Chronic graft-vs-host disease (GVHD) is a frequent complication in patients who receive allogeneic hematopoietic cell transplants (HCTs), and the skin is the most common site of involvement. Chronic cutaneous GVHD can present with sclerotic or nonsclerotic changes and often requires treatment with systemic immunosuppressants, extracorporeal photopheresis, or phototherapy. Immunosuppressants carry the potential of causing important side effects, so additional modes of therapy with better security profiles are clearly needed. We report a case of an eleven year old girl, who received allogeneic HCTs to treat acute lymphocytic leukemia. She developed sclerotic chronic GVHD. The patient underwent treatment with narrowband UV-B phototherapy, and a significant improvement was seen over the first 2 months. There are a number of successful series and case reports on different forms of phototherapy. In relation to narrowband UV-B phototherapy, literature is scarce, although shows important results in sclerotic and nonsclerotic forms of chronic cutaneous GVHD and a good safety profile have been seen. Anyway, large-scale controlled prospective trials are needed to evaluate the effectiveness of phototherapy as adjuvant o even first-line therapy, and to establish the most effective therapy schemes and doses.
