What type of lesion is typically associated with acne?

Pustules are the correct answer because they are one of the most common types of lesions associated with acne. These lesions can be identified by their characteristic appearance, which includes a raised, inflamed red base with a white or yellow center filled with pus. This pus indicates an accumulation of dead white blood cells, bacteria, and debris, which is a direct result of the inflammatory process that occurs in the skin due to the overproduction of sebum and blockage of hair follicles.

In the context of acne, pustules are often considered a more severe form of acne lesions, reflecting ongoing inflammation and infection. While cysts can also appear in acne cases, they are typically deeper and more painful than pustules. Macules and vesicles do not generally relate directly to acne; macules are flat, discolored spots on the skin, and vesicles are small fluid-filled sacs, neither of which exhibit the inflammatory characteristics associated with acne lesions like pustules do.
