Enfermedad de Rosai-Dorfman con compromiso laríngeo: A propósito de un caso

Abstract

ABSTRACT Rosai-Dorfman disease or sinus histiocytosis with massive lymphadenopathy is a rare disease of unknown etiology characterized by bilateral massive cervical lymphadenopathy. Extranodal involvement can occur in different sites including airway where nasosinusal involvement is common but this disease may occur in other sites of the upper airway. Laryngeal involvement is rare. We present the case of an 82-year-old female patient with a history of Rosai-Dorfman disease located in cervical lymph nodes in spontaneous remission that subsequently develops airway obstruction. Computed tomographic scan and nasopharyngolaryngoscopy showed subglottic lessons that severely obstructed the airway. Emergency tracheotomy and biopsy were performed, confirming the diagnosis of extranodal RDD. Patient was observed and tracheostomy was maintained with good tolerance.
