Longitudinal Nail Biopsy: Utility in 20-Nail Dystrophy

Abstract

These data reveal the clinical profile and common associations of TND. They also confirm the diagnostic utility of nail biopsy in TND patients and advocate this procedure in cases in which the clinical diagnosis is otherwise obscure. However, it cannot be recommended in the routine evaluation of patients with a relatively benign disorder such as TND. Furthermore, nail biopsy is proven to be a relatively simple and useful procedure.
