title: [The radiological manifestations of fibroxanthosarcomas (author's transl)].
abstract: The radiological findings in eight patients with fibroxanthosarcomas are described. In seven patients the primary tumour was in the soft tissues of the extremities or of the trunk. Infiltration of the primary tumour into a neighbouring bone, producing a "motheaten" appearance on the radiograph was seen in one case. A primary tumour in the mediastinum (one case cannot be distinguished radiologically from malignant lymphoma. Pulmonary metastases were found radiologically in five patients; in two they were solitary and in three patients there were multiple round foci measuring up to 8 cm. in diameter. Metastases in the lung hila and mediastinum were found only in the presence of pulmonary metastases (three cases). Pleural effusions developed in an advanced stage of the disease only (three cases). A solitary, purely osteolytic bone deposit was seen in two patients. Multiple metastases in the kidneys were hypo- or avascular, but some showed fine corkscrew vessels. On intravenous urography they could be demonstrated after reaching a considerable size (one case). A deposit in the jejunum presented as a small polyp. Two fibroxanthosarcomas developed as a second tumour within the operative field of a previous malignancy; one of these had been irradiated with 4,500 rads. All primary and secondary tumours showed extremely rapid growth. The palliative effect of radiation and chemotherapy was very variable.
