What is the appearance of seborrheic dermatitis?

• A. Red with white scales
• B. Dark and scaly patches
• C. Patches of dry, flaky skin
• D. Red and itchy bumps

Answer: (A)

Seborrheic dermatitis is characterized by its distinct appearance, which typically includes red skin covered with white or yellowish scales. This condition often occurs in areas rich in sebaceous (oil) glands, such as the scalp, face, and other body parts. The redness indicates inflammation, and the scaling can be quite visible, often resembling dandruff when it occurs on the scalp. The other options highlight features associated with different skin conditions. Dark and scaly patches may refer to conditions like lichen planus or psoriasis, while patches of dry, flaky skin could be a general description applicable to various dermatological issues but do not specify the characteristic redness associated with seborrheic dermatitis. Red and itchy bumps might imply hives or another type of allergic reaction rather than the scaling and inflammation that define seborrheic dermatitis.
