【 摘 要 】

We recently treated a patient who presented with a hyperpigmented longitudinal stripe of the thumb nailbed which was biopsied with a histopathologic diagnosis of onychopapilloma. We have not seen onychopapilloma reported in the hand surgery literature. Onychopapilloma is generally benign but a malignant variant has recently been reported.
