Small, white keratin-filled bumps or cysts that are enclosed within the epidermis:

• A. Milia
• B. Comedones
• C. Blackheads
• D. Dry skin

Answer: (A)

Milia are tiny, white keratin-filled cysts that sit just beneath the skin’s surface, enclosed within the epidermis. They form when keratin becomes trapped under the skin, creating small, firm bumps that lack a visible pore. This distinguishes them from other bumps like comedones, which are plugs inside a hair follicle and can be open (blackhead) or closed (whitehead) and involve sebum and keratin. Dry skin isn’t a cystic lesion at all; it’s a moisture deficiency that presents as rough, flaky skin. So the description of small, white keratin-filled bumps enclosed within the epidermis fits milia perfectly.
