Acute follicular graft-versus-host disease

We documented by clinical, histopathologic and immunohistochemical analysis a case of acute follicular graft-versus-host disease (GVHD), in which an erythematous-to-violaceous follicular papular eruption constituted the major clinical pattern of cutaneous involvement. Although acute follicular GVHD is rare, it is important to recognize it as an early skin manifestation of acute cutaneous GVHD allowing prompt therapy.
