- AContact Dermatitis
- BIchthyosis Vulgaris
- CPsoriasis
- DEczema (Atopic Dermatitis)
Show answer & explanationAnswer & explanation
Correct answer: B. Ichthyosis Vulgaris
Ichthyosis Vulgaris is characterized by persistent dry, scaly skin that resembles fish scales, often worsening in dry, cold conditions. Consistent moisturization and gentle exfoliation are key management strategies. The other options describe different skin conditions.
Why the other options are wrong
- A. Contact dermatitis is an inflammatory reaction to an irritant or allergen, not a genetic scaling disorder.
- C. Psoriasis presents with thick, silvery scales on red patches, distinct from the generalized dryness and scaling of ichthyosis.
- D. Eczema involves inflamed, itchy patches, but typically not the distinct fish-scale appearance.

Memory trick: Imagine a fish out of water, dry and scaly, needing moisture.
