Pulmonary Actinomycosis has a strong clinical and radiological resemblance to tuberculosis, lung abscess, and lung cancer, leading to missed or delayed diagnosis. We present a case of an elderly male with a productive cough and weight loss with right upper lobe consolidation on imaging. Definitive diagnosis was by histopathology; drawing samples by fiber-optic bronchoscopy, broncho-alveolar lavage, and endobronchial ultrasound. Tuberculosis, fungal infection, and malignancy were ruled out. Diagnosis was confirmed by demonstration of filamentous colonies of\n                    <jats:italic toggle=\"yes\">Actinomyces<\/jats:italic>\n                    on hematoxylin and eosin and Grocott-Gomori\u2019s methanamine silver stain.
