Equine Juvenile Mandibular Ossifying Fibroma

Veterinary Pathology, 1988
Benign proliferative fibro-osseous lesions of the rostral mandible in six young horses are classified as equine juvenile mandibular ossifying fibroma. Histologically there is a characteristic abrupt transition from subgingival fibroblastic stroma to a zone of proliferating osteoblasts that form irregular spicules of osteoid.

Psammomatoid (Juvenile) Ossifying Fibroma of the Orbit

Ophthalmology, 1985
The clinical and pathologic features in 21 cases of a distinctive solitary fibro-osseous lesion affecting the orbit distinguished histologically by the dominance of numerous small round "psammoma-like" ossicles embedded in a cellular benign spindle cell stroma were studied.

Juvenile ossifying fibroma. An ultrastructural study

Cancer, 1978
The ultrastructural features of a juvenile ossifying fibroma of the maxilla are described. The stromal portion of the tumor was composed of osteoblasts and to a lesser extent of fibroblasts. The bone spicules were rimmed by osteoblasts and osteoclasts.

Psammomatoid Juvenile Cemento-Ossifying Fibroma of the Maxilla

Journal of Craniofacial Surgery, 2009
Both the trabecular and the psammomatoid juvenile cemento-ossifying fibromas (COFs) are specific entities among the COFs being distinguished because of their age predilection, site involvement, and clinical behavior. A case of a large-size juvenile COF of histologic psammomatoid pattern is shown.

Juvenile Active Ossifying Fibroma. Report of Four Cases

Journal of Neuro-Ophthalmology, 1997
✓ Juvenile active ossifying fibroma is a rare lesion seldom seen by neurosurgeons. It originates in the paranasal sinuses during childhood, grows slowly, and encroaches on adjacent orbital and cranial compartments. In the past 3 years, four patients with this lesion were seen (three men and one woman; mean age 28 years). The clinical presentations were

Juvenile trabecular ossifying fibroma: an update

Virchows Archiv, 2012
Fibro-osseous lesions are characterized by the presence of bone marrow that has changed into fibrous tissue and that contains mineralized material of varying appearances. Because of overlapping clinical, radiological, and histopathological features, their classification has evoked much discussion. The current classification recognizes fibrous dysplasia,

Juvenile Trabecular Ossifying Fibroma of the Orbit

Ophthalmic Plastic & Reconstructive Surgery
An 11-year-old male presented to the hospital with severe headache, nausea, and proptosis of the OD. Imaging revealed a 4 × 3 × 1 cm mass originating in the right orbital roof with adjacent bony remodeling, a calcific rim along the inferior extent of the lesion, and a heterogenous central component with hyper- and hypo-dense components.

Juvenile Psammomatoid Ossifying Fibroma

Clinical Nuclear Medicine, 2016
Juvenile psammomatoid ossifying fibroma is a rare bone-forming tumor seen in craniofacial bones, which affects mainly young patients. We report scintigraphic and SPECT/CT findings of 2 patients diagnosed with this disease. One patient presented with suspicion of fibrous dysplasia and the other with suspected malignancy in the setting of a rapidly ...
