Dermatopathic lymphadenopathy with Langerhans cell chimerism in graft-versus-host disease of the skin

Zusammenfassung

Dermatopathic lymphadenopathy (DL) is well-known in inflammatory skin disease; however, it has not been reported in graft-versus-host disease (GvHD) after allogeneic stem cell transplantation. Here, we report 2 cases of DL in patients with acute GvHD of the skin and demonstrate complete donor chimerism of Langerhans cells within the lymph nodes.
