Psoriasis is a chronic autoimmune skin disorder characterized by accelerated skin cell turnover, leading to thickened, scaly plaques and persistent inflammation. It commonly affects the scalp, elbows, knees, lower back, and nails, though it may involve any part of the body. Psoriasis is a systemic inflammatory condition and may be associated with joint involvement and metabolic disorders.

Triggers include genetic predisposition, stress, infections, skin trauma, and environmental factors. The disease follows a relapsing-remitting course, with periods of flare and remission. Symptoms may range from mild localized plaques to extensive skin involvement affecting daily functioning.

Psoriasis can significantly impact physical comfort, self-image, and emotional health. Nail changes, scalp involvement, and visible plaques often contribute to social and psychological distress.

Dermatological management focuses on disease severity assessment, trigger identification, and individualized treatment planning. Long-term care aims to control inflammation, reduce plaque thickness, relieve symptoms, and prevent progression.

Psoriasis requires ongoing monitoring due to its chronic nature and potential systemic associations. Early diagnosis and structured dermatological care improve symptom control and long-term outcomes.
