Abstract
Liver is the most common site of recurrence of gastric gastrointestinal stromal tumor (GIST). In most cases, the recurrence occurs within 2 years of the resection of the primary lesion. However, in our patient, liver metastasis occurred 11 years after initial surgery.
A 60-year-old man underwent proximal gastrectomy in 1997 for a submucosal tumor of the stomach. Gastric leiomyosarcoma was diagnosed on the basis of immunohistochemical examination performed at that time. In 2008, a liver tumor was detected during an abdominal ultrasound in a voluntary health screening. After close inspection, we suspected metastasis of the GIST to the liver and partial hepatectomy was performed in December, 2008. Immunohistochemical examination revealed that this liver tumor was caused by metastasis of the GIST.
