Radiotherapy for multiple myeloma with skin involvement.

Multiple myeloma metastatic to the skin is a rare occurrence that usually reflects a high tumour burden. Here, we report the case of a woman with known multiple myeloma who developed cutaneous lesions on the right leg. Limited-field radiation treatment was successfully used to decrease her tumour bulk. Unfortunately, the patient died of complications related to systemic treatment a few months after developing the cutaneous involvement.
