Chemotherapy was administered following the JALSG APL204 protocol. Induction therapy with all-trans retinoic acid resulted in complete remission on day 49. She developed coccygeal pain from day 18, which spread to the spine and cheekbones and lasted 5 weeks. She had similar bone pain on days 7\u201310 of the first consolidation therapy and on days 4\u201312 of the second consolidation therapy. Oral loxoprofen was prescribed for pain relief. On day 33 of the third consolidation, white blood cell and neutrophil counts were 320\/<jats:italic>\u03bc<\/jats:italic>L and 20\/<jats:italic>\u03bc<\/jats:italic>L, respectively. After she developed epigastralgia and hematemesis, she developed septic shock. Gastroendoscopy revealed markedly thickened folds and diffusely damaged mucosa with blood oozing. Computed tomography revealed thickened walls of the antrum and the pylorus. Despite emergency treatments, she died. Bacterial culture of the gastric fluid yielded <jats:italic>Enterobacter cloacae<\/jats:italic> and enterococci growth. Collectively, she was diagnosed with phlegmonous gastritis. Retrospective examination of serial bone marrow biopsy specimens demonstrated progressive bone marrow fibrosis, which may have caused prolonged myelosuppression. Thus, evaluation of bone marrow fibrosis by bone marrow biopsy after each treatment cycle might serve as a predictor of persistent myelosuppression induced by chemotherapy.<\/jats:p>","DOI":"10.1155\/2019\/1616237","type":"journal-article","created":{"date-parts":[[2019,11,27]],"date-time":"2019-11-27T18:42:29Z","timestamp":1574880149000},"page":"1-7","source":"Crossref","is-referenced-by-count":3,"title":["Prolonged
