Oral soft-tissue biopsy: an overview

Proper management of an oral mucosal lesion begins with diagnosis, and the gold standard for diagnosing disease, oral or otherwise, is tissue biopsy.

These challenges are further compounded by the myriad of biopsy techniques and devices now available. In addition, certain oral subsites are subject to diagnostic pitfalls that necessitate modifications of technique. This article provides an overview of the oral soft-tissue biopsy and highlights some potential pitfalls.
