Fibrous dysplasia (FD) is an uncommon, but well-known benign skeletal disorder. In cases affecting long bones, FD is commonly recognized to locate in the diaphyses or the metaphyses and to spare the epiphyses. In this paper, we present a rare case of polyostotic FD in a 13-year-old girl with unilateral multiple epiphyseal lesions arising in the femur, the tibia, and the fibula with the growth p...

Fibrous dysplasia (FD) is a common benign intramedullary lesion of the skeleton characterized by proliferation of fibro-osseous tissue. It is viewed as a developmental abnormality that is typically seen in adolescents and young adults. The lesion is usually asymptomatic and many times discovered as an incidental finding. Exophytic FD is an extremely rare variant that has to be differentiated fr...

Chronic untreated fibrous dysplasia of the mandible in a 40-year-old man is described, with emphasis on the radiographic findings. To the authors' knowledge, this is the first such case to be reported in the literature. Within this mature mandibular lesion, a large radiolucency was noticed, with the appearance of a simple bone cyst. The patient did not have any symptoms directly related to the ...

Three cases of craniofacial fibrous dysplasia are reported, all presenting to the ophthalmologist first. They all had ocular complications due either to direct involvement of the orbital bones or to secondary complications. Sphenoidal mucocele is added to the other complications previously reported, and accordingly a classification of the various ways that fibrous dysplasia can affect the ocula...

Benign tumours of the bone are not cancerous and would not metastasise to other regions of the body. However, they can occur in any part of the skeleton, and can still be dangerous as they may grow and compress healthy bone tissue. There are several types of benign tumours that can be classified by the type of matrix that the tumour cells produce; such as bone, cartilage, fibrous tissue, fat or...

Juvenile ossifying fibroma (JOF) is a rare, benign, locally aggressive entity of the extragnathic craniofacial bones with a high tendency towards recurrence. Two distinctive microscopic patterns of juvenile ossifying fibroma have been described: a trabecular juvenile ossifying fibroma (TrJOF) and a psammomatoid juvenile ossifying fibroma (PJOF). Psammomatoid variant is predominantly a craniofac...
