Аннотация
BACKGROUND: Skin metastases from hepatocellular carcinoma (HCC) represented only 0.8% of all known cutaneous metastases in a recent large series. The most frequent site appears to be the head, but this fact has received little attention. An accurate cytologic diagnosis is extremely difficult in patients with unknown liver dysfunction. We report the cytologic features of a face metastasis from occult HCC.
CASE: A 65-year-old woman presented with a mass in the right preauricular region of 2 months' duration. Her past medical history was noncontributory. Fine needle aspiration cytology was performed. Following the cytologic diagnosis, computed tomography revealed a 6-cm mass in the right lobe of the liver, portal vein thrombosis and involvement of the superior vena cava. The smears were very cellular. The most frequent pattern was trabecular with transmural endothelization. The cells had an epithelial appearance and polyhedral shape, exhibiting distinct borders. The nuclei were centrally placed, with a prominent nucleolus. The cytoplasm was granular. There were numerous atypical bare nuclei. Subsequent staining with antihepatocyte showed positivity in most tumor cells. The final diagnosis was metastatic HCC.
CONCLUSION: HCCs should be considered in the differential diagnosis of carcinomas metastatic to the face, even in the absence of liver symptoms.
