Secondary syphilis clinically mimicking pseudolymphoma of the face.

Syphilis has been given titles such as the great imitator, the great mimic, and the great masquerader. It may lack pathognomonic signs and often presents similar to many other dermatological conditions. We present a case of a young woman who developed asymptomatic papulonodular lesions on the forehead; the lesions were clinically similar to pseudolymphoma but it was determined that she had secondary syphilis exhibiting prozone phenomenon. She also had alopecia of eyebrows. Both the alopecia as well as nodular lesions clinically resembling pseudolymphoma responded to and completely recovered with antisyphilitic treatment.
