Tracheobronchopathia osteochondroplastica is characterized by ossified mucosal nodules which protrude into the lumen of the larynx, trachea and bronchi. We report here a 41-year-old man who had psoriatic arthritis for 16 years. He had worked in brake-lining factory for car rim production and brake construction so there he was exposed to occupational asbestos. By fiberoptic bronchoscopy (FOB) there were diffuse mucosal roughening, irregularity and nodularity in the trachea. A biopsy of the subglottic lesions was taken by direct laryngoscopy and diagnosis was made. Although coexistence of this entity with other autoimmune diseases is defined, coexistence with psoriasis has not been previously reported.
