Schamberg,1 in 1901, was the first to describe this peculiar pigmentary disease. He described it at that time in the British Journal of Dermatology, and subsequently there have been seven other cases reported in the British dermatological journal. Kingery, so far as I can ascertain, was the first to report this condition in American literature. It is my opinion that the condition is not especially common in this country, and for this reason, another case may be of enough interest to be presented, with a brief review of the literature. It is interesting to note that all patients have been males; the condition is confined to the extremities; most of the cases have been reported in England; none have been reported on the Continent.
Schamberg's original patient was a boy, aged 15 years.
Upon examination, on each leg was a patch extending three or four inches below the knees
