There are two types of angiolipoma, namely noninfiltrating and infiltrating. Noninfiltrating angiolipoma is seen in young individuals and presents as painful, soft, and cutaneous nodules. Occasional compression of nerve fibers that accompany the vascular channels could be demonstrated. Treatment is a mere enucleation. Infiltrating angiolipoma is rather rare. Only 34 cases have been reported in the English literature. Though histologically benign, the tumor can infiltrate bony, muscular, neural, and fibrocollagenous tissues to cause unusual symptoms and signs and can clinically simulate malignant neoplasms. Wide excision including the normal tissue surrounding the tumor is mandatory. We reported our cases with review of literatures and discussed the clinical and pathologiocal features of this entity.
