Angiolipoma-like Atypical Lipomatous Tumor/Welldifferentiated Liposarcoma
Journal Title: Journal of Academic Research in Medicine - Year 2020, Vol 10, Issue 2
Abstract
Lipomas are benign mesenchymal neoplasms. Angiolipoma is a variant of ordinary lipomas, characterized by adipocytic cells as well as capillary vascular clusters. Atypical lipomatous tumors are local aggressive mesenchymal neoplasms which include atypical stromal cells. They frequently arise in the deep thigh of the lower extremity. They have four histologic subtypes. So far, there aren’t any case of angiolipoma with malignant transformation or atypical lipomatous tumor with angiolipoma-like areas in the English literature. Here we presented a case of atypical lipomatous tumor which was quite like angiolipoma. It was composed of mature fat with focal cytologic atypia and also accompanying diffuse capillary vessels. If there is a large-diameter and deeply located angiolipoma-like lesion, careful examination is required to rule out a liposarcoma. Liposarcomas may be rarely dedifferentiate or metastatic. It is not possible to verify that if the case is a variant of liposarcoma or it is a malignant transformation of angiolipoma.
