A case of primary pulmonary botryomycosis by Gemella morbilium / 대한내과학회지

Botryomycosis is a chronic supprative disease with characteristic granules formation in the pus caused by bacteria and frequently is mistaken for a fungal infection. Pulmonary botryomycosis can resemble actinomycosis, tuberculosis, or invasive carcinoma by causing a mass lesion with constitutional symptoms. We report a case of pulmonary botryomycosis in a 43 years old man. He had a cavitary lesion of the right upper lobe and diagnosis was confirmed by percutaneous needle aspiration. The specimen demonstrated multiple clusters of bacteria within abscess that best were visualized by gram staining. Cultures of the biopsy materials yielded pure growth of Gemella morbilium. The patient recovered quickly after antibiotics treatment for 3 weeks.
