01/01/1986 - "The most significant complication of elevated parathyroid hormone (PTH) levels in uremia is the development of osteitis fibrosa cystica. "
01/01/2015 - "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. "

03/01/1975 - "When the patient was first seen at Memorial Hospital in 1931, the diagnosis of osteitis fibrosa cystica was made; serum calcium was 14 mg/100 ml. In 1932, 6 years after Mandl performed the first parathyroidectomy ever for osteitis fibrosa cystica, this patient's neck was explored, and a right hemithyroidectomy was done, with removal of two normal parathyroid glands. "
10/01/1993 - "This case illustrates that normalizing serum calcium prior to surgery in patients with primary hyperparathyroidism and osteitis fibrosa cystica can be highly beneficial."

07/01/1998 - "Roentgenologic evidence of hyperparathyroidism with osteitis fibrosa cystica and a high product of the calcium and phosphate values were indications for the parathyroidectomy. "
05/29/2007 - "Nowadays, the occurrence of brown tumor lesions or osteitis fibrosa cystica caused by long-lasting primary hyperparathyroidism are very rare, since measuring serum calcium became available routinely in the mid-1970s. "

01/01/1989 - "To test this hypothesis, a patient having hypercalcemic PHPT with florid osteitis fibrosa cystica and normal serum 1,25(OH)2D was given increasing daily doses of intravenous calcitriol (0.5-2 micrograms) for several days. "
01/01/1989 - "A marked direct suppression of primary hyperparathyroidism with osteitis fibrosa cystica has been achieved by the intravenous administration of 1,25-dihydroxycholecalciferol [1,25(OH)2D]. "

01/01/1989 - "In a recent survey of 306 patients with primary hyperparathyroidism (PHPT), we hypothesized that the far higher degree of parathyroid hormone (PTH) hypersecretion in PHPT with osteitis fibrosa cystica than in PHPT without overt bone disease might be due to the absence of suppression of hormonal hypersecretion by the low-to-normal circulating 1,25(OH)2D reflecting a relative vitamin D deficiency. "
11/01/1980 - "Serum concentrations of 1,25-dihydroxyvitamin D [1,25-(OH)2D] and immunoreactive parathyroid hormone were measured before and for 7 months after the removal of a 15-g parathyroid adenoma from a 44-yr-old woman with primary hyperparathyroidism and severe osteitis fibrosa cystica. "

11/01/1984 - "She had hypocalcemia, hyperphosphatemia, elevated alkaline phosphatase and parathyroid hormone levels, and normal vitamin D metabolite levels, with osteitis fibrosa cystica on bone biopsy specimen. "

10/01/1993 - "Serum alkaline phosphatase also rose from 309 to 390 units/l (normal range, 25-97), suggesting the beginning of resolution of her osteitis fibrosa cystica prior to surgery. "
11/01/1984 - "She had hypocalcemia, hyperphosphatemia, elevated alkaline phosphatase and parathyroid hormone levels, and normal vitamin D metabolite levels, with osteitis fibrosa cystica on bone biopsy specimen. "

10/01/1996 - "We conclude that 1) the hypercalcemia due to constitutive overactivity of the PTH/PTHrP receptor is indistinguishable from that of mild primary hyperparathyroidism in clinical characteristics and renal tubular and skeletal features; and 2) the classic laboratory manifestations of primary hyperparathyroidism, with the possible exception of osteitis fibrosa cystica, can all be accounted for by overactivity of a single receptor."

03/01/1985 - "In an effort to investigate the utility of immunostaining for S-100 protein in the differential diagnosis of chondroblastoma, the expression of S-100 protein in nine chondroblastomas was compared with that in six giant cell tumors, six aneurysmal bone cysts, four giant cell reparative granulomas, six cases of fibrous dysplasia, two cases of osteitis fibrosa cystica, two nonossifying fibromas, and one clear cell chondrosarcoma. "

07/01/2008 - "CT-guided FNA of a lesion revealed bland histiocytic and spindled cells, prominent hemosiderin pigment and scattered multinucleated cells, findings consistent with osteitis fibrosa cystica. "
