[Onychopapilloma : Diagnosis and surgical treatment of a rare nail tumor].

We report on two cases of nail tumors associated with onychorrhexis, distal V‑shaped onycholysis, and subungual keratosis. Surgical exposure was performed in each case to confirm the diagnosis. Histopathological examination revealed skin changes consistent with onychopapilloma. We describe two common surgical techniques in the treatment of onychopapilloma: classical longitudinal excision and alternative tangential excision with corresponding follow-up.
