We describe a rare case of dedifferentiated liposarcoma with features resembling chondroblastic osteosarcoma in the dedifferentiated component. The tumor was removed from the left thigh in a 78‐year‐old male. It consisted of a well‐differentiated liposarcoma and an anaplastic component that contained numerous osteoid and cartilaginous tissues surrounded by high‐grade spindle cell sarcoma. To our knowledge, only two cases similar to the divergent chondroblastic osteosarcomatous dedifferentiation of this disease have been reported in the literature.
