{Reference Type}: Case Reports {Title}: Psoriasiform graft-versus-host disease responded to secukinumab: A case report. {Author}: Gu Y;Sun J;Zhang J; {Journal}: Australas J Dermatol {Volume}: 64 {Issue}: 4 {Year}: 2023 Nov 31 {Factor}: 2.481 {DOI}: 10.1111/ajd.14144 {Abstract}: We describe a 9-year-old boy who developed generalised erythematous lesions 12 months after haematopoietic stem cell transplant (HSCT). Histopathology showed both features of psoriasis and graft-versus-host disease (GVHD). The lesions responded well to secukinumab, suggesting that IL-17A monoclonal antibody might be a treatment option for GVHD.
