Infiltrating angiolipoma of the cheek

Angiolipoma, spindle cell lipoma, myelolipoma, chondrolipoma and myxolipoma are histological variants of lipomas arising from fat tissue. Although angiolipoma is the most common tumour in the trunk and forearm, it occurs infrequently in the head and neck region. In this report we present a case of angiolipoma occurring in the buccal mucosa of a 33-year-old man. The patient had noticed a painless mass in his buccal mucosa for 2 months. The surgically removed tumour, measuring 4 × 4 cm in diameter was histologically evaluated. The tumour was composed of proliferations of mature fat cells and connective tissue containing many small blood vessels, which were evenly distributed.
