Extramedullary plasmacytoma of the larynx

Extramedullary plasmacytomas, indistinguishable histologically from multiple myeloma, are fairly uncommon tumors, which are most frequently located in the upper airways. However, the larynx is rarely involved. Ten per cent of reported cases have multiple lesions. The patient reported here had a plasmacytoma of the right false vocal cord which was removed by laryngofissure one month after irradiation treatment (50 Gy) since the tumor showed only a slight regression. Tonsillectomy was performed for another plasmacytoma of the left tonsil. The patient has now been followed for seven years, and there has been no evidence of systemic disease.
