Why the study?
Dedifferentiated liposarcoma with divergent dedifferentiation is uncommonly reported, frequently occurs in the retroperitoneum, grows to large size, presents at late stages, and can have a poor clinical outcome.
Reports a rare case of recurrent dedifferentiated liposarcoma with dual heterologous differentiation.
May prompt thorough histologic review in recurrent retroperitoneal liposarcoma; leaves open optimal management strategies.
Dedifferentiated liposarcoma (DDL) with divergent dedifferentiation is uncommonly reported with variable incidences. Liposarcomas, particularly those manifesting dedifferentiation, occur in the retroperitoneum. They grow into large size, present at very late stages, and can have a poor clinical outcome. Here we present a rare case of recurrent dedifferentiated liposarcoma with dual heterologous differentiation with osteosarcoma and Chondrosarcoma in an elderly male who had initially presented wi
