Twenty Nail Dystrophy in Two Siblings / 대한피부과학회지

ABSTRACT

Two siblings, a 42-year-old man and his 39-year-old sister, have had severe twenty nail dystrophy which began to develop in adulthood. The nails are variably involved and show thickening, ridging, koilonychia, opalescence, and loss of luster. There is no evidence of other skin disorders such as psoriasis, lichen planus, or alopecia areata. No other family members through three generations have had similar nail changes. Our cases are unique in that severe twenty nail dystrophy may concurrently affect two siblings during adulthood.
