Which term describes a small, elevated lesion filled with clear fluid?

The term that describes a small, elevated lesion filled with clear fluid is "vesicle." Vesicles are typically less than 0.5 centimeters in diameter and can appear as small blisters on the skin. They are often associated with conditions such as herpes simplex, chickenpox, or contact dermatitis.

Pustules, in contrast, are lesions that contain pus, making them different from vesicles, which are fluid-filled but not purulent. A patch is a flat area of skin that is altered in color or texture but does not involve elevation or fluid accumulation, whereas a blister can refer more broadly to any bubble-like lesion filled with fluid, which may not specifically indicate the size or clear fluid composition that defines vesicles.

This understanding is essential for correctly identifying skin lesions in clinical practice and ensures appropriate treatment and management.
