Psammomatoid Ossifying Fibroma

Archives of Ophthalmology, 1986
Fibro-osseous lesions represent a variety of bone proliferations each characterized by different morphologic patterns of osteoid production. Psammomatoid ossifying fibroma (POF) is characterized histologically by numerous small round ossicles resembling psammoma bodies and is a locally invasive lesion of facial and cranial bones.

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 ...

The multidisciplinary management of psammomatoid ossifying fibroma of the orbit

Ophthalmology, 1998
To discuss the multidisciplinary management of psammomatoid ossifying fibroma (POF) of the orbit and to clarify the clinicopathologic terminology.The authors present a cohort of cases of POF involving the frontal and ethmoid sinuses and the orbit and discuss the nomenclature and literature.Three patients with POF and their treatment are discussed ...

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

Psammomatoid ossifying fibroma.

Rhinology, 2004
Psammomatoid ossifying fibroma (POF) represents a unique subtype of fibro-osseous lesions. We describe a case of POF involving the orbit and the sinonasal tract, in a 13-year-old white female. Diagnosis depends on the histological, radiological and clinical features. Complete excision by endoscopic nasal surgery was the treatment of choice.

Extensive Neglected Psammomatoid Ossifying Fibroma With Craniofacial Deformity

Journal of Craniofacial Surgery, 2004
The psammomatoid ossifying fibroma is a rare and aggressive lesion that usually arises from the sinonasal region. The lesion is well circumscribed with the pathognomonic feature of concentric or laminated spherical ossicles that appear similar to psammoma bodies.

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.
