[Isolated neurofibroma of oral cavity. An unusual manifestation case report .].

Introduction: Neurofibroma (NF) is a benign tumor originated from neuronal cells, and can occur alone or multiple. Its manifestation within the oral cavity is rare, with a wide age range of appearance. This tumor occurs in a sessile-based nodular form, with slow growth and variable size.

Objective: The purpose of this work is to present a clinical case of a solitary neurofibroma, of rare manifestation, in the oral mucosa.

Methodology: an 86-year-old male patient attends the dental office with a right side facial asymmetry, and without pain. At the time of patient inspection, a nodular lesion with a sessile base, mobile, approximately 5cm long and 3cm wide, is observed. The planned treatment consisted of the complete surgical removal of the tumor mass. The study of pathological anatomy reveals that it is a solitary neurofibroma.

Conclusion: In the case presented in this work, it was the correct surgical intervention and the antomopathological study of the operative piece, which made a definitive diagnosis of the lesion.
