Amputation neuroma with foreign body reaction by suture thread in the region of mental foramen-Report of a case

Abstract

Amputation neuroma in the oral region is rarely seen after surgical procedure, especially tooth extraction, and trauma. This is defined pathologically as non-neoplasma showing nodular hyperplasia of nerve fibers.
A case of this is presented in this report. A 49-year-old woman visited our clinic with a chief complaint of painful nodule formation. Onset of this pain was two years ago after frenotomy of right lower buccal frenulum.
The nodule exising under normal mucosa was red-bean size at first consultation. Pressure on this area aggravated the pain. It was, therefore, suspected clinically as a kind of amputation neuroma. Surgery was performed under local anesthesia.
The nodule combined with mental nerve and was excised easily. Microscopically, the nodule composed of foreign body reaction to suture thread at superficial portion and amputation neuroma in the deeper one. Severe pain disappeared postoperatively.
