Lipoma is well-circumscribed, non-epitherial benign neoplasm. It may arise in almost any part of human body where adipose tissue is present. Although the lipoma is a rather common tissue tumor, it is rarely seen in the oral cavity. The cheek is the most common site, followed by the tongue and oral floor of the mouth. Lip is a relatively rare site in oral cavity. The following two cases of lipoma in the lip are reported here. Additionally a review of the available literature of intraoral lipoma from the years 1935 to 1990 disclosed 179 cases in Japanese literature. Case 1 : A woman, aged 53, presented a mass in the left lower lip. The tumor was excised. It measured 23 mm by 29 mm by 14 mm, 1.91 g by weight. Case 2 : A man, aged 62, presented a mass in the right lower lip. The tumor was excised. It measured 23 mm by 18 mm by 18 mm, 2.45 g by weight. Although uncommon lipoma occurs most frequently in the cheek, tongue and oral floor of the mouth, there is no sex or age predilection. Pathological diagnosis of the two cases was simple lipoma and progress of the two has shown no sign of recurrence.
