We presented one patient who had primary hepatic squamous cell carcinoma. A 73-year-old man we have followed up for hypertension and diabetes mellitus, complained of epigastralgia. Gastrointestinal fiberscopy was performed, and a submucosal tumor was found. Biopsy revealed group 1. CT showed a tumor about 7 cm in diameter between the lateral segment of the liver and the lesser curvature side of the stomach, and absence of the inferior vena cava. Angiograpy showed a hypervascular mass whose blood flow was supplied by the left gastric artery, the short gastric artery and the postgastric artery. We diagnosed as a gastric submucosal tumor and invasion to the liver. So we performed totalgastrectomy and partial lobectomy of the liver. The pathological finding was liver squamous cell carcinoma with invasion to the stomach. After the operation we suspected a metastatic cancer of the liver and examined his entire body, but we did not find another abnormal region. We did not find squamous metaplasia of the intrahepatic bile duct which was responsible for the development of the hepatic squamous cell carcinoma, but we diagnosed a primary hepatic squamous cell carcinoma because we did not find other primary region.

Key words
