Psoriasis is a skin disease that develops when the immune system (specifically, one key cell called a T cell) sends faulty signals that ultimately tell skin cells to grow too quickly. Since the body does not shed these excess skin cells quickly enough, the skin cells pile up on the surface of the skin, causing patches of psoriasis to appear.
How Psoriasis Develops
There are different types of Psoriasis, each with their own symptoms. First, let’s look at how Psoriasis develops and affects the skin. As stated, with Psoriasis, the cycle of the skin cells is accelerated, resulting in a buildup of dead cells on the surface, causing patches of Psoriasis.
Plaque Psoriasis
Plaque Psoriasis – the most common type of Psoriasis. It usually causes dry, red skin lesions (plaques) covered with silvery scales.
Guttate Psoriasis
Guttate Psoriasis – this type of Psoriasis is more common in children and adults under 30. It appears as small, water-drop-shaped sores on the trunk, arms, legs and scalp. The sores are typically covered by a fine scale.
Scalp Psoriasis
Scalp Psoriasis – this type of Psoriasis causes red patches of skin covered with silvery scales and a thick crust on the scalp that may bleed when removed.
Inverse Psoriasis
Inverse Psoriasis - this form of Psoriasis causes smooth patches of red, inflamed skin wherever there is skin touching skin – it’s one reason why this type of Psoriasis is common in overweight people. It is worsened by friction and sweating.
Pustular Psoriasis
Pustular Psoriasis – this type of Psoriasis generally develops quickly, with pus-filled blisters appearing just hours after your skin becomes red and tender. It can occur in widespread patches or in smaller areas on your hands, feet or fingertips.
Nummular Psoriasis
Nummular Psoriasis – In contrast to the drop-like patches of Guttate psoriasis, Nummular psoriasis is characterized by round plaques which are about the size and shape of a coin.
Nail Psoriasis
Nail Psoriasis – this can affect fingernails and toenails, causing pitting, abnormal nail growth and discoloration.
Erythrodermic Psoriasis
Erythrodermic Psoriais – this is the least common type of psoriasis and can cover your entire body with a red, peeling rash that can itch or burn intensely.
