What is the name for blisters or sacs filled with fluid?

• A. Macules
• B. Vesicles
• C. Pustules
• D. Wheals

Answer: (B)

Vesicles refer to small blisters or sacs that are filled with fluid, typically found beneath the skin. They can result from various conditions, including infections, allergic reactions, or skin irritations. The fluid within a vesicle can be clear, and the structure is generally small, often less than 1 centimeter in diameter. Understanding vesicles is essential in the context of medical conditions like chickenpox or herpes simplex virus infections, where such fluid-filled sacs can be prominent. This differentiation is significant because it helps health care professionals recognize and diagnose various dermatological conditions based on the forms and characteristics of skin lesions. While macules are flat, discolored spots on the skin without elevation, pustules are similar but contain pus rather than clear fluid. Wheals, on the other hand, are raised, itchy areas caused by localized swelling, often seen in allergic reactions. Being able to identify and understand vesicles in clinical practice can aid in providing appropriate treatment and management of skin-related issues.
