title: Pulmonary plasmacytoma with endobronchial extension: A rare presentation of solitary extramedullary plasmacytoma: A case report and brief review of literature.
abstract: Extramedullary plasmacytoma is the malignant proliferation of single clone of plasma cells arising outside the bone marrow. Solitary extramedullary plasmacytoma (SEP) are solitary lesion mostly located in upper respiratory tract and nasopharynx. Involvement of lower respiratory tract is rarely seen in case of SEP. Here, we report a rare case of pulmonary plasmacytoma in a 50-year-old male presenting as left lower lobe lung mass with endobronchial extension. Subsequent investigations, histological and immunohistochemical examination of tumor confirmed the diagnosis of plasmacytoma. Work-up for the multiple myeloma came out to be negative, thus confirming the diagnosis of SEP. Pulmonary plasmacytoma, a rare presentation of extramedullary plasmacytoma should be kept in mind by dealing with the patients of lung mass and endobronchial extension.
