Anonychia refers to a complete reversible or irreversible nail loss occurring on one, several or all fingers or toes. Acquired (non-genetic) nail loss is usually acquired as a result of serious (dermatological) disease or trauma (see below: Anoynchiea) of one or more nails on fingers and/or toes. Anonychia is observed in the following diseases and events:
