Abstract Peripheral Ossifying Fibroma (POF) is a reactive, non-neoplastic gingival growth commonly seen in anterior maxilla, typically affecting young females. This case report presents an unusal occurrence of Peripheral Ossifying Fibroma (POF) in mandibular anterior region of a 65 years old female patient. The patient reported with a painless, slow growing gingival mass between the mandibular lateral incisor and canine since 2-3 months. Clinical examination revealed a firm, well demarcated lesion with no associated bone involvement. Radiographic imaging shows no significant underlying osseous changes. Excisional biopsy was performed and histopathological analysis confirmed the diagnosis of Peripheral Ossifying Fibroma, characterised by a fibrous connective tissue matrix with calcification resembling bone and cementum. This case highlights the POF in differential diagnosis of gingival lesion in older patient and emphasizes the need for histopathological evaluation for appropriate diagnosis and management.
