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.
