Synopsis

Lichen striatus is a benign skin eruption of childhood of uncertain etiology. Often, there is a sudden onset of unilateral, linearly arranged, asymptomatic papules. The eruption usually occurs on the extremities of children aged 5-10, but it may arise in infancy. The eruption evolves over a few days to a few weeks and resolves over 6 months to a year. Girls are affected 2-3 times as often as boys. Though infrequent in the genital area, lichen striatus can occur in this region.
