Primary subcutaneous mixed-type liposarcoma of the thigh showing three simultaneous dedifferentiations: Report of an unusual case

Abstract

Liposarcoma most commonly occurs in deep soft tissues of the limb and the retroperitoneum; however, its occurrence in the subcutaneous tissue is rare. Mixed-type liposarcoma (MTL) is the rarest subtype. We herein describe a unique case of MTL with three simultaneous dedifferentiations occurring in subcutaneous tissue of left thigh in a 45-year-old male. We briefly review the pertinent literature and report this case because of extreme rarity.
