Congenital Onychodysplasia of the Index Fingers

Congenital Onychodysplasia of the Index Fingers Abstract To the Editor.— Attention has been given to congenital onychodysplasia of the index fingers (COIF)1 in Japan, with 16 case presentations in 1974. The polyonychia type of COIF was confirmed in a boy living in London, reported as having additional nails by Samman.2 With the exception of Maeda's two cases3 appearing in siblings, all cases have been reported to be nonfamilial. We observed a 2-day-old girl with the micronychia type of COIF. Report of a Case.— A Japanese girl, born at full term on Feb 5, 1975 at the National Kumamoto Hospital, was examined by us two days later. Her 25-year-old mother had blood type 0, Rh negative, and her 23-year-old father and 2-year-old sister had blood type B, Rh positive. Neither of them had any other abnormalities, including nail changes. The patient's blood type was B, Rh positive, but there was no substantial rise in her References 1.
