Congenital onychodysplasia of the index fingers (Iso and Kikuchi syndrome) is characterized by five criteria: (1) congenital occurrence, (2) unilateral or bilateral index finger involvement, (3) variability in nail appearance, (4) possible hereditary involvement, and (5) frequently associated bone anomalies. Emphasis is placed on the configuration of the lunula, which is deformed and plays an important role in shaping the free edge of the nail plate. To our knowledge, this deformity has not been previously described in this syndrome.
先天性食指甲发育异常（矶部和菊池综合征）具有五个特征：（1）先天性发病；（2）单侧或双侧食指受累；（3）指甲外观多变；（4）可能存在遗传因素；（5）常伴有骨骼异常。重点关注甲半月的形态，其发生变形并在塑造甲板游离缘方面起重要作用。据我们所知，这种畸形在此综合征中此前尚未有过描述。
