What condition results in the buildup of skin cells that form thick, silvery scales?

• A. Impetigo
• B. Psoriasis
• C. Acne
• D. Rosacea

Answer: (B)

The buildup of skin cells that forms thick, silvery scales is characteristic of psoriasis. This chronic autoimmune condition prompts an accelerated skin cell production cycle, causing cells to accumulate on the skin's surface and leading to raised, red patches covered with a silvery-white appearance.

In psoriasis, the immune system mistakenly signals skin cells to replicate at a faster rate than normal, which does not allow enough time for the old cells to slough off. As a result, these cells pile up and manifest as the distinctive scales often seen on the elbows, knees, and scalp. This accumulation can lead to significant discomfort, itching, and potential for further skin issues.

Other listed conditions do not produce the same type of skin presentation. Impetigo is a bacterial infection that typically results in blisters and sores rather than scaling. Acne involves the blockage of hair follicles and the formation of pimples and does not lead to the thick scaling associated with psoriasis. Rosacea is a chronic skin condition characterized primarily by facial redness and does not involve silvery scales but rather flushing and sometimes acne-like breakouts.
