A 58-year-old Japanese man underwent partial gastrectomy in 1991 for a tumor showing extra-gastric growth measuring 18 x 16.5 x 8.8 cm in size. An immunohistochemical study yielded a diagnosis of gastric GIST with few mitoses. In 2004, abdominal CT showed a solitary liver metastasis without extrahepatic recurrence and right hepatic lobectomy was performed. No adjuvant treatment has been done and he is alive without recurrence 1 year after the hepatectomy. Long term follow-up of more than 10 years is required after resection of primary tumors if they are diagnosed as high risk GISTs with few mitoses.
