Cellular angiolipoma of the breast

Cellular angiolipomas are benign fatty tumors that occur as multiple subcutaneous nodules on the extremities and trunks of young adults. Although clinically benign, they may occasionally mimic Kaposi's sarcoma or angiosarcoma histologically. We report the first case of cellular angiolipoma occurring in the subcutaneous tissue of the breast, a rare but well-recognized site of benign and malignant vascular tumors.
