Fibrous dysplasia (FD) is a rare fibro-osseous lesion in which normal bone is replaced by abnormal fibrous tissue. Although a congenital disorder, a single case report of traumatic etiology had been described in the literature. We report a case of monostotic FD of the parietal calvarium in a 21-year-old female patient who presented to us with a single swelling in the parietal region been noticed after head injury sustained at the age of 7 years. After imaging investigations, the lesion was excised via craniotomy followed by cranioplasty in the same sitting...

BACKGROUND: Fibrous dysplasia (FD) is a rare benign bone disorder in which the normal bone is replaced by immature fibro-osseous tissue. However, some case reports have reported that FD showed significantly increased (99m)Tc-methylene diphosphonate ((99m)Tc-MDP) uptake on whole-body bone scintigraphy (WBS), which may mimic bone metastasis or skeletal involvement of the patients with known cancer. Thus, the purpose of present study is to observe the reliable characteristics and usefulness of single photon emission computed tomography/computed tomography (SPECT/CT) for the diagnosis of FD...

The latest (4th) edition of the World Health Organization Classification of Head and Neck tumours has recently been published with a number of significant changes across all tumour sites. In particular, there has been a major attempt to simplify classifications and to use defining criteria which can be used globally in all situations, avoiding wherever possible the use of complex molecular techniques which may not be affordable or widely available. This review summarises the changes in Chapter 8: Odontogenic and maxillofacial bone lesions...

Posttraumatic fibro-osseous lesion (PTFOL) is a rare lesion that typically affects the ribs and is probably a posttraumatic reactive process. Because PTFOL is often misdiagnosed as fibrous dysplasia, osteoid osteoma, benign fibrous histiocytoma or rib metastases, chest wall resection, leading to a significant morbidity, is the main treatment modality. We report the case of a 30-year-old male patient with no history of previous trauma presenting with chest pain. Computed tomography scan showed an eighth left rib well-defined ovoid and hypodense lesion with circumferential sclerotic margin and no cortical breakthrough...

OBJECTIVES: Fibrous dysplasia of bone is a rare sporadic benign congenital condition in which normal cancellous bone is replaced by fibro-osseous tissue with immature osteogenesis. Sarcomatous transformation is exceptional. Lesions may involve one bone (monostotic) or several (polyostotic). Fibrous dysplasia may be associated with café-au-lait skin macules and endocrinopathy in McCune-Albright syndrome, or with myxoma in Mazabraud's syndrome. METHODS: We report ten cases of patients followed up for craniofacial fibrous dysplasia in our center between 2010 and 2015...

Florid osseous dysplasia is a rare benign fibro-osseous multiquadrant dysplastic lesion confined to the alveolar process of jaws, generally asymptomatic and usually detected incidentally during radiologic examination and requires no treatment unless symptomatic or cosmetically concerning. In this article, we present two rare cases of florid osseous dysplasia in Indian women with their clinical, radiographic and histologic findings and a brief review of literature. The first case was asymptomatic and the lesion was detected during routine radiographic examination and required no treatment whereas, the second case presented with features of osteomyelitis...

Florid cemento-osseous dysplasia (FCOD) is a rare, benign, multifocal fibro-osseous dysplastic process affecting tooth-bearing areas of the jaw, characterized by replacement of normal trabecular bone with osseous tissue and dense acellular cementum in a fibrous stroma. It is one clinicopathologic variant in a spectrum of related non-neoplastic fibro-osseous lesions known as cemento-osseous dysplasias (CODs), thought to arise from elements of the periodontal ligament. Diagnosis primarily relies upon radiographic and clinical findings; unnecessary biopsy should be avoided, as inoculation with oral pathogens may precipitate chronic infection in these hypovascular lesions...

Fibrous dysplasia of the bone is a developmental benign skeletal disorder characterized by replacement of normal bone and normal bone marrow with abnormal fibro-osseous tissue. We report on a case of a biopsy-proven fibrous dysplasia lesion in the left temporal bone, with intensely increased activity (SUVmax, 56.7) on Ga-DOTATATE PET/CT. The presented data indicate cell surface overexpression of somatostatin receptors by fibrous dysplastic cells and highlight the need of cautious management of Ga-DOTATATE-avid bone lesions, which could mimic malignancy especially in patients with history of neuroendocrine tumors...

The purpose of this case report is to describe a previously unpublished association between focal cemento-osseous dysplasia (FCOD) and an aneurysmal bone cyst (ABC) and review the literature with regard to associated benign fibro-osseous lesions and cysts. A 41-year-old woman without a history of trauma presented with asymptomatic swelling in the right side of the mandible. Radiographs of the region revealed a unilocular radiolucent area with radiopaque foci. After aspiration of the lesion was positive for serosanguineous fluid, complete excision of the lesion was performed...

Fibrous dysplasia (FD) is an uncommon skeletal disorder in which normal bone is replaced by abnormal fibro-osseous tissue. Mainly, FD is found in children, and by adulthood it usually becomes quiescent. Our case showed FD of more than 14-year duration in the left maxilla. Our evaluation was that growth ceased in adulthood and had achieved the static stage. Because FD cases in elderly patients are rarely reported, we hereby present a monostotic FD case in a 65-year-old female. We presented sequential radiographic images and scintigraphic images of this case, and combined them with a literature review that emphasized the progression of the disease...

INTRODUCTION: Fibrous dysplasia (FD) is a non-neoplastic developmental fibro-osseous disease. It represents 2.5% of all bone tumors and 5% to 7% of the benign bone tumors. Orbitocranial region is involved in about 20% of the patients. The main presentations are craniofacial deformity and headache. Loss of vision is the most devastating result of this disease. There is no medical treatment to cure or prevent FD. Radiation therapy is contraindicated. Surgery for the orbitocranial FD is often challenging because of the proximity of neurovascular and ocular structures...

PURPOSE: Different lesions in the fibro-osseous group share microscopic features; thus, establishing a definitive diagnosis based on microscopic features alone can be a challenge. There is a need for additional microscopic tools to aid in differentiating these lesions. This study compared parameters related to vascularity among 3 lesions in the fibro-osseous group: fibrous dysplasia (FD), central ossifying fibroma (COF), and cemento-osseous dysplasia (COD). MATERIALS AND METHODS: This study was a cross-sectional analysis of biopsied lesions retrieved from 3 medical centers over a 14-year period...

INTRODUCTION: Florid osseous dysplasia is a rare and benign fibro-osseous pathology, in which bone is replaced by fibrous tissue and metaplastic bone. It can remain asymptomatic for a long time and is most often discovered incidentally during a radiological examination. Sometimes, patients are seen because of an infectious complication. OBSERVATION: An edentulous 62 years-old woman was referred for a painful mandibular swelling preventing insertion of her removable denture...

Bone dysplasias comprise of a condition where the normal bone is replaced with fibrous tissue. Periapical Cemento-Osseous Dysplasia (PCOD) is a benign fibro-osseous condition where bone tissue is supplanted with fibrous tissue and cementum-like material. This condition affects mostly mandibular anterior region and rarely occurs in the maxilla. PCOD is seen above 30 years of age and has slight female predilection. Generally the teeth related to such lesions appear to be vital and are usually asymptomatic. These lesions are mostly seen during routine radiographic examination whose presentation may vary from complete radiolucency to dense radiopacity...

Cherubism is a rare disorder with autosomal dominant inheritance. It is classified as a benign fibro-osseous lesions and may involve either facial bone. Its typical dentofacial deformities are caused by mutations in the SH3BP2 gene. The protein encoded by SH3BP2 had a significant role in the regulation of osteoblasts and osteoclasts. Accordingly with the radiological findings, differential diagnoses includes fibrous dysplasia, giant cell granuloma, osteosarcoma, juvenile ossifying fibroma, fibrous osteoma, odontogenic cyst and hyperparathyroidism...

Fibrous dysplasia (FD) is a benign fibro-osseous lesion that typically behaves as a painless, slowly expanding tumor. On rare occasion, FD will undergo malignant transformation. When sarcomatous change occurs, osteosarcoma is the typical variant, followed by chondrosarcoma and fibrosarcoma. The incidence of malignant change varies from 1 to 4% depending on whether the disease is mono-ostotic or polyostotic and syndromic (McCune-Albright or Jaffe-Lichtenstein syndrome). Despite the low incidence of malignant change, the potential lethality of this disease behooves treating surgeons to be keenly aware of the signs and symptoms indicative of malignancy...

Osteofibrous dysplasia or ossifying fibroma is an uncommon benign fibro-osseous lesion of childhood, commonly described in the maxilla and the mandible. Among long bones, it usually presents in the tibia as a painless swelling or anterior bowing. Ossifying fibroma of clavicle has never been reported in English literature, to the best of our knowledge. Here, we would like to present an unusual case of osteofibrous dysplasia of clavicle clinically mimicking chronic osteomyelitis.

Benign fibro-osseous lesions of the maxillofacial skeleton constitute a heterogeneous group of disorders that includes developmental, reactive (dysplastic) and neoplastic lesions. Although their classification has been reviewed multiple times in the past, the most common benign fibro-osseous lesions are fibrous dysplasia, osseous dysplasia and ossifying fibroma. For the dental clinician, the challenges involve diagnosis and treatment (or lack thereof). A careful correlation of all clinical, radiologic and microscopic features is essential to establish a proper diagnosis and a clear treatment plan...
