Psoriasis
The Correct Answer is B
A. Keratosis pilaris:
This is a condition of small, rough bumps typically on arms or thighs, not depigmentation.
B. Vitiligo:
Vitiligo is a condition where melanocytes are destroyed, leading to depigmented patches of skin, especially in sun-exposed areas.
C. Rosacea:
Rosacea is characterized by facial redness, flushing, and visible blood vessels, not loss of pigment.
D. Psoriasis:
Psoriasis involves scaly, red plaques due to rapid skin cell turnover, not loss of melanocytes.
