Title: Multiple Myeloma with Different Thoracic Manifestations: Case Series
Abstract: Multiple myeloma is a malignant proliferation of the plasma cells mainly affecting bone marrow, but other organs may also be involved.Multiple myeloma is rarely associated with lung plasmacytoma.Patients with extramedullary plasmacytomas have coexistent multiple myeloma in only 5% of cases.The incidence of malignant pleural effusion in multiple myeloma is very low and is approximately 1%.In this case series, we report three patients with multiple myeloma, who presented with different thoracic manifestations such as left-sided myelomatous pleural effusion, posterior mediastinal mass with central airway obstruction, and pulmonary consolidation.
