fa عمومى General گزارش مورد case report Peripheral cemento-ossifying fibroma (PCOF) is a relatively rare tumor classified between fibro-osseous lesions. This lesion is more common in the maxilla than the mandibula. About 60% of the tumors occur in the maxilla and also more than 50% of all lesions affect the anterior region of the maxilla. The management of a pediatric patient with PCOF requires early diagnosis and treatment. Appropriate treatment protocol with close post-operative follow-up is required for these patients. We report here, the clinical case of a 9-year-old girl, with the disease duration of 1 year and was followed-up for 2 years post-surgically showing gingival health, normal radio-opacity of bone without any recurrence.
