Disseminated Kaposi's sarcoma in a child treated with allogeneic hematopoietic stem cell transplantation

Kaposi's sarcoma (KS) is a rare complication of hematopoietic stem cell transplantation (HSCT). Here, we report a case of disseminated KS in a pediatric patient after haploidentical HSCT that developed during secondary immunosuppression. Treatment with liposomal doxorubicin resulted in a complete metabolic response. This case highlights the importance of early diagnosis and stresses the need to consider KS in the differential diagnosis of cutaneous and systemic manifestations in patients following HSCT. The patient's parents gave consent to the use of their child's data, including photographs, for research purposes and in publications.
