    Other names: Sandpaper nails, twenty-nail dystrophy[1]
    SpecialtyDermatology
    SymptomsRough feeling nails with longitudinal ridges[2]

    Trachyonychia, also known as sandpaper nails, are characterized by rough feeling finger or toenails with longitudinal ridges.[2] Less frequently, it may be shiny with pits.[1] When the condition occurs on all the twenty nails of the fingers and toes, it is known as twenty-nail dystrophy, most evident in childhood.[3][4]

    It may occur in alopecia areata, atopic dermatitis, and lichen planus.[5][6]

    Signs and symptoms[edit | edit source]

    Trachyonychia causes the nails to become opalescent, thin, dull, fragile, and finely longitudinally ridged, and, as a result, distally notched.[7]

    Causes[edit | edit source]

    It can be a manifestation of lichen planus, psoriasis, alopecia areata, immunoglobulin A deficiency, atopic dermatitis, and ichthyosis vulgaris.[8]

    "The longitudinal striations can occur as a normal part of the aging process",[4] and not until the nails start to thin and get a sandpaper look is the condition called trachonychia. The nails are opalescent and frequently are brittle and split at the free margin. There has been evidence of the condition as a cutaneous manifestation of lichen planus. It has also been associated with other diseases such as eczema, psoriasis, alopecia areata, and atopic dermatitis.[4] Trachonychia is often seen in vitiligo patients – suggesting that they are more susceptible to this condition.[4]
