Twenty-nail dystrophy (trachyonychia) caused by lichen planus in a patient with alopecia universalis and ichthyosis vulgaris.
A 7-year-old girl with alopecia universalis had dystrophy of all 20 nails. A nail biopsy specimen disclosed features of lichen planus. The patient also had ichthyosis vulgaris and hypogammaglobulinemia. We are not aware of any previous reports of these associations, which we believe to be noncoincidental.
