Parathyroid tumors are heterogeneous, and diagnosis is often difficult using histologic and clinical features. We have undertaken expression profiling of 53 hereditary and sporadic parathyroid tumors to better define the molecular genetics of parathyroid tumors. A class discovery approach identified three distinct groups: (1) predominantly hyperplasia cluster, (2) HRPT2/carcinoma cluster consis...
Introduction: Hypoparathyroidism is the most frequent complication of thyroidectomy, which influenced by multiple factors, mainly unintentional resection, due to its location, size and difficulty in identification, leading post-surgical hypocalcemia 20 30% 1 3% cases, may be permanent; this techniques have been described for Benmiloud et al. conducted a case-control study where they compared ef...
Parathyroid glands from cases of hyperparathyroidism have been examined with particular attention to mast cells. In ;normal' glands accompanying an adenoma they were common, although there was a wide range in their frequency, whereas in pathological tissue, both adenoma and hyperplasia, mast cells were scarce. This difference between glands was examined with respect to alterations in gland size...
OBJECTIVE To determine the frequency of the types of parathyroid gland hyperplasia and the sensitivity of sestamibi-(99m)Tc (MIBI) scintigraphy and ultrasonography (US) of patients with secondary hyperparathyroidism (SHPT) due to chronic renal failure. MATERIAL AND METHODS We studied 43 patients with SHPT (26 females and 17 males with age range of 27-75 years). Blood tests were performed to d...
The simultaneous occurrence of hyperthyroidism and primary hyperparathyroidism is quite rare. A case is reported here of Graves' disease and primary hyperparathyroidism. Treatment of these concomitant diseases consists in combined thyroidectomy and parathyroidectomy. Histological examination confirmed Graves' disease and revealed the presence of a parathyroid adenoma in one gland and parathyroi...
Primary hyperparathyroidism is present in approximately 1 in 500 people and occurs predominantly in post-menopausal women. The condition occurs in approximately 85% cases as adenoma, 14% cases as Parathyroid Hyperplasia and in 1% cases as Parathyroid Carcinoma (1) . Rarely it can occur as part of MEN (Multiple Endocrine Neoplasia) Type 1 and Type 2a and Familial Hyperparathyroidism. There is al...
