Woman loses toenails after fish pedicure

Dermatologists say the practice is fraught with risk

An unconventional foot spa treatment using fish has left a young woman with significant toenail abnormalities and shedding of the nail plate, according to the doctor reporting her case in JAMA Dermatology.

According to the case report, the woman had a six-month history of abnormal toenails. 

She denied pain, previous trauma or running or walking on paved road.

She had no family history of nail disorders, no medical problems, no history of major illness or high fever and no vaccinations or use of medications in the past year. 

But some months before the start of her nail abnormalities, which were later diagnosed as onychomadesis, she reported having a fish pedicure.
