Final answer:
The patient's symptoms of macules and papules that are bilateral, symmetrical, and appear on the trunk, palms, and soles suggest secondary syphilis. Syphilis is identified by such lesions, particularly on the palms and soles, and requires serological testing for diagnosis. Migrants and urticaria, although mentioned, are terms more commonly associated with other conditions.
Step-by-step explanation:
Based on the description of macules and papules that are round to oval, pink, brown or reddish, bilateral, symmetrical, with the first exanthem being macular and later eruptions more papulesquamous, and their presence on the trunk, palms, and soles, the patient's condition appears to match the clinical presentation of syphilis. Particularly, this description is consistent with secondary syphilis, where such skin lesions are commonly observed. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. The dark lesions on the palms and soles are particularly indicative of secondary syphilis. The differential diagnosis could include other skin conditions like psoriasis, dermatitis, or drug-related eruptions. However, the characteristic presentation on the palms and soles strongly suggests syphilis. A definitive diagnosis would require serological testing. It's important to note that other symptoms may present with syphilis, including migrans (a wandering rash that advances across skin areas), but this term is more commonly associated with Lyme disease. Urticaria, meanwhile, refers to hives and is not directly related to syphilis.
