Pressure-induced isomorphic sclerodermoid graft-versus-host disease from brassiere underwire and tight-fitting watch
Abstract
Sclerodermoid chronic graft-versus-host disease (scGVHD) is a rare form of cGVHD with an estimated prevalence of 3% to 11% in patients receiving allogeneic bone marrow transplants. scGVHD is believed to be an immune-mediated response characterized by aberrant T-cell function and dysregulation of tyrosine kinase cascades. Published literature on scGVHD is still limited and the mechanisms are yet to be fully understood. Thus, successful treatment of scGVHD remains largely unknown and many current options are hindered by potential side effects. This case provides an example of scGVHD localizing to areas of trauma and friction as a potential mechanism behind scGVHD and provides several case reports that document similar findings.
