Adolescent with physiologic striae atrophicae of the thighs.

Physiologic striae atrophicae of adolescence occur mainly in healthy nonobese adolescents in association with the adolescent growth spurt. The striae typically present as erythematous, purple, or violaceous, horizontal linear plaques in the lumbar area. Occurrence of striae elsewhere on the body exclusively is rare. A PubMed search of the English literature using the key terms "physiological striae atrophicae of adolescence" OR "physiological striae atrophicae of puberty" AND "thigh" did not yield any prior report. We report a teenager with physiologic striae atrophicae of adolescence with striae restricted to the thighs.
