What is Leukoderma?

  1. A congenital disorder causing lack of skin pigmentation due to decreased melanocyte activity

  2. An acquired disorder with loss of pigment in melanin cells

  3. A disorder resulting from skin trauma causing dark patches

  4. Increased pigmentation in pregnant women

The correct answer is: A congenital disorder causing lack of skin pigmentation due to decreased melanocyte activity

Leukoderma is a medical condition characterized by a lack of pigmentation in the skin. This can be caused by a decrease in the activity of melanocyte cells, which are responsible for producing skin pigment. Option B is incorrect because leukoderma is not an acquired disorder, but rather a congenital one. Option C is incorrect because leukoderma is not caused by trauma, and option D is incorrect because leukoderma does not result in increased pigmentation.
