Secondary hyperparathyroidism after total en bloc gastrectomy due to Non-Hodgkin’s lymphoma

Gratiela Bratu , Radulescu Vlad , Stancu Cristina , Badiu Corin

Introduction: Primary hyperparathyroidism is a condition in which one or more parathyroid glands have a pathological secretion of parathyroid hormone due to their abnormal function. Secondary hyperparathyroidism has normal parathyroid glands, but an abnormal secretion of PTH because of an underlying condition that influence their activity. It is important to differentiate between primary and secondary hyperparathyroidism because of the different treatment.<p class="abstext...

One of the main causes of protracted, severe hypocalcemia after parathyroidectomy is hungry bone syndrome (HBS). We report the case of a 40-year-old man who was first admitted to the Endocrinology department of Zemun Clinical Hospital (ZCH) in order to perform a workup for hypercalcemia. Further laboratory and imaging diagnostics indicated that a giant parathyroid adenoma, measuring approximately 6 cm in size, was the cause of the hypercalcaemia. An endocrine surgeon at the Cl...
