Rare localization of a traumatic neuroma of the hard palate: A case report

Abstract

Traumatic neuroma is an exuberant and disorganized but non-neoplastic process of regeneration of the proximal stump of a peripheral nerve. Its occurrence in the oral cavity is rare and usually involves the mandible or tongue, almost always associated with a traumatic event such as surgery, tooth extraction or an inflammatory process.

It is characterized by the presence of pain, burning, or paresthesia and rarely involves hard palate. We present the case of a 35-year-old female patient with, approximately five years prior, a new growth in the left hard palate region. The patient did not report any significant medical history, nor any traumatic or inflammatory events involving the oral cavity. She provided facial CT images, which were negative for pathologies. A biopsy of the new growth was performed, and the histological report confirmed the diagnosis of "traumatic neuroma". The traumatic neuroma was completely excised preserving the adjacent bony structures. After complete removal of the lesion the symptoms disappeared.
