ABSTRACT
The male genitals are normally more pigmented than other areas of skin. This is particularly noticeable in the pigmentation of the scrotum. Genital pigmentation may be isolated or may be a part of a widespread pigmentation disorder. Systemic disorders such as Addison's disease will give hyperpigmentation over various parts of the body, not just the genitals. A lentigo (plural lentigines) is a melanocytic lesion of the skin clinically similar to a freckle. Lentigines on the genitals and mucosal surfaces may indicate a genetic disorder. Vitiligo is a common skin condition resulting in destruction of melanocytes. It occurs in all races at a rate of 1–2%. It commonly presents between 10 and 30 years of age. Diagnosis is made clinically but may be facilitated by the use of the Wood's light in order to visualise areas of pigment loss. Treatment options on the genitals are limited. There are some normal variants that may present as a pigmentary problem.
