Cutaneous manifestations of chronic graft-versus-host disease.

Graft-versus-host disease (GVHD) occurs in a number of clinical settings. It is well recognized after bone marrow transplantation, an increasingly used therapeutic option for haematological disorders. Chronic GVHD, occurring at an interval greater than 100 days post-transplant, has many systemic manifestations, but it is the cutaneous manifestations which are most frequent and often most troubling to the patients. In this review article, the wide spectrum of cutaneous chronic GVHD (including involvement of hair, nails and mucosae), and its complications and associations are discussed. The clinical and histological features and management guidelines are presented to assist the dermatologist with diagnosis and treatment of this condition.
