A Case of Adult Membranous Croup Caused by Methicillin-Resistant Staphylococcus Aureus Mimicking Laryngeal Diphtheria / 대한이비인후과학회지

ABSTRACT

Membranous croup is a rare disease that is characterized by diffuse inflammation of the larynx, trachea, and bronchi with adherent or semiadherent mucopurulent membranes in the subglottic trachea and larynx. All cases have occurred in children and there has been no case of adults. The clinical signs, symptoms, progress and prognosis of membranous croup are more severe than those of ordinary croup. The detached membrane in membranous croup may cause a high degree of air way obstruction and give similar characteristics of laryngeal diphtheria, thus it is important to differentiate it from diphtheria by identifying the pathogen. Herein we report with a review of literature a rare case of adult membranous croup caused by methicillin-resistant staphylococcus aureus mimicking laryngeal diphtheria.
