Abstract: | BACKGROUND: Graft vs. host disease (GVHD) is a common complication of bone marrow transplantation (BMT) but is rarely seen after solid organ transplantation. METHODS: We report a case of lichenoid GVDH arising in a 60-year-old man 10 weeks after orthotopic liver transplantation. RESULTS: Skin biopsies revealed changes suggestive of lichenoid GVHD, but histological features differed from those described in post bone marrow (stem cell) transplant GVHD, in that a dense lymphoid infiltrate was present. The brisk infiltrate contained eosinophils that initially led to concern for a lichenoid drug eruption. The patient developed multiorgan GVHD after reduction in immunosuppression. The diagnosis of chronic GVHD was confirmed by the demonstration of chimerism in the patient's peripheral blood. The generalized cutaneous eruption and systemic manifestations responded to salvage therapy including intravenous immunoglobulin infusion, increased immunosuppression with high-dose steroids, mycophenolate mofetil, and systemic and topical tacrolimus. CONCLUSIONS: In interpreting skin biopsies, it is important to recognize that brisk inflammation may be seen in GVHD in the setting of solid organ transplantation, in contrast to the more sparse inflammation typical of GVHD following BMT. The clinical and histologic differential diagnosis included the eruption of lymphocyte recovery, drug reaction, and viral exanthem. We provide a conceptual framework for evaluating generalized cutaneous changes that may occur post transplantation. |
