PERIPHERAL ODONTOGENIC FIBROMA IN THE MANDIBULAR ANTERIOR REGION: A RARE CASE REPORT

Abstract

Background: Peripheral odontogenic fibroma (POdF) is a rare benign odontogenic neoplasm arising from the gingival soft tissues. It accounts for a very small proportion of odontogenic tumors and is frequently mistaken clinically for more common reactive gingival lesions such as pyogenic granuloma, peripheral ossifying fibroma, or irritation fibroma. Histopathological examination is therefore essential for definitive diagnosis. Case Presentation: A 67-year-old male presented with a painless, slowly enlarging pedunculated swelling in the mandibular anterior region that had been present for 10 years. The lesion measured approximately 3 × 2 cm and was fibrous without ulceration or bleeding. Clinical and radiographic evaluation revealed retained root stumps in relation to teeth 31, 41, and 42. Following an excisional biopsy, complete surgical excision of the lesion with extraction of the retained root stumps was performed. Histopathological examination confirmed the diagnosis of peripheral odontogenic fibroma. Healing was uneventful, and an interim removable partial denture was provided one month after surgery. Conclusion: Peripheral odontogenic fibroma should be considered in the differential diagnosis of long-standing gingival enlargements. Careful clinicopathological correlation and complete surgical excision are essential for accurate diagnosis, successful treatment, and prevention of recurrence.
