ABSTRACT
Abstract We present a case of atypical presentation of secondary syphilis with extensive lymph node involvement and pulmonary lesions, initially suspected as lymphoma. The patient presented with weight loss, dry cough, chest pain, palpable lymph nodes in several peripheral chains, and multiple pulmonary nodules and masses on chest imaging. The key features for secondary syphilis diagnosis were a lymph node biopsy suggestive of reactive lymphadenopathy, positive serologic tests for syphilis, and complete recovery after antisyphilitic treatment.

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.
