Psoriasis is a chronic autoimmune condition that primarily affects the skin, causing it to become inflamed, red, and scaly. The condition is not contagious, but it can significantly impact a person's quality of life. The signs of psoriasis can vary depending on the type and severity of the condition. Below, we explore the most common signs and symptoms associated with psoriasis, its different types, and how it compares to other skin conditions.
Common Signs of Psoriasis
One of the most noticeable signs of psoriasis is the appearance of raised, red patches covered with silvery scales. These patches, known as plaques, often develop on the elbows, knees, scalp, and lower back. They can be itchy, painful, and sometimes crack and bleed. Other common signs include:
- Dry, cracked skin that may bleed
- Thickened, pitted, or ridged nails
- Swollen and stiff joints
- Burning or soreness in affected areas
Types of Psoriasis
Psoriasis can present in several forms, each with unique characteristics. The most common types include:
- Plaque Psoriasis: The most prevalent form, characterized by raised, red patches covered with silvery scales.
- Guttate Psoriasis: Often triggered by infections, this type appears as small, dot-like lesions.
- Inverse Psoriasis: Affects skin folds, such as under the arms or breasts, and appears as smooth, red patches.
- Pustular Psoriasis: Causes white pustules surrounded by red skin, often localized to the hands and feet.
- Erythrodermic Psoriasis: A rare and severe form that leads to widespread redness and shedding of the skin.
