A 67-year-old man presented with an asymptomatic swelling in the lateral surface of the left thigh three years after resection of a carcinoma of the left colon and synchronous liver metastasis (tumor–node–metastasis stage T3N2M1, according to International Union against Cancer staging) and subsequent chemotherapy. A computed tomographic (CT) scan showed an isodense formation beside the quadriceps muscle (Panel A, arrow). A positron-emission tomographic scan showed signal enhancement in the left thigh due to enhanced metabolic activity of this lesion (Panel B, arrow). The patient underwent surgical resection of the lesion, and histologic examination confirmed metastasis of the colon carcinoma. Two months later, a CT scan revealed the growth of intraabdominal lymph nodes, and the patient was treated with chemotherapy. Because of further tumor progression in the lung and bone, treatment with a salvage regimen is presently ongoing.
