Step-by-step explanation:
During the secondary stage of syphilis, a rash appears on the skin and mucous membranes. The rash typically starts on the palms of the hands or the soles of the feet and then spreads to the trunk and limbs. It can take various forms, such as macular or papular, and may also manifest as mucus patches or wartlike lesions called condylomata lata on mucous membranes.
The rash is accompanied by other symptoms like malaise, fever, and lymph node swelling. The secondary stage of syphilis is highly contagious and lasts for about two to six weeks, with recurrence in approximately 25% of cases.
