This text atlas addresses problems raised by the fact that dermatological conditions present quite differently in populations of different ethnic origin and skins of different pigmentation. Thus, on the one hand, Western doctors working in tropical communities have difficulty in diagnosing even tropical conditions such as leprosy, only having seen it in white skin, on the other, with increasingly mixed communities in developed countries, range of diagnostic expertise required is greatly increased. The book opens with a short text highlighting particular difficulties in recognising skin disease in pigmented skin, mechanisms of pigmentation and heightened pigmentation after imflammation. Chapters are organised in a fairly traditional manner, obviously more according to the biological basis of the problem than similarity of appearance of two different problems in white skin, which would be irrelevant. Tropical and venereological issues are divided microbiologically, and AIDS is included with viruses
