en Clinical Medicine Clinical Medicine گزارش موردی Case Report Article <span style="font-size:10pt"><span new="" roman="" style="font-family:" times="">Lichen striatus (LS) is an uncommon dermatosis. Nail involvement in this disorder is rare.&nbsp; Diagnosis is usually based on characteristic clinical features include linear papules along Blaschko lines and partial dystrophy of a single nail. LS is self-resolving and gradually improves over several months to years. We report a 5-year- old girl with LS that presented with asymptomatic linear skin colored papules which had extended from left elbow to left index finger nail. Simultaneous lateral nail dystrophy was consistent with nail LS diagnosis. Currently there is no specific treatment for LS and its nail dystrophy. However, prescription of topical steroid and calcineurin inhibitors have been ordered. For the current case, we prescribed topical triamcinolone.</span></span><br> &nbsp; Lichen striatus , nail dystrophy , blaschko lines 163 167 http://journal.zums.ac.ir/browse.php?a_code=A-10-6896-1&slc_lang=en&sid=1 Ali Sayyadinejad asayyadinejad@gmail.com 5200319475328460080491 0009-0003-8903-4046 Yes Department of dermatology, Vali-e-Asr hospital, School of medicine, Zanjan university of medical Sciences, Zanjan, Iran Sahar Hoseinkhani hoseinkhani.s20@gmail.com 5200319475328460080492 0009-0006-3862-905x No Department of dermatology, Vali-e-Asr hospital, School of medicine, Zanjan university of medical Sciences, Zanjan, Iran
