title: Solitary tracheal plasmacytoma.
abstract: Primary tracheal tumours are rare and trachea is an exceedingly rare site of extramedullary plasmacytoma. We report a case of extramedullary plasmacytoma involving trachea and causing symptoms of airway obstruction in a 44-year-old man. Chest radiograph was normal. Flow-volume loop showed characteristic pattern localizing the lesion at thoracic inlet. Computerised tomography and bronchoscopy demonstrated a broad based pedunculated intratracheal mass obstructing 85% of the lumen. Tracheal tumour was excised via low tracheostomy. Histopathology of resected mass revealed extramedullary plasmacytoma. Relevant investigations excluded multiple myeloma. He was managed with radiotherapy with good response and there has been no recurrence after one-year follow-up.
