A 32-year-old man presents with complaints of a 1-week history of multiple painful vesicles on the shaft of his penis associated with tender groin adenopathy (Figure 135-1). The vesicles broke 2 days ago and the pain has increased. He had similar lesions 1 year ago but never went for a healthcare examination at that time. He has had 3 different female sexual partners in the past 2 years but has no knowledge of them having any sores or diseases. He was given the presumptive diagnosis of genital herpes and a course of acyclovir. His herpes polymerase chain reaction (PCR) came back positive, and his rapid plasma reagin (RPR) and HIV tests were negative.

Herpes simplex virus (HSV) infection can involve the skin, mucosa, eyes, and central nervous system. HSV establishes a latent state followed by viral reactivation and recurrent local disease. Perinatal transmission of HSV can lead to significant fetal morbidity and mortality.
HSV affects more than one-third of the world's population, with the 2 most common cutaneous manifestations being genital (Figures 135-1, 135-2, 135-3, 135-4) and orolabial herpes (Figures 135-5, 135-6, 135-7).1
