Juvenile psammomatoid ossifying fibroma of the calcaneus

BMJ Case Reports, 2020
Juvenile ossifying fibromas (JOFs) are a rare group of fibro-osseous lesions, typically of odontogenic origin. Juvenile psammomatoid ossifying fibroma (JPOF) is one variant, that is, histopathologically distinguished by spherical ossicles resembling psammoma bodies.

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 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 ...

Juvenile Psammomatoid Ossifying Fibroma (JPOF) of Maxilla—A Rare Entity [PDF]

Journal of Maxillofacial and Oral Surgery, 2011
Juvenile Ossifying Fibroma (JOF) is an uncommon fibro-osseous lesion affecting the facial bones. Although a benign entity, JOF is known to be locally aggressive and has a high tendency to recur. Two distinctive microscopic patterns have been described; a trabecular variant and a Psammomatoid variant.

Juvenile Psammomatoid Ossifying Fibroma in Paranasal Sinus and Skull Base

Acta Oto-Laryngologica, 2017
The endoscopic transnasal approach with IGS is a safe and effective technique, allowing completely resection of JPOF, with minimal morbidity and recurrence.JPOF is a benign but locally aggressive fibro-osseous lesion. This study presents a series of JPOF cases, involving anterior skull base and orbit, treated by endoscopic transnasal approach with ...

Ultrastructual morphology of juvenile psammomatoid ossifying fibroma

Auris Nasus Larynx, 2012
We investigated the ultrastructural morphology of the hard tissue in a fibro-osseous lesion. Bone samples were obtained from a juvenile psammomatoid ossifying fibroma and were observed under a scanning electron microscope. The lesion had a spongy lamellar structure containing bony tissue. On histological examination, resorbing preexisting lamellar bone

Juvenile psammomatoid ossifying fibroma of the neurocranium

Journal of Neurosurgery, 2005
✓ Juvenile psammomatoid ossifying fibroma (JPOF) is a benign fibroosseous lesion predominantly arising within the paranasal sinuses in children and young adults. Neurocranial occurrence is exceedingly rare and a location within the neurocranial portion of the temporal bone has not been described.

Juvenile Psammomatoid Cemeto-ossifying Fibroma of Mandible: a Diagnostic dilemma

BMJ Case Reports, 2021
Psammomatoid Juvenile ossifying fibroma (PsJOF) is a rare benign fibro-osseous lesion characterised to grow to unusually large size very rapidly. Its usual presentation is in younger age group mostly children and predominately involving the Sino-Naso-Orbital region. Its aggressive nature gimmicks a malignant lesion but it is rather a benign lesion with

A Case of Juvenile Psammomatoid Ossifying Fibroma on Skull Base

Journal of Craniofacial Surgery, 2018
Abstract Juvenile psammomatoid ossifying fibroma (JPOF) is a rare tumor that occurs in maxillary sinus or orbit. Complete removal is required due to the aggressive and locally destructive nature. It is hard to distinguish from psammomatoid meningioma in cranial lesion and to remove completely.

Psammomatoid juvenile ossifying fibroma: case study and a review

Oral and Maxillofacial Surgery, 2013
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.
