Summary
A rare case of primary hepatocellular carcinoma in the diaphragm was diagnosed and surgically removed. This diaphragmatic tumor, initially suspected as a gastric submucosal tumor, showed complete remission 8 years post-operation.
Area of Science:
- Hepatobiliary Surgery
- Surgical Oncology
- Gastroenterology
Background:
- Primary liver cancer, hepatocellular carcinoma (HCC), typically originates in the liver parenchyma.
- Extraparenchymal HCC, especially in unusual locations like the diaphragm, is exceptionally rare.
- Elevated alpha-fetoprotein (AFP) can indicate HCC, but its presence requires thorough investigation for tumor origin.
