Peripheral cemento-ossifying fibroma (PCOF), a rare reactive gingival overgrowth occurs frequently in maxillary anterior region with a peak incidence between second and third decades of life. It is a slow growing spherical benign tumour with unknown aetiopathogenesis. Based on only clinical examination, diagnosis ofPCOF is difficult to make. Hence, histopathological examination becomes imperative for definite diagnosis and proper management. Long-term follow-up is extremely important because of high recurrence rate. Herewith, a case of PCOF is presented in a 31 years old female patient complaining of slow growing and asymptomatic gingival overgrowth at uncommon location.
