What is the presentation of psoriasis?

Psoriasis has a very wide array of presentation. It may manifest as a minor amount of white flakes on the scalp, to pink patches with white scales on the elbows, to a few well-demarcated red scaling plaques on the extremities and lower back, to involving vast surface area with such plaques. Being itchy is the most common symptom of psoriasis. Psoriasis may cause joint pain, which in that case it should be treated before it induces irreversible joint alterations and damage.

Like most medical abnormalities, psoriasis is a multi-factorial condition. Currently, the primary culprits are known to be certain immune cells that home within the epidermis and dermis. These immune cells release substances that make the skin cells, i.e., the epidermal cells, behave differently. In psoriasis the epidermis contains more layers of the epidermal cells, and the dead layer of it. There might be some specific aberration in the epidermal cells, or the substances they produce that triggers the immune cells.
