Trachyonychia is a condition characterized by rough accentuated linear ridges (longitudinal striations) on the nails of the fingers and toes.[3] 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,[4] favoring males.[2][5]

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

immunoglobulin A deficiency, atopic dermatitis, and ichthyosis vulgaris.[7]

"The longitudinal striations can occur as a normal part of the aging process",

eczema, psoriasis, alopecia areata, and atopic dermatitis.[2] Trachonychia is often seen in vitiligo patients – suggesting that they are more susceptible to this condition.[2]
