Cricoid-based extramedullary plasmocytoma

J Craniofac Surg. 2011 Nov;22(6):2361-3. doi: 10.1097/SCS.0b013e318231e56d.


Extramedullary plasmocytomas are solitary, vascular, soft tissue plasma cell tumors without evidence of multiple myeloma (MM) that represent approximately 1% of head and neck malignancies. Approximately one third of them disseminate to MM within 2 years from presentation. Extramedullary plasmocytomas have been reported to involve larynx in 6% to 18% of cases, most commonly affecting the epiglottis and the ventricle, followed in order by the true vocal cord, false vocal cord, aryepiglottic fold, arytenoids, and subglottis. In this report, we describe a case of plasmocytoma involving the cricoid, the left cricoaritenoid joint, and the homolateral vocal process that developed MM 1 year after primary treatment.
