Su Yeon Kim, Hyunsik Bae, H. S. Kim
Abstract
Dedifferentiated liposarcoma (DDL), exhibiting divergent heterologous differentiation, is a rare entity with a variable reported incidence. These tumors typically arise in the retroperitoneum, often attaining substantial size and presenting at advanced stages, thereby posing significant diagnostic and therapeutic challenges. We report a rare case of recurrent DDL with dual heterologous differentiation—osteosarcomatous and chondrosarcomatous—in an elderly male initially presenting with symptoms m
