摘　　要：BACKGROUND Lichen planus(LP)with distribution of lesions along Blaschko’s lines is a rare entity,accounting for 0.24%-0.62%of all patients.Unilateral distribution of lesions in arm,leg,trunk,and waist is even less common.Approximately 10%of patients with LP manifest nail lesions.CASE SUMMARY A 20-year-old woman presented to our department with polygonal,purpuric,flattopped papules over the right arm,right leg,and right side of trunk and waist for the last 5 mo.The patient initially developed nail deformation in the left middle finger with no obvious cause,followed by development of blue-purple and red maculopapular rash with pruritus.During the disease course,the skin lesions aggravated and spread to several segments due to scratching.The lesions showed unilateral distribution along the Blaschko’s lines.The diagnosis of LP along Blaschko’s lines was established based on dermoscopy and skin biopsy.Her cutaneous lesions considerably improved after 4-wk treatment with intramuscular glucocorticoid,oral acitretin,topical glucocorticoid,and retinoids.CONCLUSION Cases of LP involving multiple segments of the body along the Blaschko’s lines with nail damage are rare.
