Inverse Psoriasis vs. Intertrigo

Intertrigo and inverse psoriasis are skin conditions that cause discomfort in areas of the body where the skin folds, such as the groin, armpits, and the abdomen. While psoriasis can be easily confused with other allergy symptoms, inverse psoriasis triggers and treatments are different from intertrigo.

Psoriasis is an autoimmune disease that causes the skin cells to rapidly grow, which leads to a buildup of red, itchy patches on the skin. Inverse psoriasis, also known as intertriginous or flexural psoriasis, is a type of psoriasis that does not appear as scaly as in other types of psoriasis. It is also a persistent or chronic condition, which means that treatments may be able to reduce and eliminate the symptoms for a time. but they can eventually return.

Intertrigo, on the other hand, is not an autoimmune condition. It mainly affects the top layers of the skin. In individuals with this type of condition, the areas get more irritated and itchy when skin-on-skin friction in moist and warm areas occur. The skin usually becomes pink, red or brown. Does intertrigo smell? Yes, especially if it becomes really moist.

Diagnosis

These two conditions can be diagnosed by examining the person’s skin and lesions. But sometimes, doctors order a skin biopsy, a simple test called a KOH exam, which is done to check whether a fungus is causing the symptoms. This test involves scraping a small portion of the skin with a blade and the sample is then run under the microscope for further examination. Doctors may also perform a Wood lamp skin examination, to check if bacteria is causing the symptoms. However, instead of examining it under the microscope, the doctor uses an ultraviolet light over the affected skin area.

Risk Factors

Psoriasis is not contagious, but if you have a family history of the disease, you are more likely to get it. It is also more common among people who are overweight or those who gave deep skin folds. Individuals with a weakened immune system are also more likely to develop this condition.

Since skin rubbing is the main cause of intertrigo, anyone can get it. It is not contagious but there is increased risk among people with diabetes, those who are regularly exposed to heat and high humidity, individuals with artificial limbs, braces, or splints that rub on their skin, those with poor hygiene, and people who are malnourished.

When to see the doctor

Self-diagnosis won’t get you nowhere near any relief or treatment. If you develop an unusual or unexplained rash that won’t go away or is getting worse, see a doctor immediately. Early treatment will help clear it up and lessen the chance or infection.

Inverse psoriasis has no cure, but doctors usually prescribe topical ointments or steroids to lessen the itch and dryness. In severe cases however, ultraviolet B or UBV light therapy or a biologic medication may be needed or advised by the doctor.

Since intertrigo affects the surface of the skin, doctors may prescribe barrier creams or powders to absorb moisture, and sometimes, prescription strength topical creams. They may even advise to wear clothing that will not further irritate your skin (both psoriasis and intertrigo). Wearing underwear, tops, and bottoms made from 100% natural cotton fabric will help relieve some of the symptoms. They are not just safe for people with skin sensitivities, they are also safe for the environment.

Managing the symptoms of both conditions can be easy with the help and advice of a professional. But always remember that observing proper hygiene makes a huge difference when it comes to managing allergy symptoms and other sensitivities.
