Which term refers to a vesicle that is filled with pus?

Pustule
Bulla
Scale
Crust

The correct answer is: Pustule

A pustule is a small, raised, inflamed area of skin that is filled with pus. This term is most commonly used in dermatology to describe lesions that occur during various skin conditions, such as acne, where the accumulation of pus is caused by infection or inflammation. Pustules often appear as white or yellowish bumps surrounded by redness and can be painful or itchy. Understanding this term is essential for identifying and discussing skin lesions in both clinical and educational contexts. In contrast, a bulla is a larger fluid-filled blister that contains clear fluid, a scale refers to flat pieces of skin that flake off, and crust is a hardened layer that forms over a wound or lesion as it dries. These terms represent different types of skin conditions or lesions, differentiating them from the specific characteristics of a pustule.
