Endobronchial extramedullary plasmacytoma. Report of one case

A patient underwent a subtotal resection of the tracheobronchial carina for an obstructing endobronchial lesion. Preoperative biopsies of the lesion were not diagnostic. After resection, the histological examination of the specimen removed demonstrated an extramedullary plasmacytoma infiltrating the bronchial wall. Immunohistochemical studies showed monoclonality for kappa light chains. The postoperative course was uneventful and the screening for multiple myeloma was negative. No adjuvant treatment was given and the patient is currently alive and free of disease 63 months after the resection. Primary endobronchial plasmacytoma is a very rare disease; it is unclear which is the best treatment for endobronchial plasmacytoma. However, complete surgical resection has allowed a long-term survival, free of disease. Copyright (C) 1996 Elsevier Science Ireland Ltd.
