Abstract

Central odontogenic fibroma is a very rare benign odontogenic tumour characterized by a fibrous mature stroma with variable strands or islands of inactive-looking odontogenic epithelium. Our aim is to report a case of a central odontogenic fibroma and describe the clinical usefulness of Er:YAG laser for the surgical treatment of this tumour. A 74-year-old woman presented with an expansive lesion located in a mandible with multilocular and mixed radiographic appearance. A conservative excision using Er:YAG laser was performed. Complete removal was obtained. There were no postoperative complications. The histopatologic features were consistent with the diagnosis of central odontogenic fibroma of rich-epithelium type. No recurrence was observed during follow-up.

Highlights

Central odontogenic fibroma (COF) is a very rare benign neoplasm characterized by a fibrous mature stroma with variable strands or islands of inactive-looking odontogenic epithelium [1]
Initial descriptions were somewhat confusing, with many central fibrous lesions such as hyperplastic dental follicle, desmoplastic fibroma, or myxofibroma classified as an odontogenic fibroma [5, 18]
Scattered remnants of inactive-looking odontogenic epithelium appear as small irregular islands and cords

Summary

Introduction

Central odontogenic fibroma (COF) is a very rare benign neoplasm characterized by a fibrous mature stroma with variable strands or islands of inactive-looking odontogenic epithelium [1]. COF accounts for less than 0.1% of oral lesions and 1.5% of all odontogenic tumours [2, 3]. They appear in a wide age group (4–80 years old) with predilection for females [4]. In the maxilla the tumour appears to frequently involve the anterior region, whereas in the mandible it involves more frequently the posterior region, with most lesions located in the premolar or molar area [7,8,9]. We report a case of a central odontogenic fibroma of the mandible with partially ill-defined margin treated with conservative excision using Er:YAG laser. The clinical, imaging, surgical, and pathological findings are discussed altogether with a brief review of the literature
