Background: Traumatic neuroma is an uncommon, reactive, non-neoplastic proliferation of nerve tissue that develops following nerve injury or transection. It typically presents as a small, nodular lesion in areas prone to trauma, such as the lower lip, tongue, or mental foramen region. Clinically, it may appear as a painless or occasionally tender swelling and is often associated with a history of local trauma or chronic trauma. Case presentation: A 25-year-old Sudanese male presented to the Oral and Maxillofacial Surgery clinic with a localised swelling in the lower lip for approximately one week. The patient reported a history of repeated lip biting prior to the onset of the lesion. The swelling was initially small and gradually increased in size. It was painless, with no associated bleeding or discharge. Radiographic examination revealed no abnormality. An excisional biopsy was performed under local anaesthesia, and the specimen was submitted for histopathological evaluation, which confirmed the diagnosis of traumatic neuroma. Conclusion: This case highlights the importance of considering traumatic neuroma in the differential diagnosis of oral soft tissue lesions, particularly in the presence of a history of trauma. Histopathological examination remains the gold standard for definitive diagnosis, and surgical excision is associated with an excellent prognosis.
