What is a small blister or sac containing clear fluid, lying within or just beneath the epidermis called?

Vesicle
Pustule
Macule
Patch

The correct answer is: Vesicle

A small blister or sac containing clear fluid that is located within or just beneath the epidermis is known as a vesicle. Vesicles are typically smaller than 0.5 centimeters in diameter and can occur due to a variety of reasons, including irritation, infection, or allergic reactions. They are an important aspect of dermatological conditions, as their appearance can help in diagnosing various skin issues. In contrast, a pustule is defined as a small elevation of the skin that contains pus, which differs significantly from a vesicle containing clear fluid. A macule is a flat, distinct, discolored area of skin that does not involve a change in the thickness or texture of the skin, which is also distinct from a vesicle. A patch is a larger area of skin discoloration, which can encompass several macules but is not characterized by the presence of fluid-filled sacs. Understanding these terms is essential for identifying the types of lesions and their potential causes in the practice of barbering and skincare.
