A 9 1/2-year-old girl was seen with 20-nail dystrophy. Lichen planus was suspected and further examination revealed other lesions localized to the oral mucosa. The diagnosis was confirmed as lichen planus by biopsy of tissue from the oral lesions. Careful examination of all mucocutaneous surfaces is recommended before accepting the diagnosis of so-called isolated 20-nail dystrophy of childhood.
一名9岁半的女孩被发现患有20甲营养不良。怀疑是扁平苔藓，进一步检查发现其他病变局限于口腔黏膜。通过对口腔病变组织进行活检，确诊为扁平苔藓。在接受所谓儿童孤立性20甲营养不良的诊断之前，建议仔细检查所有黏膜皮肤表面。
