title: [The malignant fibrous histiocytoma of bone (author's transl)].
abstract: The primary malignant fibrous histiocytoma of bone (Stout) is a rare and autonomous sarcoma of the bone which has to be separated from the osseous sarcoma and the osseous fibrosarcoma. The malignant histiocytoma is morphologically characterized by the storiform pattern of interlacing spindle cell bundles and functionally by the phagocytosis of lipids, glycogen, hemosiderin and hematoidin. Contrary to the osteosarcomas, the main age of osseous histiocytomas are the fifth and sixth decade. Location of predilection are the metaphyses of the long tubular bones. The X-rays show moth-eaten spongiolysis, endosteal erosion and perforation of the cortex. Early metastases in the lungs are frequent. The primary treatment is a surgical one. Case record of a typical malignant osseous histiocytoma from the proximal metaphysis of the left femur with metastases in the lung of a female child, aged 14 years.
