    Abstract:
    Treatment of recurrent acute lymphoblastic leukaemia (ALL) often involves allogeneic stem-cell transplantation (alloSCT) and disease recurrence in the central nervous system may require craniospinal irradiation. Although graft-versus-host disease (GVHD) is a known risk after alloSCT, cutaneous manifestation within radiation fields is rarely seen. The authors report a case of a 25-year-old man with Philadelphia+ALL recurring in the central nervous system after a homologous SCT. Craniospinal radiation was delivered with proton therapy to a total dose of 24 cobalt-Gray-equivalents in 12 fractions. Eight weeks after the proton therapy, significant cutaneous GVHD had developed within the radiation fields. This was treated successfully with tacrolimus (4 mg/day), a short course of methylprednisolone, and topical treatment with 0.1% triamcinolone cream, 0.05% clobetasol ointment. Cutaneous GVHD after SCT can be seen within proton radiation fields probably due to an inherent higher skin dose.
