Abstract We present a case involving a 74-year-old woman with cat scratch disease characterized by an enlarged and hard axillary lymph node as well as a palpable breast nodule mimicking a carcinoma. The lymph node and the breast nodule were excised. The pathologic examinations revealed granulomatous lymphadenitis with gram-negative bacilli and an intraductal papilloma. Antibiotic therapy (azithromycin) was prescribed and the patient’s clinical evolution was excellent.
