Demographic characteristics of teenage boys with horizontal striae distensae of the lower back.

Our results indicate that horizontal striae distensae of the lower back in adolescent boys is associated with a rapid growth spurt, tall stature, and family history of striae distensae. There is no association between this type of striae distensae and any chronic medical condition, bacterial infection, or exogenous steroid use. Thus a careful review of systems and counseling without further medical testing is reasonable management.
