T-cell lymphoproliferative disorder following mycophenolate treatment for myasthenia gravis.

Immunosuppressive therapies are critical in the management of numerous conditions including myasthenia gravis. Mycophenolate mofetil is a widely used, oral immunosuppressive agent that is considered to have few adverse effects compared with similar drugs. We report the case of a patient who developed T-cell lymphoproliferative lesions following long-term treatment with mycophenolate mofetil and prednisone for myasthenia gravis. The lesions resolved following cessation of the treatment. This case highlights a serious complication of a commonly used drug.
