title: A case of double fingernail and ectopic fingernail.
abstract: Congenital ectopic fingernails are extremely rare and only 22 cases were found in domestic and foreign literature during our investigation. In the 22 ectopic fingernail cases collected, small ectopic fingernails were found along side the normal fingernail (dorsal or palm side), in most cases, and extremely rare double nails, which are as large as normal nails, were found on the palm side opposite the normal fingernail in some cases. We encountered a 4-year-old boy with a double fingernail on the right fifth finger and an ectopic fingernail on the left fifth finger. The nail on the palm side, including the fingernail block and nail matrix, was excised from the right fifth finger and the defect was reconstructed with a palm skin flap.
