Thyroid cartilage involvement in patient affected by IgA multiple myeloma: case report.

Neoplasms originating from plasma cell are rare in the head and neck region. A correct clinical evaluation is very important in order to formulate a differential diagnosis as well as to distinguish local from metastatic disease. We report a case of larynx involvement by an IgA multiple myeloma in a 69-year-old female diagnosed in October 2004 and treated with chemotherapy; the 1 year control do not show progression of disease and the laryngeal lesion is unchanged. We highlight the radiological findings and clinical features to suspect plasma cell tumors in cases with a similar presentation.
