A 12-year-old boy presented with asymptomatic linear skin lesions over the back. There was no history of exercise, trauma, excessive or rapid weight gain or loss, and topical or systemic drug use. Examination showed multiple transverse, slightly elevated, yellow streaks of varying lengths over back (Fig. 1). A diagnosis of linear focal elastosis (LFE) was made. Parents were counselled and no specific therapy was initiated.

LFE is a benign condition characterised by asymptomatic yellowish, palpable linear striae over middle and lower back. LFE classically occurs in older males and has rarely been reported in children less than 15 years. Exact pathogenesis is not known, though both degeneration and regeneration of elastic fibres is thought to contribute towards skin lesions. Differential diagnosis includes striae distensae which are white to pink coloured depressed skin lesions over abdomen, thigh and arms. Systemic associations have not been reported, and no treatment is usually required.
