It occurs as a common manifestation of various dermatoses affecting the nail unit like lichen planus, psoriasis, atopic dermatitis, onychomycosis, vitiligo and alopecia areata, but isolated cases without an associated disease are rare. TND is a manifestation of diverse underlying processes; therefore its histology will vary; however, histologic data on TND are only available in very few published reports. We are documenting the histologic features of TND in a 12-year-old boy who presented with thin rough opaque lusterless nail plates with longitudinal ridging of the twenty nails without any systemic involvement.}, keywords = {Lichen Planus,twenty nail dystrophy,trachyonychia}, url = {https://www.iranjd.ir/article_98156.html}, eprint = {https://www.iranjd.ir/article_98156_eeb52f2ba775dc95ab27773f284e50be.pdf} }
