Laryngeal stenosis as a late complication of plasma cell mucositis of the larynx.

Plasma cell mucositis (PCM) is a rare inflammatory condition of the upper aerodigestive tract with a heterogeneous clinical course. Predominately seen in the oral cavity, laryngeal involvement and the requirement for tracheostomy have been rarely described. We describe the case of a man diagnosed with airway-threatening PCM isolated to the larynx requiring a tracheostomy. He responded to oral glucocorticoids and was decannulated only to present 3 years later with severe laryngeal stenosis requiring repeat tracheostomy insertion. Medical management in the form of immunosuppression is the mainstay of treatment for plasma cell mucositis. Surgical management is necessary in a significant proportion of cases with laryngeal involvement.
