Abstract
Severe aplastic anemia (SAA) and nasopharyngeal carcinoma (NPC) are two different diseases and are life-threatening if left untreated. The co-occurrence of SAA and NPC is rare and presents a complex therapeutic paradox. This study reports a unique case of a patient diagnosed with both SAA and NPC. The patient initially underwent haploidentical hematopoietic stem cell transplantation (HSCT) to achieve rapid hematologic recovery, followed by nimotuzumab + radiotherapy for carcinoma treatment. This case suggests that sequential haploidentical HSCT and radiotherapy may represent a promising therapeutic strategy for patients with coexisting SAA and NPC.
