A Case of Congenital Onychodysplasia of the Index Finger / 대한피부과학회지

ABSTRACT

Congenital onychodysplasia of the index fingers(COIF) is a rare condition of the nails, characterized by the following (1) congenital occurrence, (2) unilateral or bilateral index finger involvement, (3) variability in nail appearance such as anonychia, micronychia, and polyonychia, (4) possible hereditary involvement, and (5) frequently associated bone anomalies. A 7-week-old male baby with an atrial septal defect presented with micronychia of the left index finger. Roentgenogram of both hands revealed a bone defect of the left 2nd distal phalanx. To our knowledge, distal phalangeal bone defect has not been previously described in this disease. We report a case of COIF with atrial septal defect.
