Histology

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.
