Owing to the development of high-frequency probes, reports of sonography in the field of soft tissue have been increased. However, sonographic features of skin tumors have been rarely mentioned until now. Metastatic carcinoma of the skin is uncommon, and its clinical appearance of cutaneous metastasis is neither distinctive nor diagnostic in many cases. Here we describe the sonographic features of five cases of metastatic skin tumors, all of which had been confirmed by histology. Sonogram revealed characteristic patterns, such as round, hypoechoic, well margined, internal echo, and posterior enhancement. Furthermore, sonogram well demonstrated the relation with surrounding tissue. Resected tumors were pathologically examined, and the depth and size were found to be closely similar to the sonographic findings. When skin nodules are present in the cancer patient, sonographic study may be useful for differential diagnosis and preresectional study.
