Sudden clinical course of an unusual ENT tumour: clinical pictures of extramedullary plasmacytoma secondary to multiple myeloma.

Extramedullary plasmacytoma (EMP) is a rare monoclonal plasmacytic proliferation involving upper airways in 80\% of cases. The heterogeneous pattern of frequency in the head and neck area may result in insidious clinical expressions that are potentially lethal for the patient. The presentation and management of two suggestive clinical photographs characterized by sudden and aggressive EMP development secondary to multiple myeloma are discussed.Abstract available from the publisher.
