A case is reported in a 55-year-old man from the Netherlands , who presented with progressive pain on the left hemithorax. A mass in the left upper lobe was seen on the chest radiograph. Computed tomography showed mediastinal lymphadenopathy and a mass in the left upper lobe with invasion of the chest wall. The results of all cytological and microbiological examinations were normal. The clinical diagnosis was bronchial carcinoma. A PET scan showed enhanced uptake within the left chest wall without mediastinal lymphadenopathy. At that stage, the left hemithorax had become indurated. Microbiological examination of pus showed Gram positive anaerobic organisms consistent with Actinomyces, and a clinical diagnosis of actinomycosis was made.
