title: Successful treatment of oral lichen planus-like chronic graft-versus-host disease with topical tacrolimus: a case report.
abstract: BACKGROUND
  Bone marrow transplantation (BMT) is a common treatment used for deficiencies of host marrow or in the control of blood malignancies. Post-allogeneic BMT complications include graft-versus-host disease (GVHD). GVHD occurs when immunologically active T lymphocytes are transplanted into an immunosuppressed recipient who is genetically disparate from the donor. In this case report we describe the occurrence of oral lichen planus-like lesions as the first manifestation of chronic GVHD (c-GVHD) and the subsequent management of this disease with topical tacrolimus.
  
  
  METHODS
  Diagnostic aids included routine histology and direct immunofluorescence studies to rule out immunobullous diseases and to confirm the c-GVHD. Treatment consisted of topical application of 0.1% tacrolimus ointment three times a day.
  
  
  RESULTS
  Routine histology confirmed the clinical diagnosis of oral lichen planus-like c-GVHD. Treatment with tacrolimus ointment completely resolved the oral lesions after 2 months of therapy.
  
  
  CONCLUSIONS
  Topical tacrolimus at low concentrations (0.1%) shows promise in the management of oral lichen planus-like c-GVHD. Controlled studies are necessary to assess the efficacy, the duration of therapy required for effective results, and the safety of this treatment over the long-term.
