The chronic graft-versus-host disease often requires unceasing immunosuppressive therapy (IST), which increases a risk of infectious complications in hematopoietic stem cell transplantation (HSCT) recipients. We report an adult T-cell leukemia/lymphoma case who developed pulmonary nocardiosis, a rare pulmonary complication, after allogeneic HSCT despite administration of the prophylactic trimethoprim-sulfamethoxazole (TMP/STX). The inhaled corticosteroid in addition to systemic IST had been started for bronchiolitis obliterance 4 months prior to nocardiosis development. The patient was successfully treated with an increased dose of TMP/STX combined with meropenem. Transplantation physicians should keep this rare pulmonary complication in mind during sustained IST.
慢性移植物抗宿主病通常需要持续的免疫抑制治疗（IST），这增加了造血干细胞移植（HSCT）受者发生感染并发症的风险。我们报告了1例成人T细胞白血病/淋巴瘤病例，该患者在接受异基因HSCT后，尽管使用了预防性甲氧苄啶-磺胺甲恶唑（TMP/STX），仍发生了罕见的肺部并发症——肺诺卡菌病。在发生诺卡菌病前4个月，已开始使用吸入性糖皮质激素联合全身IST治疗闭塞性细支气管炎。该患者通过增加TMP/STX剂量联合美罗培南成功治愈。移植医生在持续进行IST治疗期间应牢记这种罕见的肺部并发症。
