[X-ray pattern of metastatic tumors of subcutaneous fat]

The results of X-ray examination of 33 cases of metastases of different malignant tumors into subcutaneous fat are analysed. Such metastases appear in radiographs as single or multiple nodes of a density comparable with that of muscular tissue. They have a homogenous structure and a regular round shape with contours which may be indistinct in some areas. There are dilated vessels at tumor poles. Differential diagnosis between sarcoma, benign tumor and non-tumor process is discussed.
