Diagnosis and Management of Malignant Epithelial Nail Unit Tumors.

Abstract

Background: Malignant epithelial nail unit tumors pose significant diagnostic and therapeutic challenges due to their clinical presentation often mimicking benign conditions and due to the need to preserve as much nail unit function as possible during surgery. Early detection is crucial, even if none of these tumors represent a life-threatening disease. Objectives: This review focus on squamous cell carcinoma, verrucous carcinoma, eccrine porocarcinoma, onychocytic carcinoma, basal cell carcinoma, malignant onychopapilloma, malignant onycholemmal cyst and onycholemmal carcinoma. Methods: Existing literature on the aforementioned tumors has been revised and synthesized. Results: Clinical presentation, pathology, diagnostic procedures, risk factors and the challenges associated with surgical management have been described in detail. Conclusions: Malignant epithelial tumors of the nail unit require careful evaluation and management due to their complex presentation. Early detection and an informed surgical approach are essential to improve patient outcomes and minimize complications.
