Tracheal Lymphoma Presenting with Acute and Progressive Dyspnea

The most common causes of acute airway obstructions are infections, foreign bodies, laryngeal tumors, and allergic reactions. primary tracheal tumors are among very rare causes of acute airway obstructions. tracheal involvement of lymphoma is also not common. in this case report, a 58 year-old woman who presented with acute and progressive airway obstruction was reported. a tracheal mass was detected on computed tomography scan, an emergency tracheostomy was performed, an incisional biopsy was taken, and the histopathological examination revealed a mantle cell variant of primary non- hodgkin lymphoma of the trachea. noother involved site or lymph node could be detected. this is the second primary tracheal mantle cell lymphoma case in the literature.
