Lipoma of the parotid gland, which consists of mature adipose cells, is a rare benign tumor observed in about 1 % of tumors of the parotid gland.On the other hand, infiltration of the parotid gland by adipose cells has been described by various terms since Gilman and co-workers reported "fatty infiltration of the parotid gland" in 1956.This condition has been called "fatty infiltration, " "sialosis" or "lipomatosis" by different authors because the definition of such lesions has not yet established.We recently treated a patient suffering from lipoma of the parotid gland accompanied by lipomatosis of the parotid gland. This 35-year-old male patient first visited our department in May of 1984 with the chief complaint of a painless tumor in the left parotid area.Preoperative examinations showed a lipoma accompanied by lipomatosis of the parotid gland by CT scanning. The patient received superficial parotidectomy under general anesthesia, and no recurrence has been observed 6 months after surgery.We discuss the difference between lipoma of the parotid gland and infiltration of the parotid gland by adipose cells, which we call "lipomatosis" and the usefulness of CT scanning in the diagnosis of such lesions.
