Of head and neck malignancies extramedullary plasmacytoma occurs in less than 1% cases. It is the rarest primary laryngeal malignancy. A 65-year-old man presented with dry cough and breathlessness for last 6 months. Direct laryngoscopic examination showed a gray-white submucosal mass in the subglottic region. Histopathological examination showed presence of pseudostratified columnar epithelium with underlying stroma having mature and immature plasma cells. The cells were mono to bi-nucleated having eccentric nuclei and condensed spoke like chromatin. Few cells had centrally placed nuclei with small but conspicuous nucleoli. Some cells resembling Reed-Sternberg cells were also seen. The patient was successfully treated with primary radical radiotherapy and showed no signs of local recurrence after a 12-month follow-up.
