Inverse second

Inverse psoriasis (also known as intertriginous psoriasis) is a form of psoriasis that affects skin folds. Unlike the more common plaque psoriasis, inverse psoriasis is characterized by smooth patches of red, inflamed skin. It is more prevalent in individuals who are overweight or have deep skin folds. Areas often affected include the armpits, groin, under the breasts, and other folds around the genitals and buttocks. Inverse psoriasis can be particularly uncomfortable due to its location in sensitive and moist areas, where friction and sweating may exacerbate the condition.

Causes and Risk Factors

The exact cause of inverse psoriasis is unknown, but it is believed to be related to the immune system and is triggered by factors similar to those of other types of psoriasis. These can include genetic predisposition, stress, skin injuries, and certain medications. Conditions that increase skin friction and moisture, such as obesity, can also contribute to the development of inverse psoriasis.

Symptoms

Symptoms of inverse psoriasis include smooth, bright red patches in the skin folds. These patches may be painful or itchy and are prone to worsening with friction and sweating. Unlike plaque psoriasis, scales are typically not observed due to the moist environment of the affected areas.

Diagnosis

Diagnosis of inverse psoriasis is primarily clinical, based on the appearance of the skin lesions and their locations. A healthcare provider may also perform a biopsy to rule out other conditions, such as fungal infections, which can appear similar.

Treatment

Treatment for inverse psoriasis aims to reduce inflammation and discomfort. Options include topical steroids, which must be used with caution in sensitive areas, and non-steroidal medications like calcineurin inhibitors. In more severe cases, systemic treatments such as biologics or phototherapy may be recommended. Managing contributing factors, such as obesity, can also help control symptoms.

Living with Inverse Psoriasis

Living with inverse psoriasis can be challenging due to the discomfort and potential for embarrassment. However, with proper management and care, individuals can lead a healthy lifestyle. It is important for patients to follow their treatment plan and maintain good hygiene practices to minimize discomfort and prevent flare-ups.
