The hydroa vacciniforme-like lymphoma is uncommon clinically ,and it is easy to misdiagnosed .The effect of tra-ditional therapy is poor ,while the allogeneic hematopoietic stem cell transplantation followed by lymphocyte and donor-derived EBV-specific cytotoxic T -lymphocyte immunotherapy is effective ,which may offer an curable therapy for HVLL.
