Congenital Onychodysplasia of Index Fingers: Iso-Kikuchi Syndrome

A 4-year-old girl presented for evaluation of partial nail growth of the bilateral index fingers. There was no history of trauma, complications during pregnancy, family history of similar eruption, or any other inciting event. Further history revealed that this nail dystrophy was present at birth and it had been unchanged. Examination showed that the nail plate was present only in the ulnar one-third of the index fingers bilaterally (Figure, A; white arrows). There was complete absence of the nail plate, matrix, and apparatus on the radial two-thirds of the affected fingernails (Figure, A; black arrowheads).
