ABSTRACT
Malignant mesenchymoma is an interesting but very rare tumor in which malignant differentiation has occurred twice or more. We report a case of retroperitoneal malignant mesenchymoma consisting of osteosarcoma, leiomyosarcoma, liposarcoma and fibrosarcoma. Abdominal CT showed a large retroperitoneal mass with two separate and distinct parts, namely an area of prominent calcification and one of clearly enhancing solid components. The mass contained histologically distinct tumorous components with no histologic admixure at the interfaces. The densely calcified nodule corresponded to osteosarcoma, and the noncalcified clearly enhancing nodules to leiomyosarcoma, liposarcoma and fibrosarcoma.
