Onychomadesis

Onychomadesis is a periodic idiopathic shedding of the nails beginning at its proximal end, possibly caused by the temporary arrest of the function of the nail matrix.[1]:784[2]:660

One cause in children is hand foot and mouth disease.[3] This generally resolves without complication.

Onchyomadesis can also occur if the nail is damaged or suffers a loss of blood supply, i.e. due to a bruise. The nailbed turns black, and the nail drops off shortly afterwards. It takes around 6 to 12 months to regrow.
