Which of the following skin disorders is likely to result from the localized lack of melanin production by melanocytes?
A) Rash
B) Bullae
C) Vitiligo
D) Melasma
Ans: C
Feedback:
In cases of vitiligo, depigmented areas may contain no melanocytes, greatly altered or decreased amounts of melanocytes, or, in some cases, melanocytes that no longer produce melanin. Melasma results from increased pigmentation, and neither bullae nor rashes are consequences of alteration in melanocyte function.
