Which type of skin lesion is raised and filled with pus?

• A. Vesicle
• B. Pustule
• C. Macule
• D. Scale

Answer: (B)

A pustule is a type of skin lesion that is characterized by its raised appearance and is filled with pus. Pustules are small bumps on the skin that contain a mixture of dead white blood cells, bacteria, and other debris, resulting from inflammation or infection. This pus makes pustules distinct, as they typically appear white or yellow at the top, indicating they are filled with this purulent material. In contrast, a vesicle is also a raised lesion but is filled with clear fluid rather than pus. Macules are flat, discolored areas of the skin that do not have any elevation or fluid, while scales refer to the shedding of dead skin cells and are not raised lesions filled with any substance. These characteristics help in distinguishing a pustule from the other types of lesions listed, confirming its unique nature in dermatological conditions.
