ReJUVA Psoriasis

There are many subtypes of psoriasis including plaque, guttate, pustular, erythrodermic, and inverse psoriasis.

Plaque psoriasis is the most common type. These red, scaly, well-circumscribed patches often appear on the flexural skin such as elbows, knees, and scalp, and are often symmetrical. The lesions are covered in a thick white scale. Nail changes are common in psoriasis and include nail pitting, yellowing of the nail, or abnormal separation of the nail plate.

Guttate psoriasis appears as small droplet-like well-circumscribed plaques. Guttate psoriasis appears more rapidly than plaque psoriasis and is often triggered by a streptococcal infection. In some cases, psoriasis may be triggered by medications or trauma. The “koebner phenomenon” describes psoriasis plaques forming in areas of trauma or following surgical incision.

Pustular psoriasis appears as multiple, tiny pustules that may be filled with pus. Pustular psoriasis often appears on the palms and soles and is more acute in onset than plaque psoriasis. These pustules are often very itchy.

Erythrodermic psoriasis is described as a widespread redness covering a large surface area of the body. This rash appears quickly and can be very painful. This is a form of exfoliative dermatitis.

Inverse psoriasis is a common form of psoriasis located in the flexural areas of the body such as the armpits, groin, inframammary folds, and gluteal cleft. Due to the location, these rashes often appear as red plaques without extensive overlying scale. Inverse psoriasis is often misdiagnosed as a fungal rash.
