Description

A case of a resected hepatocellular carcinoma (HCC) with sarcomatous change that recurred in an early period as a huge tumor of the abdominal wall is reproted. A 65-year-old man was admitted in our hospital complaining of upper abdominal pain. He was found to have a tumor, 4.0 cm in diameter at the lateral upper segment of the liver by imaging diagnosis. He was diagnosed as having HCC, poorly differentiated type, and underwent partial hepatectomy. Histologically, the tumor consisted mostly of spindle cells or giant cells, growing medullary, and was diagnosed as HCC with sarcomatous change. There was local recurrence in the abdominal wall with hemorrhage around the resected liver 1 month after hepatectomy. This tumor grew rapidly and became about 20 cm in diameter 2 months after hepatectomy. The doubling time of this tumor was 11.9 days. We suggest that it is necessary to perform hepatectomy as much as possible in HCC with sarcomatous change, which has high malignancy.
