Non-Ossifying Fibroma in Posterior Mandible, A Case Report

In this case report, we present a case of non-ossifying fibroma in the mandible of an eleven-year-old girl who reported to the Oral and Maxillo-Facial Surgery Department with facial asymmetry and painless swelling on palpation over the lower right mandibular region. In this paper, we review the radiographic features, clinical presentation, and histopathological features of non-ossifying fibromas. Non-ossifying fibromas present with a unique extra-gnathic appearance in the skull. It is usually asymptomatic and has diverse histological features. Co-related histological, radiological, and clinical features differentiate it from other odontogenic and non-odontogenic tumors and cysts of the oral cavity. Ortho-pantogram revealed a well-demarcated, expansile radiolucency with pronounced sclerotic borders with striations reaching the anterior and superior regions and thus slowly approaching a multilocular stage. The treatment plan comprised of excisional resection with curettage under general anesthesia. After excisional biopsy of the lesion, the specimen was sent for histopathological evaluation in neutrally buffered 10 % formalin solution, which confirmed it to be a Non-Ossifying Fibroma. Prior to surgery, informed consent and written permission to collaborate with a case report encompassing her findings were obtained from the patients’ guardians. Confidentiality of patient has been taken care of before documenting the report. A meticulous literature review of previous case reports on non-ossifying fibromas revealed typical behaviors and characteristics of this lesion.
