Abstract

Onychomadesis describes complete nail shedding from the proximal portion. It is consecutive to a nail matrix arrest and can affect both fingernails and toenails. It is a rare disorder in children. Except for serious generalised diseases or inherited forms, most cases are considered to be idiopathic. Nail matrix arrest has been associated with a variety of drug exposures and systemic illnesses, including infections, and may result in a variety of changes, including transverse ridging (Beau's lines) and nail shedding (onychomadesis).
