Pediatric Traumatic Neuroma of the Upper Lip - A Case Report

Abstract

Traumatic neuroma (TN), represents a reactive proliferation of neural tissue following damage to an adjacent nerve. Clinically, patients usually present with inimitable pain, oral lesions appearing as nodule of size less than 2 cm with normal or greyish white smooth surface mostly involving the mental foramen, tongue or the lower lip. We report a rare case of an upper lip traumatic neuroma, in an uncommon age group and uncommon location, which was clinically thought to be hemangioma. Histopathologically, excision biopsy specimen showed haphazard proliferation of fascicles of nerve fibres. Immunohistochemical analysis revealed strong cytoplasmic positivity for S100 and was negative for SMA and CD34, affirming the neural origin of the lesion. TN could be considered as a differential in cases of soft tissue swelling from uncommon location in the oral region especially in the pediatric age group, where a clear trauma history cannot always be illustrated.
