Liposarcoma: A Pictorial and Literature Review

Abstract

According to some clinical trials and epidemiologic studies, WDL is the most common LS (40%), followed by myxoid LS (20%), DDLS, pleomorphic LS (5%), and, last, mixed-type LS. [3,6,8] There are crucial differences among each subtype regarding presentation, treatment, and prognosis. WDL WDL is the most common subtype, representing the 40-50% of all LSs. WDL is a low-grade tumor due to their highly lipomatous content. Histologically, they are composed of variable size mature adipocytes, with scattered lipoblast and large fibrous stroma, and in some cases, they may present sclerosing and inflammatory components.
