Psammomatoid juvenile ossifying fibroma of mandible in a 6-year-old child.

Manjunatha BS, Purohit S, Kiran S, Mahita VN - Indian J Dent (2016 Jan-Mar)

Bottom Line: The psammomatous type of JOF (PsJOF) principally involves the bones of the orbit and paranasal sinuses.Here, we report a challenging case of PsJOF in a 6-year-old child with a complaint of swelling imitating a cystic lesion in left back region of the lower jaw for 2 months.The authors propose that a careful examination and correlations of clinical, radiological, and histopathological features are essential to arrive at correct diagnosis and play a vital role in management of such patients.

ABSTRACT
Juvenile ossifying fibroma (JOF) is a rare fibro-osseous lesion of the jaw occurs at the early age of onset frequently under 15 years with a propensity to recur. It appears as a unilobulated/multilobulated lesion at an early stage followed by radiopaque appearance surrounded by radiolucent rimming at advanced stages. The psammomatous type of JOF (PsJOF) principally involves the bones of the orbit and paranasal sinuses. However in some cases, maxilla or rarely the mandible may be pretentious. Here, we report a challenging case of PsJOF in a 6-year-old child with a complaint of swelling imitating a cystic lesion in left back region of the lower jaw for 2 months. The authors propose that a careful examination and correlations of clinical, radiological, and histopathological features are essential to arrive at correct diagnosis and play a vital role in management of such patients.

Figure 6: Photomicrograph showing spherical structures having basophilic in the center and eosinophilic in periphery

Mentions: Aspiration cytology was accomplished to rule out any arteriovenous malformations, cystic lesions, and the fibro-osseous lesions. Based on the clinical and radiographic features, a diagnosis of “OF” was made. Aspiration of the lesion exhibited only blood with few surface squamous cells. The lesion was removed by surgical enucleation under local anesthesia. The surgical specimen had multiple tissue fragments [Figure 3]. The histopathological examination showed a fibrocellular connective tissue composed numerous bundles of collagen fibers with proliferating round to stellate fibroblasts. Numerous eosinophilic spherical structures dispersed in the fibrous stroma [Figures 4 and 5] were noted. Spherical structures were basophilic in center and eosinophilic in periphery [Figure 6] termed as psammoma bodies. Histopathology report was suggestive of “psammomatoid type of juvenile OF (PsJOF).” Regular follow-up after 3 months with no evidence of recurrence and lost for follow-up later on.
