Syphilis is an infectious systemic disease caused by Treponema pallidum. A case of secondary syphilis in a 37- year-old man with respiratory complaints is reported. Clinical manifestations and imaging exams, including chest radiographs and CT, suggested neoplasm. Dermatological examination and skin biopsy, along with serologic testing, were performed and confirmed the diagnosis of syphilis. The patient was treated with weekly intramuscular injections of 24.000.00 IU of benzathine penicillin for two consecutive weeks. His symptoms and skin lesions disappeared, serological tests negativated and the regression of the radiological abnormalities was observed.
