A Case of Huge Hepatic Recurrence of Low Risk Gastrointestinal Stromal Tumor / 대한내과학회지

ABSTRACT

Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors that express c-kit. The majority of GISTs are located in the stomach and small intestine. The tumors are classified into very-low-risk, low-risk, intermediate-risk, and high-risk categories based on size and mitosis activity. The recurrence of low-risk GIST is extremely rare. We report a hepatic recurrence of a low-risk gastric GIST that had been removed completely 8 years earlier, and presented as a huge hepatic mass. Since recurrent GIST has a poor prognosis, regular long-term follow-up must be considered, although the primary GIST was low risk.
