Onychomadesis is the spontaneous, complete shedding of the nail from its proximal side, without pain or inflammation, following nail matrix arrest.

Brian Maurer, a pediatric practitioner, recently saw a 5-year-old boy with a two-week history of nail shedding.  The child had antecedent Hand, Foot and Mouth disease.  Nail shedding has been described as a sequela to HFM Disease.
