What do you call sacs filled with pus on the skin?

• A. Papules
• B. Pustules
• C. Crusts
• D. Vesicles

Answer: (B)

The term for sacs filled with pus on the skin is "pustules." Pustules are small, raised lesions that contain purulent material, which is typically yellowish or white and indicates the presence of infection or inflammation. They can appear in various skin conditions, such as acne or folliculitis, and are characterized by their combination of redness, swelling, and the presence of pus. Understanding the characteristics of other terms is helpful in differentiating them from pustules. Papules are solid, raised bumps that are usually less than 1 cm in diameter and do not contain any fluid. Crusts refer to dried exudate on the skin, often resulting from the healing of a wound or a dermatological condition, but they do not denote pus-filled sacs. Vesicles are small fluid-filled blisters that are typically clear, not containing pus, and they form as a response to infection or irritants. Each of these terms describes distinct types of skin lesions, emphasizing the importance of precise language in medical terminology.
