Clinical aspects of sclerodermatous type graft-versushost disease after allogeneic hematopoietic cell transplantation.

Objective: We aimed to evaluate the clinical features of sclerodermatous chronic graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (AHSCT). Materials and Methods: We retrospectively analyzed 423 patients who underwent AHSCT. We assessed age, sex, pretransplant diagnosis, conditioning regimen, GVHD prophylaxis, and occurrence of acute GVHD (aGVHD), chronic lichenoid and chronic systemic GVHD, and clinical properties of sclerodermatous GVHD. Results: Sclerotic skin lesions developed in 22 patients after a mean of 752±647 days (median 480). aGVHD appeared in 17 patients, with hepatic involvement in 2, gastrointestinal tract involvement in 2 and skin involvement in 13 of these patients. Extensive chronic GVHD (liver, pulmonary, skin and oral mucosa) developed in 12 patients. Sclerosis was generalized in 19 patients (86.4%) and localized in 3 patients (13.6%). Leopard skin eruption appeared in 8 (36.4%) of the 19 patients with generalized sclerodermatous changes. In most cases, sclerotic lesions appeared on the trunk, and distal parts of the extremities were spared. Eight patients (36.4%) progressed from lichenoid to sclerodermatous lesions, 2 (9.1%) with lichenoid and sclerodermatous phases together and 12 (55.5%) with de novo sclerodermatous lesions. Five patients died because of late transplant-related complications. Conclusion: Sclerodermatous GVHD has a late onset and may be quite disabling. Unlike scleroderma, acral involvement is seen rarely. Although most lesions do not disappear in the course of the disease, most patients have a good prognosis. [ABSTRACT FROM AUTHOR]
