Abstract

Hepatocellular carcinoma (HCC) is uncommonly observed as a cutaneous metastasis. We report a 76-year-old man with metastatic HCC to the skin of the nasal ala, diagnosed antecedent to the primary tumor. HCC was confirmed by positive immunostaining with Hep Par 1 in tissue from the metastasis and from a needle biopsy of the primary lesion. In addition, tumor cells from both the metastasis and liver stained positive with HMB-45. To our knowledge, HMB-45 positive staining has not been reported in either primary or metastatic HCC.
