Lee SZ, Syed MT, Kumar P. Actinomycosis or malignancy: A diagnostic dilemma. Int J Case Rep Images 2019;10:101055Z01SL2019.ABSTRACT
Introduction: Pulmonary actinomycosis is caused by a chronic inflammatory reaction to an infection by the Actinomyces species and presents as a pulmonary infiltrate or a mass. Thoracic actinomycosis can resemble bronchogenic carcinoma in its clinical presentation and radiographic appearance.
Case Report: In this article, we report a 71-year-old man with pulmonary actinomycosis who presented with an incidental presentation of lung mass on imaging studies, following a respiratory outpatient clinic review of hemoptysis of more than six months. Nonspecific clinical and radiologic presentations make pulmonary actinomycosis difficult to be diagnose and often lead to misinterpretation as malignancy rather than an infective process.
Conclusion: This case was successfully managed with a diagnostic and curative wedge resection of his right upper and middle lung lobes and antibiotics. Penicillin remains the traditional treatment of choice.
Keywords: Lung cancer mimic, Lung nodule, Pulmonary actinomycosis, Recurrent hemoptysis
