What disease should genital warts be distinguished from?

 Latent infection can be confirmed by in situ hybridization or polymerase chain reaction (PCR). Common diseases that need to be distinguished include the following:

 Flat genital warts: They are flat, moist papules that are often fused and have a non-narrow base. Treponema pallidum can be found and syphilis serology is positive.

 Vulvar pseudocondyloma: Also known as genital wart-like papules on the vulva, it is more common in young adults. The rash is located on the inner side of the labia minora on both sides. It is a cluster of small caviar-shaped or polyp-shaped papules that do not merge. They feel granular or soft to the touch, are light red, and are moist. They generally have no symptoms, and some have mild itching.

 Pearly papules on penis: Most common in young adults, they are pearly translucent papules on the coronal sulcus, white, light yellow or red, conical, spherical or irregular in shape, arranged in one or several rows along the coronal sulcus, or even in a circle, without obvious symptoms.

 Bowenoid papulosis: The rash is often composed of multiple pigmented papules, which can also appear singly, scattered or clustered, arranged in a linear or circular pattern, and can fuse into plaques in severe cases and develop slowly (months or years). The disease is squamous cell carcinoma in situ or develops from genital warts. primary disease female Slightly more, mainly distributed in the labia majora and perianal area.

 Sebaceous gland hyperplasia: Pale yellow papules, sessile, no spines, no overlap, no fusion.

 Sebaceous heterotopia: The papules grow within the mucous membrane without overlapping, and are mostly light yellow.

 Parafrenal gland hyperplasia: There are skin-colored or light red papules arranged in pairs on both sides of the foreskin frenulum, and some have mild spines on the surface. The base of the papules is not narrow, with large milia or needles, and no obvious symptoms. 【Jilin City skin disease Hospital Lin Taosheng]
