Lichen striatus (LS) is a relatively rare and self-limited linear dermatosis of unknown etiology. It primarily affects children, with more than 50% of cases occurring in patients aged 5 to 15 years. The case of a 2-year-old boy who presented for evaluation of a nonpruritic linear rash on the left side of the lower abdomen of 3 weeks' duration is discussed. A diagnosis of lichen striatus (LS) was made and the lesions completely resolved within 6 months. At 5 years of age, the patient returned for evaluation of bluish discoloration and thinning of the nails on the left middle and ring fingers, which ultimately fell off and started to regrow 2 months prior to the second evaluation. The rare diagnosis of isolated onychodystrophy as a late manifestation of LS was made.
