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.

Transcranial resection of a large sinonasal juvenile psammomatoid ossifying fibroma

Child's Nervous System, 2009
Juvenile psammomatoid ossifying fibroma (JPOF) is a benign but potentially locally aggressive fibroosseous lesion predominantly arising in the paranasal sinuses in children and young adults. Intracranial extension is rare but occurs sometimes. In such cases, tumor resection may often require the combination of neurosurgical and facial approaches ...

Juvenile psammomatoid cemeto‐ossifying fibroma: Two cases

Basic and Applied Pathology, 2010
ABSTRACTJuvenile ossifying fibroma is a variant of ossifying fibroma, commonly involving sinunasal tract of children. It is an aggressive condition that leads to the destruction of adjacent structures. Distinction from other fibro‐osseous lesions is important.

Distinguishing the indistinct: a comparative clinicopathologic and radiologic analysis of cemento-ossifying fibroma, psammomatoid ossifying fibroma, and juvenile trabecular ossifying fibroma”

Oral and Maxillofacial Surgery
Benign fibro-osseous lesions (BFOLs) of the jaws are characterized by the replacement of normal bone with fibrocellular stroma and mineralized material, including bone and cementum-like tissue. Their overlapping radiological and histopathological features often present diagnostic challenges. Recent WHO classifications have refined their categorization,
