A case of relatively large lipoma of the right neck is reported and thirty-three cases of lipomas treated in our department from 1965 to 1986 are reviewed.<BR>A 64-year-old man was admitted to our department complaining of a right neck swelling. The preoperative diagnosis was lipoma based on clinical findings as well as the image findings of CT scan and echogram. The tumor was excised through a cervical skin incision under general anesthesia. It lied between the platysma and the superficial layer of the cervical facia. The enucleated yellow and soft specimen was 12×7×6.5cm in size, and covered with a thin fibrous capsule. The histopathological diagnosis was lipoma. The prognosis has been good for about one year. From our statistical study the distribution by site of 33 lipomas is as follows: eleven cases in the check, five in the lower lip, five in the tongue, three in the submandibular region, two in the gingiva, the floor of the mouth, the soft palate, the preauricular portion each other and one in the neck.Males are more affected than females.76% of the patients are over 40 years of age.
