%X The aim of the present article is to present the clinical case of a large peripheral ossifying fibroma that evolved from a previously diagnosed pyogenic granuloma in a 50-year-old woman. The patient was referred for treatment of a lesion over the buccal and palatal gingiva close to the left upper first molar. It was purplish-red in color, approximately 3 cm in diameter, having a smooth surface, a pedicled and bleeding base, with seven years of evolution, and diagnosed as pyogenic granuloma. After three years of evasion, the patient returned reporting an increase in the lesion and difficulty in eating. Clinically the nodule was lobular in appearance, pink in color and smooth, pediculated, firm in consistency, non-bleeding, about 5 cm in its greatest extension, extending to the maxillary tuberosity. The lesion was excised and referred for histopathological examination, which led to the diagnosis of peripheral ossifying fibroma. The patient was followed for approximately 18 months, prosthetically rehabilitated, with satisfactory healing and no clinical signs of recurrence. The possible evolution of a pyogenic granuloma to a peripheral ossifying fibroma was observed in this case, based on the histopathological changes that occurred, with the development of calcified material, fibrous maturation, and decreased vascular content of the initial lesion after three years.
