We describe the presentation of a 72-year-old woman with concurrent diagnoses of lung adenocarcinoma in conjunction with disseminated Actinomyces meyeri infection; a rare pathogen which can mimic lung cancer both symptomatically and radiologically. The patient was found to have a pelvic mass initially presumed to be cervical metastases-later confirmed to be of xanthogranulomatous inflammatory origin following transvaginal ultrasound-guided biopsy. The pathogenic cause, identified following pleural aspirate, being a fully sensitive A. meyeri infection; treated with prolonged course amoxicillin.
