Which medical field specializes in diseases and conditions of the skin?

• A. Dermatology
• B. Gastroenterology
• C. Pulmonology
• D. Nephrology

Answer: (A)

Recognizing which medical field focuses on the organ system involved is what this item tests. Dermatology is the branch that specializes in the skin, its diseases, and related structures like hair and nails. A dermatologist treats conditions such as acne, eczema, psoriasis, dermatitis, and skin cancers, and can perform procedures tied to skin health. The other listed fields focus on different body systems—gastroenterology on the digestive tract, pulmonology on the lungs, and nephrology on the kidneys—so they aren’t about skin disorders.
