Answer

Syphilis, an STD that commonly occurs in sexually active young adults, can also produce a rash, symptoms of arthritis, and genital lesions. However, genital involvement is usually in the form of an ulcer and not urethritis, and the rash can involve the palms and the soles. Laboratory tests, including rapid plasma reagin (RPR) titers, can aid in distinguishing syphilis from gonococcemia.
