The differential<unk>  of GvHD is broad given the complexity of post-transplant patients. Infectious etiologies must be considered in persons who under stem cell transplant. A skin rash in the post-transplant setting, for example, could reflect infectious dermatitis or skin GvHD. Liver dysfunction in the post-transplant setting, for example, can reflect an infectious hepatitis of liver GvHD. Gastrointestinal symptoms in the post-transplant setting, for example, could reflect infectious enteritis/colitis or GI GvHD. Chronic graft-versus-host<unk>  must be differentiated from other<unk> s that cause skin thickening such as scleredema, scleromyxedema, eosinophilic fasciitis, scleroderma, drug induced scleroderma, scleroderma overlap syndromes, diabetic cheiroarthropathy, myxedema, and nephrogenic systemic fibrosis.
