Introduction to Dermatology

• Dermatology is the branch of medicine specializing in the diagnosis and treatment of skin diseases, disorders, and conditions.
• It covers a wide spectrum of issues, from minor skin irritations to complex inflammatory conditions.
• Dermatologists use a combination of clinical evaluations, diagnostic tests, and therapeutic interventions to address these concerns.

Psoriasis Overview

• Psoriasis is a chronic autoimmune skin condition marked by red, scaly patches on the skin.
• It affects people of all ages, with varying degrees of severity.
• The exact cause remains unclear, but an overactive immune system is implicated.
• Genetic predisposition significantly contributes to psoriasis development.
• Environmental factors, like stress and infections, can trigger or exacerbate the condition in susceptible individuals.

Types of Psoriasis

• Plaque psoriasis is the most common type, featuring raised, red, inflamed skin lesions covered with silvery-white scales.
• Guttate psoriasis presents as small, red spots (drops) spread across the body.
• Inverse psoriasis appears as smooth, red patches in skin folds, such as the groin and armpits.
• Pustular psoriasis involves the formation of pus-filled blisters on the skin.
