ABSTRACT
Onychomatricoma (OM) is a fibroepithelial tumor of nail matrix that occurs in the digits of both the hands and feet. This was first reported by Baran and Kint. They initially described 3 cases, all of which demonstrated a filamentous tumor of matrix tissue that resulted in a thickened funnel-shaped nail. Although apparently benign, it is subject to recurrence, and long-term follow-up is recommended because it is not known whether there is a conversion to malignancy. Even though this neoplasm was first described more than 18 years ago, there remains a dearth of case reports (currently fewer than 50) in the literature. This is a single case report and literature review. Levels of Evidence : Therapeutic, Level IV.
