Herein is presented a case of aplastic anemia associated with adenocarcinoma of the stomach which seem- ed to be coincidental. A 52 year-old man was admitted with a 3 year history of dyspnea. Three years previously, he was diagnosed as bone marrow hypoplasia and had been treated with oxymetholone for 1 year. After confirmation of aplastic anemia during the first admission, he was followed up with fluoxymesterone and steriods. One year later, he was readmitted with melena. Fibergastroscopy and an UGl study revealed a fungating mass on the antrum suggestive of stomach cancer. Following perioperative platelet transfusions and intensive supportive care, a subtotal gastrectomy was performed and there were no postoperative complications. Pathologic examinations disclosed a moderately well differentiated adenocarcinoma. This is the first report in Korea of adenocarcinoma of the stomach occurring in a patient with aplastic anemia. He survived 17.5 months after the surgery and 5.4 years after the onset of aplastic anemia. Gastrointestinal bleeding in aplastic anemia may be incorrectly ascribed to steriod use and overlooked, thus the need to fully investigate gastric pathology by endoscopy as well as radiology is streesed. In a patient with pancytopenia, the major surgical procedures are frequently evaded by both surgeons and internists due to the possibility of morbidity from bleeding and infection. In this case, intensive perioperative supportive care and surgery were combined to prolong the patient's survival time.

Anti-erythropoietin antibodies usually cross-react with all kinds of recombinant erythropoietins; therefore, erythropoiesis-stimulating agent (ESA)-induced pure red-cell aplasia (PRCA) is not rescued by different ESAs. Here, we present a case of ESA-induced PRCA in a 36-yr-old woman with chronic kidney disease, whose anemic condition improved following reintroduction of darbepoetin-alpha. The patient developed progressive, severe anemia after the use of erythropoietin-alpha. As the anemia did not improve after the administration of either other erythropoietin-alpha products or erythropoietin-beta, all ESAs were discontinued. Oxymetholone therapy failed to improve the transfusion-dependent anemia and a rechallenge with ESAs continuously failed to obtain a sustained response. However, her anemia improved following reintroduction of darbepoetin-alpha at 3 yr after the initial diagnosis. Interestingly, anti-erythropoietin antibodies were still detectable, although their concentration was too low for titration. In conclusion, darbepoetin-alpha can improve ESA-induced PRCA when the anti-erythropoietin antibody titer declines and its neutralizing capacity is lost.
