Deciphering the Mystery Behind Plaque Psoriasis Skin Rash

Plaque psoriasis is a long-lasting autoimmune condition that causes raised, red patches on the skin covered with silvery white scales of dead skin cells. These patches, or plaques, can show up on any part of the body, but are most often found on the elbows, knees, scalp, and lower back. While the precise cause of plaque psoriasis remains unclear, it is thought to stem from an immune system malfunction that prompts rapid skin cell growth. This overgrowth leads to the formation of thick, scaly patches characteristic of the condition.
