Abstract
- Cellular angiolipomas are fatty tumors that occur as multiple painful subcutaneous nodules on the trunk and arms of young male adults. Although clinically benign, they may occasionally mimic Kaposi's sarcoma or angiosarcoma histiogically. Encapsulation, septation, small size, endothelial cells without atypia, intravascular microthrombi, and clinical presentation in healthy individuals help to exclude a malignant diagnosis. We report a case of cellular angiolipoma on the extremities and trunk of a 19-year-old man. Histopathological findings showed well-circumscribed tumor composed of vascular endothelial cells and spindle cells forming vascular spaces intermingled with scattered adipocytes. Immunohistochemical studies demonstrated reactivities for endothelial and muscle markers, highlighting the obscured angiomatous component in the cellular areas of the tumor.
