Lipoma is a benign tumor involving overgrowth of mature adipose tissue which can occur in anywhere adipose tissue is present Lipoma is extremely rare but relatively easy to discover through imaging diagnosis by CT and ultrasound. Preliminary checks of their location in relation to the submandibular region are vequired preoperativery. CT-sialography is also in dispensable. The two cases presented here describe tumors that developed in the sublingual and submandibular space, and were suspected to be lipoma according to the results of imaging diagnosis. CT-sialography was effective for evaluating the relationship between the tumors and Wharton's duct. In two cases, the tumors were removed at operation and were confirmed histopathologically to be lipoma.
