Show answer & explanationAnswer & explanation
Correct answer: A. Psoriasis of the Scalp
Psoriasis of the scalp is a chronic autoimmune condition characterized by thick, silvery scales, redness, and itching. It is not contagious.
Why the other options are wrong
- B. Tinea capitis is a fungal infection (ringworm) of the scalp, which is highly contagious and typically presents with patchy hair loss and scaling, but usually not silvery scales.
- C. Pediculosis capitis (head lice) involves intense itching and visible nits/lice, not silvery scales.
- D. Seborrheic dermatitis (dandruff) presents with oily, yellowish scales and redness, often with itching, but not typically silvery scales or as thick as psoriasis.
