A case of infiltrating angiolipoma of the right lower extremity is reported. Angiolipomas are benign neoplasms of adipose tissue with a rich vascular component and are classified as either infiltrating or noninfiltrating. Noninfiltrating angiolipomas are seen in young individuals, present as painful, soft, subcutaneous nodules and are treated by enucleation. Infiltrating angiolipoma is a rare neoplasm with only 23 previously reported cases. These lesions are usually unencapsulated or rarely partially encapsulated and tend to infiltrate bony, neural, muscular, and fibrocollagenous tissue. Treatment of infiltrating angiolipomas is aimed at wide excision with radiotherapy indicated for cases of recurrence.
