The color of the skin. 1. Hypomelanosis.

Abstract

Diseases of very different severity and fre­quency are included in this chapter. Ash-leaf­shaped hypomelanotic macules of tuberous sclerosis are rare. However, they are often the earliest sign of the disease. Vitiligo is less rare and is important due to esthetic and psychological reasons. After puberty hypo­chromic pityriasis versicolor is very frequent. However, it practically does not exist in chil­dren. Hypochromic sequelae of traumas or other dermatoses, mainly atopic dermatitis, are most frequent in children, especially in summer and autumn. (...).
