Most gastric cancers are adenocarcinomas, but other malignancies can arise in the stomach. Patients with leukemia may develop myeloid sarcoma (MS) in the gastrointestinal tract. Our patient was a 68-year-old woman who was initially diagnosed with acute myeloid leukemia and underwent a matched unrelated stem cell transplantation. She was in remission for 10 years before developing a rare case of gastric MS without acute myeloid leukemia. She had partial response to chemotherapy but ultimately died because of infection. Gastric MS has an incidence of less than 1%. Gastrointestinal involvement usually involves the small intestine and rarely the stomach.
大多数胃癌是腺癌，但胃内也可发生其他恶性肿瘤。白血病患者可能在胃肠道发生髓系肉瘤（MS）。我们的患者是一名68岁女性，最初被诊断为急性髓系白血病并接受了匹配的无关供者干细胞移植。她缓解了10年，之后发生了1例罕见的无急性髓系白血病的胃MS。她对化疗有部分反应，但最终因感染死亡。胃MS的发病率低于1%。胃肠道受累通常累及小肠，很少累及胃。
