Abstrakt: Background: The group of fibro-osseous lesions from the maxillofacial region is very heterogeneous, but what they all have in common is the substitution of normal bone by fibroblasts with the consequent formation of collagen fibers, as well as substitution by different types of mineralized tissues which may be similar to bone or cement. Within this group of lesions, the juvenile ossifying fibroma is found, considered a rare and recurrent benign fibro-osseous neoplasia. The term juvenile ossifying fibroma has been used in the literature to describe two histopathological variations of conventional ossifying fibroma. These variations are trabecular juvenile ossifying fibroma and psammomatoid juvenile ossifying fibroma. Psammomatoid juvenile ossifying fibroma is an uncommon bone-forming neoplasm with aggressive local growth. Diagnostic of this lesion occurs after the correlation of clinical, imaging, and histopathological findings. Proposed treatments range from enucleation and curettage to resection of the tumor.
Objectives: The present article has as its objectives to report an uncommon case of a 4-year-old male patient treated by conservative approach and revise the literature on juvenile ossifying fibroma.
Conclusions: Psammomatoid juvenile ossifying fibroma, for its being very uncommon, warrants further investigation in order to establish the best treatment, principally in children, with a view to minimizing mutilating treatments. In the case examined, a conservative treatment was chosen, where the surgeon established curette and cryotherapy, and the reintegration of the child in his social environment, without relapse during the first year of therapy.
