Transient iatrogenic immunodeficiency-related B-cell lymphoproliferative disorder of the skin in a patient with mycosis fungoides/Sézary syndrome

Immunodeficiency‐related lymphoproliferative disorders (IR‐LPD) may occur in the setting of immunosuppressive therapy with methotrexate and TNF‐α antagonists. As far as we are aware, this is the first report of an Epstein‐Barr virus‐associated B‐cell lymphoproliferative disorder, secondary to methotrexate therapy in a patient with mycosis fungoides/Sézary syndrome.
