# Isolated Congenital Hyponychia and Anonychia in a Neonate: A Rare Case

## TL;DR

A full-term baby was born with rare nail abnormalities, including partial and complete absence of fingernails and toenails, with no other health issues.

## Contribution

This case report highlights the rare occurrence of isolated congenital hyponychia and anonychia in a neonate without associated syndromes.

## Key findings

- The neonate exhibited both hyponychia and anonychia affecting all fingernails and toenails.
- No systemic abnormalities or syndromic features were identified in the baby.
- The condition is likely isolated and carries a good prognosis when no other features are present.

## Abstract

Congenital hyponychia and anonychia are extremely rare nail disorders characterized by the partial or complete absence of nails. These conditions may be inherited or associated with in utero exposure to teratogenic substances. A full-term male neonate underwent routine head-to-toe examination in the labor room. The baby was noted to have both incomplete (hyponychia) and complete (anonychia) absence of fingernails and toenails. No other systemic abnormalities were identified. Isolated congenital hyponychia and anonychia are uncommon findings in neonates. In the absence of syndromic features, the condition generally carries an excellent prognosis.
