Psoriasis can affect many parts of the body including the skin, scalp and nails. Any area of the skin can be affected, including skin on the pubic, anal and genital areas. The cause of genial psoriasis is unknown, but a combination of genetic, dietary and environmental factors come into play. Skin irritants and allergens can frequently worsen psoriasis in the genital area.

All areas of the genitals and the surrounding area can be affected by psoriasis.

This includes areas such as-

The buttocks and crease

Psoriasis affects this area more frequently than you may imagine. It can present as red patches with or without scale. In some people it can be very itchy, whilst in others, it is asymptomatic.


Psoriasis of the vulval areas can present as smooth red areas, or scaly patches. If itching develops, then the areas maybe thickened and dry.

The area between the belly button and genital areas is known as the pubis, and is a commonly affected area for psoriasis patients. Psoriasis in this areas responds well to a mixture of creams and phototherapy. In some patients dietary changes can make a significant difference.

Psoriasis affecting this area can be difficult to diagnose and may present as red patches. This area is prone to irritation and itch, and maybe confused with haemorrhoids, fungal infections or pin worm infections. Treatments for psoriasis affecting the anal area including removing dietary triggers, irritants and allergens and protecting the surrounding anal skin.

Steroid creams can be used for very short periods. We generally prefer to avoid steroid creams in this area, but they maybe used to control psoriasis in the short term.
