Extremities, trunk, even on the face.
Clinical featuresThis section has been translated automatically.
Sharply defined, shifting, relatively coarse, subcutaneous node. Frequently pressure-treated. Angiolipomas occur in > 50% of patients in the majority.
HistologyThis section has been translated automatically.
Circumscribed lobular tumor node made of mature adipocytes and provided with a delicate connective tissue capsule. A second tissue component is abundantly formed, often thrombosed vessels. A protruding or dominant vascular component is called a cell-rich angiolipoma (cellular angiolipoma). The cell-rich angiolipoma can occur together with the conventional lipoma. It shows reactivity for CD31 and CD34.
