Sclerodermatous chronic graft-versus-host disease after allogeneic hematopoietic stem cell transplantation: incidence, predictors and outcome.

Scleroderma may be one of the most severe forms of chronic graft-versus-host disease (GVHD). We retrospectively evaluated its incidence, predictor variables and outcome in 133 patients who survived at least 4 months after allogeneic hematopoietic stem cell transplantation. The 5-year cumulative incidence was 15.5% in patients with chronic GVHD. The generalized form had a progressive course despite immunosuppressive therapy. Eosinophilia, autoimmune markers, and previous skin involvement by chronic GVHD with disorders of pigmentation were significantly associated with an increased probability of developing scleroderma.
