Use of Lenalidomide in 5q-Myelodysplastic Syndrome Provides Novel Treatment Prospects in Management of Pulmonary Sarcoidosis.

We present the case of a 71-year-old woman with a long-standing history of refractory pulmonary sarcoidosis, who, upon commencement of treatment with lenalidomide for her newly diagnosed 5q-myelodysplastic syndrome, showed a remarkable, immediate, unexpected response and recovery of her sarcoidosis-related symptoms, improvement of her vital capacity, and complete clearance of her bibasal alveolor infiltrates. To our knowledge, this is the first case to report on the significant and immediate efficacy of lenalidomide in the management of pulmonary sarcoidosis. It provides a potential role for the use of lenalidomide as a novel therapeutic agent in patients with refractory pulmonary sarcoidosis.
