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. The authors are presenting a case of 26-year-old male with JPOF on skull base and report this case with review of literature.

Background: Many studies have reported that macrophages and eosinophils are involved in the pathogenesis of several diseases. To the best of our knowledge, this is the first study comparing macrophages and eosinophils in oral reactive lesions. Aims: In this study, we aimed to determine the contribution of macrophages and eosinophils to the pathogenesis of oral reactive lesions and the relationships between these biomarkers and the diverse histopathologic features...

INTRODUCTION: Reactive hyperplastic lesions develop in response to a chronic injury simulating an exuberant tissue repair response. They represent some of the most common oral lesions including inflammatory fibrous hyperplasia, oral pyogenic granuloma, giant cell fibroma, peripheral ossifying fibroma, and peripheral giant cell lesions. OBJECTIVE: The incidence of those lesions was investigated in an oral pathology service, and the clinical characteristics, associated etiological factors, concordance between the clinical and histopathological diagnostic was determined...

Psammomatoid juvenile ossifying fibroma (PJOF), a variant of juvenile ossifying fibroma (JOF), is a locally aggressive neoplasm of the children and young adults. This entity has predilection for the sinonasal region. It forms a differential diagnosis for many bone neoplasms. We report three cases of PJOF, in young patients whose biopsy showed the presence of psammomatoid bodies in a cellular fibrous stroma. The diagnosis of JOF indicates requirement of extensive surgery due to its locally aggressive nature.

OBJECTIVE: To examine the utility of an endoscopic transseptal approach and the creation of a bilateral nasoseptal flap using a two-nostrils/four-hands technique in patients with challenging skull-base tumors. METHODS: The medical records of patients operated on via an endoscopic transseptal approach between 2009 and 2017 were retrospectively reviewed. Two patients with ossifying fibroma, two with orbital hemangioma, two with trigeminal nerve schwannoma, and one patient each with juvenile angiofibroma, meningioma, and myxofibrosarcoma were included in the study...

OBJECTIVES: The current study aimed to assess CT and MRI characteristics of histological subtypes of head and neck ossifying fibroma (OF). METHODS: 12 patients with histopathologically-proven head and neck OF were included in this study. Lesions were pathologically classified into three histological subtypes: eight cement-OFs (COFs), three juvenile psammomatoid OFs (JPOFs), and one juvenile trabecular OF (JTOF). All patients underwent CT examination, while seven also underwent MRI...

The infiltration by numerous osteoclastic giant cells is a frequent finding in bone tumors and pseudo-tumors. Pathologists must integrate clinical and radiological data to achieve a correct diagnosis in bone pathology. Benign giant-cell rich lesions of bone encompass giant cell tumor of bone, aneurysmal bone cyst, chondroblastoma, brown tumor and fibrous cortical defect/non-ossifying fibroma. Amongst malignant neoplasms, variants of conventional osteosarcoma, undifferentiated pleomorphic sarcoma, leiomyosarcoma and bone metastasis must be discussed...

Osteosarcoma (OS) is a malignant bone tumor and it is very rare in head and neck region. If it arises in this area, most common localizations of this tumor are mandible and maxilla and ethmoid sinus is very rare site for this malignancy. A 43-year-old female admitted to our clinic with the complaint of pain in the right half of the face and headache persisting for 2 months. According to the clinical symptoms and imaging studies, sinonasal ossifying fibroma was suspected. For this reason, patient was operated endoscopically and histopathological examination revealed that osteoid matrix producing atypical osteoblastic cells so these findings identified osteoblastic variant OS...

Mandibular reconstruction after partial or subtotal resection is considered a challenging procedure that is crucial for facial contour and function. Many reports regarding the reconstruction of mandibular defects have been published over the years. The fibula free flap has become a popular option for mandibular reconstruction since its introduction by Hidalgo in 1989. However, the locations of the reconstructed mandibular angle and the condyle of the fibular bone segments play a crucial role in facial symmetry and function...

Juvenile ossifying fibroma (JOF) is a rare benign bone tumor that occurs most frequently in the craniofacial bones of children and young adults. There are few case reports that describe its involvement outside the craniofacial skeleton, especially within the spinal column. While JOF is classified as a benign lesion, it may be locally aggressive and demonstrate a high propensity for recurrence, even after resection. Definitive surgical management may be challenging in naive cases, but it is particularly challenging in recurrent cases and when extensive spinal reconstruction is warranted...

Peripheral osteoma is the most common subtype of osteoma that arises most frequently in the craniofacial bones. It may occur at any age with a male-to-female ratio of 2:1. Peripheral osteoma may affect the mandible, particularly the ramus and the condyle. Compound odontoma is a subtype of odontoma that occurs in young subjects without gender predilection. It affects the maxilla more frequently than the mandible. Focal cemento-osseous dysplasia and cemento-ossifying fibroma are 2 benign fibro-osseous lesions with a female predominance that occur most commonly in the posterior region of the mandible...

The use of the term "fibroma" for any soft-tissue lesion or gingival lesion by general practitioners has led to inadequate diagnosis of quite a few rare entities. The occurrence of gingival lesions in adolescent female patients is a routine clinical finding. The site of occurrence of such a lesion is of prime significance, as the rarity of these lesions is determined by the site and size of the lesion. On the other hand, the dilemma over the diagnosis of peripheral ossifying fibroma (POF) versus peripheral odontogenic fibroma still continues...

The aim of this case series was to reveal the difficulties in diagnosing fibro-osseous lesions with radiological and histopathological examinations and quantify the potential risk of infection to fibro-osseous legions. To analyze the concordance between radiological and histopathological diagnoses, this retrospective case series included patients who were clinically diagnosed with fibro-osseous lesions via radiological findings and excluded the patients who did not undergo histopathological examinations. This study also included the patients in whom histopathological results confirmed fibro-osseous legions when preoperative radiological diagnosis did not include fibro-osseous legions...

REVIEW
Meghan Wilson, Carl Snyderman
Fibro-osseous lesions of the skull base include a variety of lesions with different biologic behavior. The most common lesions include fibrous dysplasia, osteoma, aneurysmal bone cyst, and juvenile ossifying fibroma. The diagnosis can usually be established with radiographic imaging. In the absence of symptoms, slow-growing lesions can often be observed. When surgery is indicated for relief of symptoms, endoscopic endonasal techniques are well suited for all age groups.

Background and Objective: Reactive proliferations of oral cavity comprise pyogenic granuloma (PG), fibrous hyperplasia (FH), peripheral ossifying fibroma (POF), and peripheral giant-cell granuloma (PGCG). They often pose diagnostic challenges due to their overlapping clinical and histopathological features. This study was conducted to determine the frequency and clinicopathological correlation of reactive hyperplastic lesions in the oral cavity reported in our institute and compared it with other previous studies...

BACKGROUND: Ossifying fibroma is a rare benign fibro-osseous lesion seen in the bones of the head and neck area. It is mostly found in the mandible followed by the maxilla and rarely in the paranasal sinuses along with the orbit and skull bones. CASE PRESENTATION: A 30-year-old male patient presented with headache and incidental finding of a right ethmoidal sinus ossifying fibroma by paranasal-sinuses CT scan and MRI of the face. A flexible fiber-optic nasal endoscopy examination revealed a right side fullness...
