Özet

ABSTRACT Actinomycosis is a chronic, suppurative infection caused by Actinomyces israelii, an anaerobic bacterium that is part of the normal oral flora. A 47-year-old woman presented to the clinic with dyspnea and sore throat. Computed tomography(CT) revealed thickening of the proximal tracheal lumen and airway narrowing. Pathological examination of biopsy specimens obtained by rigid bronchoscopy revealed periodic acid-Schiff (PAS)(+) bacterial colonization with filamentous bacilli, consistent with Actinomyces. This report describes an uncommon presentation of tracheal actinomycosis in which tracheal dilatation was performed for both diagnostic sampling and therapeutic management of tracheal stenosis.
