Cystic degeneration in cemento-ossifying fibroma: Diagnosis challenge and conservative management - Case report.

Abstract

Introduction and importanceCemento ossifying fibroma (COF) is an encapsulated lesion that is often found in the mandible of middle-aged females. Cystic degeneration may be associated to several osseous lesion. This particular presentation is not well documented in the jaws.Case presentationPatient presented was referred to oral surgery department for abnormal radiolucency in the right mandible on panoramic X-ray. The patient did not have any specific medical history and reported painful areas in right mandibular region. During diagnosis assessment, ameloblastoma was first considered due to the presence of cystic lesion clusters. But the mixed image in previous X-ray pointed to a fibro-osseous with a change in pathogenesis pathway. Diagnosis buildup was based on previous radiographs, incisional biopsy was proposed to identify the histopathological feature of the lesion before proceeding to further investigation (CBCT) or treatments (decompression or enucleation). COF of the jaws associated to non-specific cystic changes was the histopathological diagnosis. Delay in treatment showed an unexpected outcome with good clinical and bone healing.Clinical discussion and conclusionThis case shows the importance of previous radiographs, when available, in diagnosis buildup. The fibro-osseous lesion with cystic change may show a good biological response with conservative management. A clinical and radiological surveillance after a conservative treatment may be a better option in treatment of these lesions.
