[Solitary extramedullary plasmacytoma of the larynx. Apropos of a case].

The present paper shows a case of solitary extramedullary plasmocytoma of the larynx. It is important to know the limits of this process in order to rule out a multiple myeloma. After a literature review, emphasis is made in the necessity of a very long term patient's follow up, since recurrences may occur some years after the initial diagnostic.
