Follicular graft-vs-host disease (GVHD) was probably first reported in 1984.1 Clinically acute follicular GVHD was described as an eruption similar to a bacterial or fungal folliculitis following allogenic bone marrow transplantation (BMT).2 Cases of clinically acute and chronic follicular GVHD have been described.3-6 We report the unexpected finding of follicular lichenoid GVHD in a biopsy specimen from a nonspecific lesion that appeared on a patient on the 18th day after BMT.
