Pulmonary Actinomycosis: A Case Report

Abstract

Pulmonary actinomycosis is a bacterial disease caused by actinomyces species with nonspecific clinical and radiologic findings that make it difficult to diagnose, and that is mistaken for malignancy. We present here the case of 29-year-old woman who was admitted to our hospital with a cough that had been intermittently worsening for the last 3 years, and who was diagnosed with pulmonary actinomycosis based on transbronchial biopsy, despite the absence of bronchoscopic lesions.
