osteitis fibrosa cystica is the classic patognomonic form of skeletal disease in hyperparathyroidism that characterizes with decreased cortical bone thickness compared to increased cancellous bone. we present a case of 52-year old female patient with osteolysis of the left calf on radiographic images. the bone scan detected multiple focal pathological accumulations in the skull, left tibia, bot...

Little has been added to the knowledge of the treatment of renal rickets since the paper by Graham and Oakley (1938), and the reader is referred to their work for a summary of the previous literature of this condition. Whether or not in fact rickets is the principal bony lesion has been questioned by Langmead and Orr (1933). From a morbid anatomical study, they concluded that osteitis fibrosa w...

During the hemodialysis treatment of 543 uremic patients for 10 years, significant complications concerning metabolic calcium disturbances, subperiosteal resorption, calcification of soft tissue or peripheral vessels, and fractures were noted. Significant elevation of alkaline phosphatase was induced for 5 years under hemodialysis using 5.0--6.0 mg/dl dialysate calcium, but not under 7.5 mg/dl ...

INTRODUCTION Brown tumors are a rare focal manifestation of osteitis fibrosa cystica, which results from hyperparathyroidism. Chronic kidney failure may lead to secondary or tertiary hyperparathyroidism and thus to osteitis fibrosa cystica and brown tumors. CASE PRESENTATION A 60-year-old man with a history of diabetes mellitus and chronic kidney failure presented with a 15-day history of dys...

Objective. The brown tumour of hyperparathyroidism is a result of a metabolic disorder caused by primary hyperparathyroidism. Report. We described a case of a 37-year-old female patient presenting bimaxillary intraoral lesions and swelling in the neck. Incisional biopsy of the oral lesion was performed and histopathological examination revealed a central giant cell lesion composed by intense ha...

BACKGROUND Primary hyperparathyroidism is an endocrinopathic condition characterized by hypersecretion of parathyroid hormone. Excess parathyroid hormone results in an altered state of osseous metabolism involving bone resorption and tissue change known as osteitis fibrosa cystica, which is the end stage of primary hyperparathyroidism. Osteitis fibrosa cystica is associated with the development...

Increased calcium and phosphorus excretion(Aub et al., 1929, Robertson, 1942) as well as decalcification of the skeletal system(Koppen, 1892; Plummer, 1928; Dunlap and Moor, 1929; Hunter, 1930; Askanazy and Rutishauser, 1933; Martos, 1938; Bartels and Haggart, 1938; Brunner, 1940; Stanley and Fazekas, 1949: Nielsen, 1952; Rose and Boles, 1953; Laake 1955; Epstein et al. 1958)has been frequently...
