Introduction: The most common causes of hypercalcemia are primary hyperparathyroidism and malignancy. Malignancy-related hypercalcemia occurs in approximately 20% - 30% of all cancer patients during their clinical course and mainly affects patients with solid tumors such as breast carcinoma.Case Report : 57 yrs old woman was referred for hypercalcemia and osteoporosis. Laboratory: calcium 2.8 mmol/l (normal range 2.15 - 2.55) calculated ionized calcium 1...

Introduction: Parathyromatosis is a rare cause of recurrent hyperparathyroidism defined as small nodules of hyperfunctioning parathyroid tissue in the soft tissues of the neck or mediastinum. The most common cause is probably the implantation of parathyroid cells into surrounding tissue during surgery and the risk of parathyromatosis increases with repeated parathyroid surgery. There is an overlap in the histologic features in parathyromatosis, atypical adenoma, and parathyroi...

Background: Primary hyperparathyroidism can occur at any age, the typical patient is a postmenopausal woman, primary hyperparathyroidsim is found rare by pregnant women. The maternal symptoms are similar to the symptoms by postmenopausal women.Materials and methods: Among the years 2000-2022 we have performed 3459 operations (including 6,6% reoperations) with diagnosis of hyperparathyroidism, there were six women, who underwent parathyroidectomy during p...

Introduction: Familial and hereditary forms of primary hyperparathyroidism (PHPT) represent a small minority of all patients with PHPT (5 – 10%). The surgical approach is different in such cases than in sporadic PHPT. Hereditary PHPT may be syndromic (multiple endocrine neoplasia: MEN – type 1, 2A or 4 and others) or nonsyndromic (familial isolated PHPT). The aim of the study was to identify and describe hereditary and familial forms of PHPT in patients referred to p...
