What is onychopapilloma?
Onychopapilloma is a benign neoplasm of the nail matrix. It is usually an isolated lesion affecting one nail. Multiple nail involvement is rare and may be a sign of a BAP1 tumour predisposition syndrome. Rarely malignant onychopapilloma may occur with a histology of Bowen’s disease.
