Juvenile ossifying fibroma of jaws: a clinicopathological analysis of eight cases

Background Juvenile ossifying fibroma is defined as an aggressive variant of the ossifying fibroma and includes juvenile trabecular ossifying fibroma and juvenile psammomatoid ossifying fibroma. Materials and methods A retrospective review was made of all the biopsies performed at the Government Dental College, Trivandrum between 2001 and 2010. The reason for consultation was analysed, along with patient age, sex, clinical and radiological characteristics, tentative diagnosis, histological diagnosis, and treatment provided. Results and conclusion Among the eight cases reported as juvenile ossifying fibroma, there were five girls and three boys with a mean patient age of 14 years (range 9–20 years). The most frequent location was the mandible (six cases). Size of the lesions was 2 cm on average. Four patients presented with painful, hard tumour mass with a duration of several months. The remaining four cases were hard swellings without any symptoms. Four of the lesions were also completely radiolucent, three cases showed mixed radiolucent radio-opaque picture, and one was radio-opaque. Microscopically, four cases were trabecular variant, two were psammomatoid type, and rest of the two cases exhibited both patterns with a predominant trabecular pattern. Surgical resection was performed in all the eight cases. Follow-up was performed in six cases, of which two recurred after 3 years. Rest of the two patients did not report back to our institution.
