McCune-Albright syndrome is a rare sporadic disease characterized by bone fibrous dysplasia, café-au-lait skin spots and a variable association of hyperfunctional endocrine disorders. Fibrous dysplasia (FD), which can involve the craniofacial, axial, and appendicular skeleton, may range from an isolated, asymptomatic monostotic lesion to a severe disabling polyostotic disease involving the entire skeleton. A twenty-five-year old male patient presented to our clinic with recently developed heart palpitations...

We describe a case of a paediatric patient affected by mandibular fibrous dysplasia (FD) with severe and chronic pain who was successfully treated with zoledronic acid (ZOL): a third-generation bisphosphonate. Further research is needed to assess its safety and efficacy as a treatment option for FD in the paediatric population.

Fibrous dysplasia is a rare genetic bone disorder with a wide variation in clinical expression, ranging from asymptomatic patients to severely affected patients with extensive bone disease, pain, repetitive fractures and deformities and serious endocrinological symptoms (McCune-Albright syndrome). Here, we report on three different cases of fibrous dysplasia. First, a 46-year-old woman with a small solitary lesion in the proximal femur. Second, a 25-year-old man with polyostotic disease of the left leg who received both surgical and medical treatment...

McCune-Albright syndrome (MAS) is a rare bone disorder characterized by fibrous dysplasia (FD), endocrinopathies, and café-au-lait patches. FD patients have been shown to respond favorably to treatment with bisphosphonates, but data are scarce in the more severe polyostotic form (PFD), including MAS, and factors determining treatment outcome are not known, particularly in the long-term. We evaluated the biochemical (bone turnover markers [BTMs]) and clinical (pain reduction) outcome of bisphosphonate therapy in 11 patients with MAS and 30 patients with PFD: median duration of treatment 6 years (range, 2 to 25 years)...

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...

BACKGROUND: Contouring is a minimal invasive procedure to remove excess lesions and restore facial appearance of patients with craniofacial fibrous dysplasia; however, it is difficult to measure the amount of excess lesions. This study is to demonstrate the use of reduction template produced by three-dimensional printer in contouring procedure. METHODS: Computed tomography data were reconstructed into a three-dimensional model by Mimics software. The unaffected side was mirrored and superimposed on the affected side...

Fibrous dysplasia (FD) is a rare bone disease caused by postzygotic somatic activating mutations in the GNAS gene, which lead to constitutive activation of adenylyl cyclase, and elevated levels of cyclic AMP, which act on downstream signaling pathways, and cause normal bone to be replaced with fibrous tissue and abnormal (woven) bone. The bone disease may occur in one bone (monostotic), multiple bones (polyostotic), or in combination with hyperfunctioning endocrinopathies and hyperpigmented skin lesions (in the setting of McCune-Albright Syndrome)...

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 growing mass. Both cases highlight the importance of recognizing this type of tumor in young patients with abnormal uptake in paranasal bones and sinuses within the range of potential differential diagnoses including sarcomas, fibrous dysplasia, and odontogenic tumors...

BACKGROUND: Fibrous dysplasia (FD) is a benign fibro-osseous lesion related to an abnormal bone development and replacement by fibrous tissue. FD has three clinical patterns namely monostotic, polyostotic, and the McCune-Albright syndrome (MAS). MAS is a rare genetic disorder (about 3% of all FD's) that comprises a triad of polyostotic FD, café-au-lait skin macules, and precocious puberty. MAS can involve the orbit region and cause stenosis in the optic canal, leading the patient to a progressive visual loss...

Fibrous dysplasia of bone is a benign, uncommon, sporadic, congenital skeletal disorder resulting in deformity. This disease arises from activating somatic mutation in GNAS which encodes the α subunit of the G stimulatory protein associated with proliferation of undifferentiated osteogenic cells resulting in marrow fibrosis, abnormal matrix production, and stimulation of osteoclastic resorption upon overproduction of IL-6 observed in dysplastic cells. Fibrous dysplasia may be monostotic or polyostotic. This mutation affecting many tissues, café au lait skin macules and endocrinopathies (precocious puberty, hyperthyroidism, growth hormone excess, Cushing syndrome) may be associated in McCune-Albright syndrome, but also myxoma in Mazabraud syndrome or phosphate diabetes...

Fibrous dysplasia (FD) is a benign, pathological development of bone. Craniofacial bones are the most commonly involved and can potentially cause visual disturbance, proptosis, orbital dystopia, and facial deformity. This case involves a 13-year-old girl with significant proptosis (20 mm left, 17.5 mm right) and downward displacement of the left globe (1.5 mm) due to fibrous dysplasia. Reconstruction was performed with computed tomography-derived and 3D printed custom polyetheretherketone (PEEK) implantation...

Various forms of bony deformations and dysplasias are often present in the facial skeleton. Bone defects can be either localized or general. Quite often they are not only present in the skull but also can be found in other parts of the skeleton. In many cases the presence and levels of specific bone markers should be measured in order to fully describe their activity and presence in the skeleton. Fibrous dysplasia (FD) is the most common one in the facial skeleton; however, other bone deformations regarding bone growth and activity can also be present...

Fibrous dysplasia is a benign fibroosseous bone dysplasia that can involve single (monostotic) or multiple (polyostotic) bones. Monostotic form is more frequent in the jaws. It is termed as craniofacial fibrous dysplasia, when it involves, though rarely, adjacent craniofacial bones. A 16-year-old girl consulted for a painless swelling in the right posterior mandible for two years. Panoramic radiography revealed ground-glass ill-defined lesions in the three different regions of the maxilla and mandible. Axial CT scan (bone window) showed multiple lesions involving skull base and facial bones...

Fibrous dysplasia (FD) is a benign bone disorder characterized by alteration in bone morphology. Monostotic FD is the commonest variant and affects the craniofacial bones. Raynaud's phenomenon is recurrent vasospasm of the fingers and toes due to cold exposure. The disease is usually idiopathic or secondary to connective tissue disorders. Raynaud's phenomenon is not described previously with FD. We recently encountered two interesting patients of craniofacial monostotic FD with Raynaud's phenomenon and report the same in this report...
