Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease): a rare case of subglottic narrowing

Abstract
A case of subglottic narrowing caused by an extranodal deposit of sinus histiocytosis in an eight-year-old child with Rosai-Dorfman disease is presented. The airway obstruction was initially managed with a tracheostomy, and then on confirmation of the diagnosis by lymph node biopsy, by excision of the extranodal deposit with a CO2 bronchoscopic laser.
