Amputation neuroma (NA) represents a reactive proliferation of neural tissue in an attempt to repair a nervous bundle traumatized by an accident or during surgical maneuvers. We report the case of a 65-year-old Black female patient with an injury that arose after a car accident 20 years ago. The patient attended the stomatology service reporting a “puff on the lip.” Upon intraoral examination, 2 nodular lesions in the region of the lower lip mucosa were noted, measuring 0.3 × 0.3 × 0.3 cm and 0.5 × 0.5 × 0.5 cm, with normal sharp limits, normal, fixed consistency, smooth and painless surface. The clinical hypothesis was hyperplasia caused by trauma. Excisional biopsy was performed and histopathologic sections revealed stratified keratinized squamous epithelium and the lamina propria, presenting a discrete chronic inflammatory infiltrate with hyperplastic vessels and neural bundles, confirming NA. This case reinforces the importance of the stomatologist in elucidating the diagnosis of lesions in the oral cavity caused by accidents.
