Severe Erythroderma Due to Adult-onset Still's Disease-like Disease Related to Graft-versus-host Disease after Allogeneic Hematopoietic Stem Cell Transplantation

抄録

A 35-year-old woman was treated with chemotherapy for leukemia. One year later, allogeneic hematopoietic stem cell transplantation (HSCT) was performed with umbilical cord blood. After nine months, she developed a spiking fever, sore throat, arthralgia, pleural effusion, hyperferritinemia, and persistent generalized pruritic erythema. A skin biopsy showed dyskeratotic cells in the epidermis, neutrophil infiltration in the epidermis and upper dermis, and neutrophils in the parakeratotic layer. Treatment with tocilizumab was effective. Adult-onset Still's disease (AOSD)-like disease related to graft versus-host disease (GVHD) after HSCT was suspected. Abnormal immune states related to GVHD may cause AOSD-like disease with more severe skin lesions than usual.
