Fibrous dysplasia is classified among benign bone tumors. It is a bone development anomaly characterized by hamartoma proliferation of fibrous tissue within the medullary bone, with secondary bony metaplasia, producing immature, newly formed and weakly calcified bone, without maturation of the osteoblast. It can be monostotic or polyostotic. The craniofacial localization occurs in 10%-25% of ca...

INTRODUCTION Involvement of the spinal column in either monostotic or polyostotic form is rare, with fewer than thirty-five cases discussed in the literature. Most of the cases of polyostotic fibrous dysplasia of spine have involvement of the appendicular skeleton. CASE REPORT We report a case of a 74-year-old Irish man with a two month history of back pain. Investigations revealed a diagnosi...

Fibrous dysplasia (FD) is a benign intramedullary fibroosseous lesion originally described by Lichtenstein in 1938 and by Lichtenstein and Jaffe in 1942. 1 This is a benign dysplastic process of altered osteogenesis that may occur within a single bone (monostotic) or multiple bones (polyostotic), 2 and is best understood as a dysplastic anomaly of bone forming mesenchymal tissue. 3 It is a spor...

Fibrous dysplasia is a benign bony abnormality that may be monostotic or polyostotic and is not included in the differential diagnosis of chest pain and dyspnea, since it is typically asymptomatic. A 36-year-old man presented with left-sided chest pain and dsypnea for three months. Chest X-ray and chest computed tomography scan revealed a large solid mass arising from the anterior parts of the ...

The syndrome of McCune-Albright syndrome (MAS) is clasically defined as a triad presentation with the findings of polyostotic fibrous dysplasia, café-au-lait spots, and sexual precocity. However, not all patients present with complete symptoms. A 52-year-old man was diagnosed as having a variant of McCune-Albright syndrome with the following findings: polyostotic fibrous dysplasia, acromegaly d...
