Subgemmal neurogenous plaque of the tongue: a report of three cases

Amanda Katarinny Goes Gonzaga et al. Oral Maxillofac Surg. 2017 Sep.

Abstract

Subgemmal neurogenous plaque (SNP) is a biphasic neural structure associated with the taste buds. Clinically, SNP usually presents as an asymptomatic, normally colored, papule located in the posterior lateral border of the tongue. Accurate diagnosis is based only on histopathological examination, which shows a superficial neurofibroma-like pattern and a neuroma-like in the deep zone. Appropriate recognition of clinical and morphological aspects of SNPs can avoid their misdiagnosis as neural neoplasms. We report three cases of SNP with detailed clinical, histopathological, and immunohistochemical features.

Keywords: Neural structures; Schwann cells; Subgemmal nerve plexus; Tongue.
