Abstract
A case of a 64-years-old man who was diagnosed as having idiopathic thrombocytopenic purpura 6 years earlier and was followed without therapy is reported. He was seen in our hospital because of complaints of anorexia and black stool. Gastrointestinal endoscopy showed a type 2 tumor at the gastric antrum, and the histopathological diagnosis was moderately well differentiated tubular adenocarcinoma. Thus, gastric cancer, cT2 (MP), cN0, cM0, cStage IB was diagnosed. For preoperative therapy he received steroid and high-dose immunoglobulin. Distal gastrectomy was performed safely without blood transfusion, the blood platelet count increased after surgery, despite tapering and stopping of the steroid in 2 weeks. The blood platelet counts have been more than 10×104/μL for 2.5 years after surgery.
