Psoriasis is thought to be an immune system problem. Triggers include infections, stress and cold.
The most common symptom is a rash on the skin, but sometimes the rash involves the nails or joints.
Treatment aims to remove scales and stop skin cells from growing so quickly. Topical ointments, light therapy and medication can offer relief.
