What do pustules contain?

• A. A small collection of blood
• B. A collection of pus
• C. Fluid
• D. Air

Answer: (B)

Pustules are defined as small, raised lesions on the skin that are filled with pus. The presence of pus is what characterizes pustules, distinguishing them from other types of skin lesions, such as vesicles or blisters, which typically contain clear fluid. Pus itself is a thick fluid that consists of dead white blood cells, bacteria, and tissue debris, and it forms as a response to infection or inflammation. Therefore, recognizing that pustules specifically contain this collection of pus is crucial for understanding their nature and the underlying processes that lead to their formation in various dermatological concerns.
