Description

Acquired unilateral macular melanosis, appearing late in the first decade of life, followed by the growth of coarse, long, dark hair at puberty. The pigmented spots are hand-sized. It is a common condition affecting all races and both sexes, but prevalent in young men. It may become evident or conspicuous on exposure to sunlight. In about 25 percent of cases it is caused by overexposure to sunlight.
