Persistent Plasma Cell Tumor of the Nasopharynx after Radiotherapy Treatment: A Case Report and Review of the Literature

Extramedullary plasmacytoma of the head and neck region is a rare malignant tumor comprising approximately 3% of all plasma tumors. Approximately 80-90% involve the mucosa of the upper airway. These tumors are known to be very radiosensitive and therefore radiotherapy is considered the treatment of choice, surgery being limited to biopsy and to excision residual disease. A case of extramedullary plasmacytoma of the nasal cavity is reported wich did not respond to radiotherapy.
