Traumatic neuroma in the lower lip arising following laser/cryosurgery to treat a mucocele

Abstract

A 15-year-old girl presented with a painless recurrent swelling on her right lower lip mucosa for about 10 months. She had a past history of treatment with laser surgery and cryosurgery. The clinical diagnosis was a 'recurrent mucocele'. Histopathological examination of the surgical specimen revealed a mucocele close to a neuroma with irregular nerve fascicles, leading to a diagnosis 'mucocele accompanied with a traumatic neuroma'. In the present report, the traumatic neuroma appears to have arisen following laser or cryosurgery.
