Clinical Discussion

Angiolipoma is a common benign entity that typically appears in late adolescence and early adulthood with a male predominance, though they can occur in both men and women of all ages. Clinically, these lesions typically present as small subcutaneous nodules which are painful to the touch. Angiolipomas most commonly occur on the extremities, with the second most common location being the trunk. Histologically, they consist of mature, benign adipocytes and small calibre benign vessels; the proportion of fat to vessel tissue can vary from lesion to lesion. Angiolipomas are benign lesions, and are not thought to recur or undergo malignant transformation. Treatment with excision can be considered due to pain, cosmesis, and to rule out other more worrisome processes.
