Abstract
GISTs are mesenchymal tumors that tend to metastasize to the liver, but it is extremely rare for primary liver cancer to initially appear on the liver and then develop subcapsular metastasis after GIST surgery. We reported an 83-year-old man who presented to the hospital with a recurrence of the stromal tumor. A computed tomography scan revealed multiple tumor metastases in the liver capsule and abdominal cavity, and pathology after debulking surgery suggested GIST metastases. The patient’s medical history includes surgical resection for a small intestinal stromal tumor 9 years ago, followed by partial left liver resection 6 years ago due to a newly diagnosed liver lesion initially believed to be GIST liver metastasis, which was later confirmed as hepatocellular carcinoma. The patient is currently on regular repetinib treatment and has been free of recurrence or metastasis for 9 months.
