Plaque psoriasis is the most common form of psoriasis. The main areas affected by plaque psoriasis are the areas subject to friction, especially the elbows, knees, legs and arms. But plaque psoriasis can also affect the back and buttocks, most commonly the lower back (or upper part of the buttocks).
Summary
This is the lumbosacral region, an area affected by psoriasis, which is subject to constant rubbing caused by clothing and everyday activities, such as carrying a backpack. Patients often scratch all the time, and for a long time, sometimes without even realizing it, and therefore, are unaware of the damage it is causing to the plaques. Scratching makes the lesions worse.
With psoriasis on the back and buttocks, the plaques cannot be seen by others, but this does not stop psoriasis patients from developing a complex. The scales can quickly fall off and make clothes look dirty, especially those in darker colors.
And what should patients do when the sun comes out and the weather gets hotter? Putting on a swimsuit to reveal a back covered with plaques is difficult or even impossible for some. So, you keep your T-shirt on or tie a sarong around your waist, anything to avoid showing the tiniest bit of skin.
Another form of buttock psoriasis specifically affects the intergluteal skin fold: this is inverse psoriasis, also known as skin-fold psoriasis.
The plaques are red, and most often do not have scales. The condition can cause a lot of embarrassment, particularly in sexual relationships. Patients fear showing their bodies to others, they worry the other person will be disgusted, or will confuse the condition with a sexually transmitted infection (STI). All this can lower patients' sex drive and cause relationship problems. If necessary, talk to a healthcare professional whom you trust.
