Lipomatous Hemangiopericytoma: A Rare variant of Hemangiopericytoma

Abstract

Introduction: Lipomatous hemangiopericytoma is a very rare variant of hemangiopericytoma. Histologically it is characterized by the presence of hemangiopericytomatous vasculature and mature adipocytes. Case report: We describe a Lipomatous hemangiopericytoma that arose retroperitoneally in a 45 year old male. Conclusion: It is important to differentiate these benign neoplasm’s from other tumors showing a dual adipocytic and spindle-cell composition that have a more aggressive outcome
