Psoriasis is a common chronic autoimmune skin disease that speeds up the growth cycle of skin cells, leading to a buildup of dead cells on the surface of the epidermis. The disease most commonly manifests on the skin of the elbows, knees, scalp, lumbosacral areas, intergluteal clefts, and glans penis. In up to 30% of patients, the joints are also affected. Psoriasis can be confused with other skin diseases (like eczema).
