Sporadic primary hyperparathyroidism with multiple parathyroid adenomas

Multiple lesions of the parathyroid glands (PTG) in primary hyperparathyroidism (PHPT) can be sporadic or develop as part of hereditary syndromes, manifesting at young age. There the description of a severe sporadic PHPT with big parathyroid neoplasms in the young patient is presented. Clinical data made it possible to suspect MEN-1 syndrome or parathyroid carcinomas; however, mutations CDKN, CDC73, MEN1 were excluded. The patient underwent removal of three identified tumors: benign adenomas of the left PTG and hyperplasia of the right one. Postoperative hypocalcemia and severe hungry bone syndrome required the administration of vitamin D and calcium carbonate preparations. However, a year after the operation, a «mild» recurrent disease was confirmed. Taking into account the patient’s refusal to reoperation and a significant improvement of the target organs state, active observation was continued. The patient needs further careful dynamic monitoring by specialists in order to timely identify indications for repeated surgical treatment to improve the life quality and span.

A clinical case of combined differentiated thyroid cancer and primary hyperparathyroidism: the complexity of topical differential diagnosis

In recent years, the understanding of the epidemiology, symptoms and strategies for managing patients with hyperparathyroidism has changed significantly. The most common cases in clinical practice are of sporadic primary hyperparathyroidism, which today ranks third in prevalence among endocrine diseases (the frequency of occurrence in the adult population is, on average, 12%). In primary hyperparathyroidism, solitary parathyroid adenoma is detected in up to 85% of all cases. The only treatment is radical surgical removal of pathologically altered parathyroid tissue. Early diagnosis and treatment of hyperparathyroidism makes it possible to avoid severe lesions of the skeletal bones and visceral organs. A diagnostically challenging clinical case of a combined onco-endocrine pathology in a 70-year-old patient is presented. The main difficulties in the initial diagnosis were associated with the absence of pathognomonic symptoms of the disease, which was often completely asymptomatic. The most urgent problem appears to be the topical diagnosis of pathologically altered parathyroid glands. Therefore, there is a need to develop an algorithm for the combining and sequential use of existing medical imaging methods.
