Dermatology

The Department of Dermatology is the medical specialty dedicated to the diagnosis and treatment of conditions affecting the skin, hair, nails, and mucous membranes. As the body's largest organ, the skin serves as a protective barrier against environmental threats, regulates temperature, and provides sensory information.

Dermatologists manage an extensive range of conditions. Common issues include acne, which affects millions worldwide; eczema and psoriasis, chronic inflammatory conditions causing red, scaly patches; and skin infections caused by bacteria, viruses, or fungi. They also treat rosacea, causing facial redness; allergic skin reactions; and benign growths like warts and moles.

Skin cancer is a major focus of dermatology. The three main types are basal cell carcinoma, squamous cell carcinoma, and melanoma, the most dangerous form. Dermatologists perform regular skin cancer screenings and suspicious lesions may be biopsied. Early detection is crucial for successful treatment.

Diagnosis relies heavily on visual examination. Dermatologists often use dermatoscopy, a handheld magnifying device with a light, to examine skin lesions more closely. When needed, skin biopsies are performed, taking small tissue samples for laboratory analysis. Patch testing helps identify allergens causing contact dermatitis.

Treatment approaches vary widely. Topical medications including creams and ointments treat many surface conditions. Systemic medications such as antibiotics or immunosuppressants address more severe diseases. Procedural dermatology includes cryotherapy freezing warts, laser therapy, phototherapy using ultraviolet light, and minor surgeries for skin cancer removal. Modern dermatology also includes cosmetic procedures. The goal is to maintain healthy skin, treat diseases promptly, and detect skin cancer at its earliest, most treatable stage.
