Absence of fingernails and toenails

The absence of fingernails and toenails, known as anonychia, can be congenital or acquired. Congenital anonychia is a rare genetic condition where individuals are born without nails, while acquired forms can result from trauma, infections, or certain medical conditions like psoriasis or fungal infections. Lack of nails may lead to increased sensitivity in the fingertips and toes, and can also affect grip, dexterity, and protection for the distal phalanges. Treatment options depend on the underlying cause and may include protective measures or addressing the specific health issues involved.
