Depigmentation of the male genitalia

A study of the incidence of depigmentation of the male genitalia in patients attending a dermatology clinic is presented. Of the 5,000 consecutive new male patients examined, thirty-eight patients had white patches on the genitalia, sixteen of which were leukoderma due to post inflammatory hypopigmentation. The remaining twenty-two were classified as vitiligo, with no known cause.
