Abstract
Background
Multiple myeloma (MM) is a malignant disorder of plasma cells and includes 1% of all malignancies and 10% to 13% of hematologic cancers. Multiple myeloma, characterized by malignant proliferation of plasma cells, leads to the production of monoclonal immunoglobulins. Pleural involvement by plasma cells in multiple myeloma is rare.
Case Report
We report a 61-year-old woman with myelomatous pleural effusion in MM.
Conclusion
A few cases of pleural effusion secondary to MM, in literature, with an incidence of less than 1%, were reported.
