The traumatic neuroma (TN) is not a true neoplasm, but a reactive proliferation of neural tissue after transection or other damage to nerve bundles. A 32-year-old nonwhite male patient presented with a painful lesion in the buccal mucosa, which was first noticed 40 days before. Clinical examination revealed a small, soft, well-delimited, and purplish lesion, features that led to the clinical diagnosis of a vascular lesion. Based on that, it was decided on surgical removal of the lesion using a high-power diode laser (808 nm; 2.0 W; continuous mode). Microscopic examination revealed a random proliferation of mature, myelinated, and nonmyelinated nerve bundles within a fibrous stroma composed of connective tissue, which ranged from dense collagenized to myxomatous. Thus, the final diagnosis of TN was established. The patient had very good healing of the incised area on the postsurgical examination and underwent long-term follow-up with no lesion relapse within 12 months.
