Lipomas are beneficial mesenchimal neoplasms. Angiolipom is a common lipom variant characterized by the adipositive cells as well as the main veins. Atypical lipomatous tumors are local aggressive mesenchimal neoplasms that are characterized by atypical stromal cells. They often appear deeply localized in the lower limbs. There are four histological subtypes. Until now, atypical lipomatosis tumors with any angiolipom or angiolipom-like fields with malignant transformation have not been identified in British literature. We presented here an atypical lipomatosis tumor phenomenon similar to angiolipom, which consists of focal cytological atypics, maturity fat cells and accompanying common head vessels. In large diameter and profoundly inserted angiolipom-like lesions, it is necessary to do a careful examination to eliminate liposarcoma. Liposarcoma can rarely be metastatic or metastatic. It should be discussed whether our phenomenon is a variant of liposarcoma or whether angiolipom is a malignant transformation.
