Skin manifestations range from a mild, asymptomatic exanthem-like eruption to full-thickness skin loss resembling toxic epidermal necrolysis. Hepatic involvement is characterized by elevated total bilirubin. Gastrointestinal disease manifests as abdominal pain, nausea/vomiting, and secretory diarrhea.The most important risk factor for chronic GVHD is a history of acute GVHD. Traditionally, acute features present prior to day 100 posttransplantation, and chronic manifestations after 100 days; however, overlap between “classic” acute and chronic features may occur.Chronic GVHD of the skin is remarkably variable in clinical presentation. Epidermal involvement may resemble lichen planus, keratosis pilaris, or psoriasis. Sclerotic changes may resemble lichen sclerosus, morphea, systemic sclerosis, or eosinophilic fasciitis.The pathogenesis of chronic GVHD is poorly understood and nearly every organ system is at risk. The skin, oral mucosa eyes, gastrointestinal tract, and lungs are most frequently involved. In many cases, organ system disease resembles known autoimmune conditions.Optimal dermatologic management of chronic GVHD of the skin requires an understanding of other organ involvement, infection status, and cancer relapse risk. Close communication with the transplant physician and a “team approach” to multispecialty management is needed.
