An example disease associated with pustules is:

• A. Psoriasis
• B. Chicken pox
• C. Burn/blister
• D. Acne, folliculitis

Answer: (D)

Pustules are small, raised lesions filled with pus, produced by neutrophilic inflammation in the epidermis or around hair follicles. Acne and folliculitis are classic examples that routinely present with pustules: in acne, inflammation within the sebaceous follicle leads to pus-containing papules and pustules as the lesion progresses; in folliculitis, infection or irritation of a hair follicle triggers pus-filled centers around the follicle.

Treating the other options as a contrast helps: psoriasis typically shows well‑defined, scaly plaques rather than pus-filled lesions; burns create blisters that are fluid-filled rather than pus-filled; chickenpox lesions are primarily vesicular (fluid-filled) and only later may crust, not centrally pustular in the classic sense.

Thus, acne and folliculitis best fit the description of pustule-forming skin disease.
