Multiple Myeloma Presenting with Multiple Thoracic Manifestations

摘要

Multiple myeloma is a malignant proliferation of plasma cells that affects mainly bone marrow but may also involve otherorgans as well. We report thoracic involvement in the form of left-sided pleural effusion, osseous lesions, bronchialinfiltration, and mediastinal lymphadenopathy in a 61-year-old woman, non-smoker presented with chest pain, dyspnoea,cough and deterioration in general health over the preceding seven months. Immunoelectrophoresis and immunofixationshowed raised kappa-light chain immunoglobulin G (IgG) in serum and pleural fluid. Bronchial and pleural biopsiesdocumented myelomatous infiltration and bone marrow aspirate revealed extensive plasma cell infiltration. At eightmonths, following the fourth cycle of melphalan, endoxan and prednisone based chemotherapy, the patient died.
