Approaches to Tumors of the Nail Unit and Genitalia.

ABSTRACT

The nail unit and genitalia represent rare locations where malignant tumors may arise. Human papillomavirus has emerged as a causative agent of the development of the most common malignancies in these sites. Tissue preservation with surgery is of utmost importance, and tissue-sparing approaches are increasingly emphasized in the dermatology, urology, and gynecology literature. In addition to its tissue-sparing nature, Mohs micrographic surgery allows the complete evaluation of histologic margins to ensure tumor extirpation and may be the ideal treatment modality. The authors herein present approaches for the evaluation and treatment of malignant tumors of the nail unit and genitalia.
