Here, we present a case report of peripheral ossifying fibroma (POF) in an adult lady in her fourth decade of life. This case report comprises the growth that occurred in the mandibular anterior region with displacement of anterior teeth, its satisfactory management and literature review. POF represents a reactive benign lesion of connective tissue and is not the soft tissue counterpart of ossifying fibroma and is also not related anyhow to peripheral odontogenic fibroma. POF in the age of 45 years, arising in the mandibular anterior region, is an occasional entity. Careful clinical examination and histopathology findings should be correlated to conclude the final diagnosis.
