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.
infiltration of the surrounding bone. Multinucleated osteoclast-like giant cells are common. Differentiating it from cemento-ossifying fibroma is usually straightforward as cemento-ossifying fibroma occurs in adult patients, predominantly in the molar/premolar location. Unlike cemento-ossifying fibroma, trabec...
Cemento-ossifying fibroma / ossifying fibroma is a benign fibro-osseous neoplasm that is odontogenic in origin, usually arises in jaw and characterized by production of bone and cementum-like calcifications in a fibrous stroma
Two subgroups, juvenile psammomatoid ossifying fibroma (PsJOF) and juvenile trabecular ossifying fibroma, have been delineated by their histology. PsJOF occurs predominantly in the sinonasal and orbital bones. This work reports on 2 cases of extensive PsJOF in the body of the right mandible as ...
Juvenile Psammomatoid Ossifying fibromaOssifying fibromas of the head and neck region are classified as cemento-ossifying fibroma (COF) (odontogenic origin), and two types of juvenile ossifying fibromas: juvenile trabecular ossifying fibroma (JTOF), and juvenile psammomatous ossifying fibroma (JPOF)...
we report a case of recurrence and malignant transformation of PMT-ossifying fibroma-like subtype in the left hip bone.#Here, we report the clinical manifestations, histology, pathological features, and treatment of a 57-year-old Chinese woman with a recurrent and malignant ossifying fibroma-like ...
Due to the lump enlargement, the patient was admitted to RSCM in July 2019 and had biopsy incision with a diagnosis of cemento ossifying fibroma which was confirmed by the histopathological examination and histology report. The resection of the right part of maxilla was conducted alongside with ...
histologymaxillaradiologyCementoossifying fibroma (COF) is considered a benign osseous tumor, very closely related to other lesions such as fibrous dysplasia, cementifying periapical dysplasia or cemento-osseous florid dysplasia, however forming its own entity according to the 1992 classification of the ...
Hereby, we describe a case of an aggressive ossifying fibroma which presented with extensive mandibular swelling along with its surgical treatment, review of the histology, clinical behavior, and management of these uncommon but disfiguring lesions. Inspite of possessing a benign biological behavior, ...
Juvenile ossifying fibroma is a benign, but potentially aggressive, fibro-osseous tumor of the craniofacial bones. The authors describe a case of a mandibular juvenile ossifying fibroma presenting in a 14-year-old boy in conjunction with congenitally missing teeth and review the histology, clinical ...
