Allogeneic hematopoietic stem cell transplantation for juvenile myelomonocytic leukemia with intestinal Behçet's disease: A case report

Abstract Behçet's disease (BD) is a rare condition that is seldom associated with hematological malignancies. In this case report, we present the unique case of a 7‐year‐old girl diagnosed with juvenile myelomonocytic leukemia (JMML) and intestinal BD. The patient received allogeneic hematopoietic stem cell transplantation (allo‐HSCT), which resulted in complete remission of both JMML and BD. Our findings suggest that allo‐HSCT may be a feasible treatment option for JMML patients with coexisting BD, and holds promise for achieving remission of both illnesses. However, further clinical investigations are needed to validate these findings.
