title: [Subglottic metastasis of multiple myeloma. Case report and review of the literature of laryngeal plasmacytoma].
abstract: A total of 111 cases of laryngeal plasmacytoma have now been reported. The disease may present either as a primary extramedullary plasmacytoma (n = 90) or as a metastasis of a multiple myeloma (n = 21). The distinction between these two types is very important in therapy and prognosis. We report a subglottic plasmacytoma in a 48-year-old woman. Investigations showed bone marrow infiltration, osteolysis and light chain expression in serum, indicating generalized disease. Therefore polychemotherapy was given, during which complete macroscopic and microscopic regression of the laryngeal plasmacytoma was observed. However, 14 months later, the patient died of renal failure due to systemic progression of the multiple myeloma.
