Onycholemmal Carcinoma: A Rare Nailbed Tumor Managed With a Digit-Sparing Approach.

Abstract

Onycholemmal carcinoma is a rare subtype of squamous cell carcinoma deriving origin from the nailbed epithelium. With only 16 available reports in the literature, there is no standardized diagnostic or management algorithm. Treatment is largely center-specific, with most cases involving distal amputation of the affected digit. The purpose of this case report is to highlight challenges in diagnosis and advocate for a digit-sparing approach.
