Abstract

Dedifferentiated liposarcoma shows a wide morphological spectrum. We present a case of dedifferentiated liposarcoma of the spermatic cord in a 66-year-old male that was initially misinterpreted as pseudosarcomatous proliferative funiculitis with mesothelial proliferation.

Keywords: mesothelial structures; paratesticular liposarcoma; pseudosarcomatous proliferative funiculitis.
