Epstein-Barr virus mucocutaneous ulcer followed by Hodgkin lymphoma in multiple myeloma patient.

Epstein-Barr virus mucocutaneous ulcers (EBV MCU) are B-cell lymphoproliferative disorders associated with immunosuppression. We report EBV MCU in a multiple myeloma patient on lenalidomide maintenance after stem cell transplant that resolved with decreased immunosuppression. Furthermore, the subsequent development of classical Hodgkin lymphoma suggests an underlying predisposition to EBV-driven lymphoproliferative disorders.
