Traumatic neuroma of mental nerve following lower lip mucocele excision

Abstract

Traumatic neuroma represents reactive hyperplasia of irregularly positioned Schwann neurofibril cells and connective tissue - stroma that develop as a result of unsuccessful attempts to regenerate peripheral nerve after injury. This paper presents the case of a patient with painless traumatic neuroma of the lower lip formed in the same place where he previously had surgically removed salivary cyst of minor salivary gland - mucocele. Histopathological examination confirmed the diagnosis of traumatic neuroma.

Traumatski neurom predstavlja reaktivnu hiperplaziju iregularno postavljenih Švanovih ćelija i neurofibrila u vezivno-tkivnoj stromi koja nastaje kao posledica neuspešnih pokušaja regeneracije nakon povrede perifernog nerva. U ovom radu je prikazan slučaj pacijenta sa bezbolnim traumatskim neuromom donje usne koji se pojavio na istom mestu gde je prethodno hirurški uklonjena salivarna cista male pljuvačne žlezde donje usne - mukokela. Histopatološki nalaz je pokazao da je uklonjena promena bila traumatski neurom.
