Sclerodermatous Graft-Versus-Host Disease: A Rare Sequela of Hematopoietic Stem Cell Transplantation.

Although graft-versus-host disease (GVHD) is a common immunologic reaction after an allogeneic hematopoietic stem cell transplant (HSCT), progression into sclerodermatous GVHD is a rare sequela. It can present locally or generalized with various cutaneous and mucocutaneous manifestations, resulting in loss of skin elasticity and reduced functional capabilities. One of the most debilitating consequences of sclerodermatous GVHD is its effect on a range of motion due to fibrosis of the skin and subcutaneous fat. We present the case of a 54-year-old male with a medical history of acute myeloid leukemia and an allogeneic stem cell transplant who was diagnosed with sclerodermatous GVHD. We review the characteristic clinical and histopathological findings of sclerodermatous GVHD, as well as its treatment. Early recognition and intervention are crucial to prevent complications, such as joint contractures.
