What type of skin lesion is a raised area filled with clear fluid?

• A. Bulla
• B. Vesicle
• C. Wart
• D. Fissure

Answer: (B)

A raised area filled with clear fluid is known as a vesicle. Vesicles are small, fluid-filled blisters that can develop on the skin as a result of various conditions, including infections, allergies, or friction. They typically measure less than 0.5 centimeters in diameter and contain serous fluid, which is clear and can be seen through the thin layer of skin. Bulla, which might seem similar, refers to a larger blister that is typically greater than 0.5 centimeters. While both vesicles and bullae are types of fluid-filled lesions, the specific size distinction makes vesicle the correct answer for this question. Other options like warts, which are caused by the human papillomavirus and characterized by rough, raised surfaces, and fissures, which are cracks or splits in the skin, do not describe fluid-filled lesions.
