Trachyonychia (rough nails)

“…They described seven cases: four were in one family, two in another and one independent; all but one was a child. Uniform pitting of nails has for a long time been known to be caused by psoriasis (Klingmuller & Reh, 1955) and by alopecia areata (Stuhmer, 1957). Uniform pitting will roughen the nail surface but does not produce as great a deformity as in the cases I am describing.…”
