Juvenile psammomatoid cemeto Ossifying Fibroma two cases
Basic and Applied Pathology, 2010Co-Authors: Ja Hee Seo, Doo Hee Han, Chaeseo Rhee, Sung Hye ParkAbstract:Juvenile 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. Juvenile Ossifying Fibroma has two histologic subtypes that are psammomatous and trabecular type. We present herein two cases of Juvenile psammomatoid Ossifying Fibroma occuring in a 22 month old and a 5 year old child, which arose in the bilateral maxillary sinuses and led to bulging of the cheek and nasal obstruction. The tumor in case 1 could not be completely excised due to its huge size and massive destruction of the bilateral maxilla. The tumor in case 2 was completely excised through staged operations. Tumors in both cases were diagnosed as Juvenile pammomatoid cement-Ossifying Fibroma by the histology. Here, we report two cases from Korea and describe psammomatoid morphology and how to differentiate it from other fibro-osseous lesions.

two stage surgical treatment for a giant sellar psammomatoid Juvenile Ossifying Fibroma case report
Journal of Neurosurgery, 2019Co-Authors: Spencer Twitchell, Michael Karsy, Yair M Gozal, Christian Davidson, William T Couldwell, Douglas L BrockmeyerAbstract:Psammomatoid Juvenile Ossifying Fibroma (PJOF) is an uncommon, benign fibro-osseous tumor. It is a purely surgical disease, and a review of the literature revealed that adjuvant therapies, including chemotherapy and radiation, play a limited role. The authors report the case of a 16-year-old male refugee who presented with a giant sinonasal PJOF with parasellar invasion, after having been unable to undergo earlier surgical treatment. The delay in presentation resulted in a large lesion with bilateral optic nerve compression, blindness, and frontal lobe compression. The patient was surgically treated with a two-stage combined cranial and endoscopic endonasal surgical approach. The delay in treatment and significant neurological compromise, which necessitated a two-stage approach, are unique from previously reported cases of PJOF.

trabecular Juvenile Ossifying Fibroma with aneurysmal bone cyst a rare presentation
Pediatric Dentistry, 2011Co-Authors: Carolina Amalia Barcellos Silva, Alessandra Dutra Da Silva, J A Soares, Cristiane FuruseAbstract:Abstract Juvenile Ossifying Fibroma is an uncommon, benign, bone-forming neoplasm that is distinguished from other fibro-osseous lesions primarily by its age of onset, clinical presentation, and potential behavior. It mainly occurs in Juveniles and has a slight male predilection and more aggressive behavior than a common Ossifying Fibroma. There are 2 distinct histopathological variants of this lesion: (1) psammomatoid pattern and (2) trabecular pattern. An aneurysmal bone cyst may occur in association with other bone lesions, such as fibrous dysplasia, Ossifying Fibroma, and giant cell lesion. The clinical management and prognosis of Juvenile Ossifying Fibroma is somewhat uncertain, and this tumor has high rates of recurrence. Such behavior may be related to younger patient age and the concurrent development of aneurysmal bone cyst. The purpose of this paper was to report a case of trabecular Juvenile Ossifying Fibroma in a 9-year-old girl associated with an aneurysmal bone cyst, presenting an aggressive behavior, and causing significant facial asymmetry.

psammomatoid and trabecular variants of Juvenile Ossifying Fibroma two case reports
Indian Journal of Radiology and Imaging, 2009Co-Authors: Simi Thankappan, Sherin Nair, Valsa Thomas, K P SharafudeenAbstract:Juvenile Ossifying Fibroma (JOF) is an uncommon fibro-osseous lesion occurring in the facial bones. It is highly aggressive and has a strong tendency to recur. It has been recognized as a separate histopathological entity among the fibro-osseous group of lesions. Surgical resection is the preferred line of treatment. Here we report two cases of JOF who reported to the oral medicine and radiology department; the two cases had different clinical features, history, radiological appearance, and aggressiveness. Under the recent classification system, both cases were recognized as histopathological variants of JOF: one psammomatoid and the other trabecular.
