Solitary Extramedullary Plasmacytoma of the Larynx Presenting with Stridor as a Primary Manifestation

Abstract

More than 90% of malignant tumors of the larynx are squamous cell carcinomas. Extramedullary plasmacytoma is a plasma cell tumour representing less than 1 % of all head and neck malignancies and involvement of the larynx is very rare. In the larynx the supraglottis is the primary site of involvement compared to the glottic and subglottic regions. We report a case of 54-yearold Indonesian female who presented at our clinic with stridor as primary manifestation secondary to solitary extramedullar plasmacytoma involving the glottis and subglottis of the larynx. The patient underwent microlaryngoscopy, biopsy and CO2 laser excision of the tumour with significant improvement of the airway and was referred for locoregional radiotherapy. We review the literature and discuss the management of this rare condition.
