Psoriasis is an immune-mediated disease where skin cells multiply too quickly. This rapid life cycle of skin cells results in symptoms affecting the skin, such as scaly and silvery lesions, red patches, and sores filled with pus. Symptoms of psoriasis depend on the type of psoriasis. Inverse psoriasis is a type of psoriasis occurring in the folds of the skin. This immune-mediated inflammatory skin disease causes itchy, scaly patches and plaques to appear, and in skin folds, the plaques may appear shiny.

What Is Inverse Psoriasis?
Inverse psoriasis, also referred to as flexural psoriasis or intertriginous psoriasis, is a form of psoriasis affecting skin areas that rub together like skin folds, such as the groin, armpits, belly button, and skin below the breasts. Inverse psoriasis causes the skin cells to reproduce quicker than the skin can manage. It appears as shiny, smooth, discolored rashes that may be brown, red, or purple. The rashes or plaques may feel damp to the touch. Inverse psoriasis is often called an autoimmune disease, yet the antibody that causes the condition has not yet been identified.
As such, it is categorized as an immune-mediated disease, meaning the exact cause is unknown, but experts believe the cause is the immune system's response. Psoriasis is characterized by the production of thick, discolored patches on the skin covered with white or silvery scales or plaques. In contrast, inverse psoriasis does not feature thick, scaly patches characteristic of other types. This is likely because inverse psoriasis is present in moist body areas. An inverse psoriasis rash also appears shinier than other psoriasis rashes.
Inverse Psoriasis Vs. Intertrigo
Inverse psoriasis and intertrigo are inflammatory skin disease rashes in skin folds. Yet, inverse psoriasis and intertrigo have different causes and treatment options. Intertrigo is caused by skin rubbing against the skin. Moisture becomes trapped in the surfaces of the skin, causing the skin to come together in the skin folds. The moisture increases the level of friction of the skin-to-skin contact, resulting in skin damage and inflammation. Keeping the affected skin clean, dry, and cool can help alleviate the symptoms associated with intertrigo.
In contrast, inverse psoriasis is an immune-mediated disease, meaning the body’s immune system attacks parts of the skin instead of protecting the body from bacteria, viruses, and other foreign invaders. Treatments for inverse psoriasis can help reduce the symptoms of the disease or make them dissipate altogether. However, inverse psoriasis is typically a chronic condition, meaning flare-ups can occur throughout one’s lifetime.
What Does Inverse Psoriasis Look Like?
Inverse psoriasis is known by its presentation as a red, shiny, smooth skin rash. On individuals with darker skin, the rash may appear dark purple, brown, or darker than the surrounding skin. Unlike other forms of psoriasis that produce scales, pustular spots, and crusting skin, inverse psoriasis rashes are not raised nor dry. In fact, inflamed skin patches from inverse psoriasis can feel moist to the touch.
Individuals with this condition may experience irritation, itching, or both in the affected areas. Additionally, individuals with this psoriasis are at risk of developing yeast infections due to the high degree of moisture. The red lesions may cover large areas within the skin folds.
