Brown tumor represents a serious and late bony complications of advanced hyperparathyroidism with a frequency of 1.5–1.75 percent in secondary hyperparathyroidism and 3–4 percent in primary hyperparathyroidism. [1,2] Here we describe an extremely rare case of a 19-year-old male patient with a brown tumor localised in the maxilla and mandibular due to secondary hyperparathyroidism compromising m...

The immunoreactive forms of parathyroid hormone (iPTH) in the plasma of six patients with primary, adenomatous hyperparathyroidism and six patients with ectopic hyperparathyroidism due to non-parathyroid cancer were compared by using gel filtration on columns of Bio-Gel P-150 and radioimmunoassay of iPTH in eluted fractions after concentration. We found much less (p<0.001) small (mol wt<9,500) ...

primary or secondary hyperparathyroidism can present with a brown tumor of the mandible. involvement of other skull and facial bones is extremely rare. only a few cases with brown tumor of the orbital bones have been reported. an is year old girl with primary hyperparathyroidism presented with unilateral exophthalmos caused by brown tumor of the orbital roof, lite patient had a 1.5 cm palpable ...

introduction: osteodystrophy is one of the long term complications of chronic renal failure and is expressed in two formslow turn over and high turn over. it is an important cause of morbidity in patients with renal failure and if diagnosed and managed properly, many problems of these patients can be resolved. in this study we evaluated the prevalence of hyperparathyroidism in hemodialysis pati...

Introduction: Hyperparathyroidism is presented with increased parathyroid hormone (PTH) secretion due to hyperfunctioning of one or more of the four parathyroid glands. Primary hyperparathyroidism (p-HPT) can be due to parathyroid adenoma, hyperplasia or carcinoma of the parathyroid gland. Secondary hyperparathyroidism (s-HPT) is usually a response to hypocalcaemia and consecut...

Secondary hyperparathyroidism is an unusual complication of hypophosphatemic rickets during the treatment. As there is growing evidence that a high phosphate diet may induce secondary hyperparathyroidism and even tertiary hyperparathyroidism caused by hyperplasia of the parathyroid glands. Serum calcium, phosphate and also parathyroid hormone should be measured regularly to catch the early diag...

Osteitis Fibrosa Cystica (OFC) is defined as the classic skeletal manifestation of advanced primary hyperparathyroidism. With the increased detection by means of routine calcium screening, the clinical profile of primary hyperparathyroidism in Western countries has shifted from symptomatic disease to one with subtle or no specific symptoms ("asymptomatic" primary hyperparathyroidism). The autho...

Brown tumor is a bone lesion secondary to hyperparathyroidism of various etiologies. Skeletal involvement in primary hyperparathyroidism secondary to parathyroid adenoma is very uncommon and brown tumor has become extremely a rare clinical entity. Hyperparathyroidism is usually associated with high levels of serum calcium. Brown tumor as the only and initial symptom of normocalcemic primary hyp...

the excessive amounts of parathyroid hormone in secondary hyperparathyroidism (shpth) is suggested to interfere with normal erythropoiesis.  in shpth, during chronic renal failure, due to the impairment of erythropoietin synthesis, this effect is more pronounced.  in the present study the role of secondary hyperparathyroidism in the severity of anemia was evaluated in hemodialysis patients (n=3...

Secondary hyperparathyroidism is a common complication for patients with end-stage renal disease (ESRD). When it progresses, it is associated with morbidity and mortality [1]. Phosphate binders and vitamin D can be used to prevent the progression of secondary hyperparathyroidism. However, these conservative treatments often fail to control severe hyperparathyroidism. In such cases, parathyroide...
