We are reporting a case of a 75-year-old man with multiply recurrent IgA-lambda multiple myeloma status post multiple rounds of chemotherapy, autologous stem cell transplantation, and palliative radiation therapy for diffuse bone lesions. Approximately 15 years after original diagnosis, he developed secondary cutaneous plasmacytomas of the right arm, right chest wall, and right upper back over the course of several months. He underwent palliative involved field 3D conformal photon or en face electron therapy concurrently with various chemotherapy regimens and achieved good to complete response with palliation of pain at the irradiated sites. He died of complications related to his disease approximately 7 months after developing skin lesions. The case presented is unique for dermal involvement of myeloma treated with palliative involved field radiation. 1
