ABSTRACT
The patient was a 77-year-old woman. She underwent a partial gastrectomy at the age of 40, and a partial colectomy at the age of 75 following a diagnosis of a carcinoid. In November 2019, a 1.5 cm mass with a clear boundary was found in the pancreatic tail, which was strongly stained uniformly. And furthermore, multiple masses between 2 cm and 3 cm with a clear boundary was found inside liver segment S1 and S6 and S7 and S8 on CT, which was strongly stained at the edge in the early phase and was seen as a low density area in the late phase. At a result of image examination, it was diagnosed as a pancreatic tail neuroendocrine tumor and its multiple liver metastases. The distal pancreatectomy, posterior segmentectomy, and partial S1 lt and S8 liver resection were performed. With postoperative pathological diagnosis, the pancreatic tumor was accessory spleen, and liver tumor were epithelioid type GIST which were positive for CD34 and PDGFRA and negative for c- kit. The pathology specimen of colectomy was re-examined, and the diagnosis from the previous surgery was changed to GIST from a carcinoid. Epithelioid type GIST was associated with a PDGFRA gene mutation and was known to have many gastric origins. Based on the clinical course, it was diagnosed as recurrence of gastric GIST at 40 years after 30 years or more.
