Hepatocellular carcinoma (HCC) is the most common primary malignant tumor of the liver. There are some reports of primary extrahepatic HCC. But there is no report of HCC presenting as primary thigh mass. We report a case of HCC as a palpable mass in the right thigh, without hepatic lesion. On an MRI, the mass showed non-specific signal intensity and was progressively and centripetally enhanced.
