland, submandibular gland, nerves, and vessels. The enucleated tumor was 4.5 × 2.7 × 1.7cm in size and elastic hard, and the section was solid with scattered small cysts. Histologically, epithelial cells with papillary growth formed cystadenoma and hyperplasia of lymphatic tissues with embryo center in stroma. The epithelial cells showed two layers, presenting typical pictures of Warthin's tumor. An etiologic hypothesis has been widely accepted that Warthin's tumor originates from the ectopic salivary gland tissues in lymph nodes. It is thought that the tumor in this case might arise from lymph node, because no correlation with the parotid and submandibular glands were demonstrated during the operation.
