For a professional who specializes in treating skin diseases, which term is correct?

• A. Dermatologist
• B. Oncologist
• C. Nephrologist
• D. Psychiatrist

Answer: (A)

The key idea is identifying the medical specialty that focuses on the skin. A dermatologist is a physician with specialized training in dermatology who diagnoses and treats conditions of the skin, hair, and nails. They handle issues such as acne, eczema, psoriasis, dermatitis, fungal infections, and skin cancers, and they may perform biopsies or skin-related procedures. The other listed specialists focus on different areas: an oncologist treats cancer, including skin cancer, but not exclusively; a nephrologist treats kidney diseases; a psychiatrist treats mental health conditions. Therefore, the term that best describes someone who specializes in treating skin diseases is dermatologist.
