Chronic graft-versus-host disease (cGVHD) is a frequent complication of allogenic bone marrow transplantation. Even with aggressive treatment, cGVHD is associated with a significant degree of morbidity and mortality. cGVHD resembles autoimmune disorder, particularly systemic sclerosis (SSc). Sarpogrelate hydrochloride (SH) is an antagonist of the 5-hydroxytryptamine2A (5HT2A) receptor and has been reported to be effective in the treatment of systemic sclerosis (SSc) patients with Raynaud phenomenon. We used SH to treat a cGVHD patient, and we measured plasma PDGF and total TGF-beta levels. After SH treatment, his plasma PDGF and total TGF-beta levels decreased, and he noticed improvement in his skin pigmentation. In the present case, SH may have improved the skin lesion by inhibiting the synthesis of PDGF and TGF-beta.
