Effective long-term management of parathyromatosis-related refractory hypercalcemia with a combination of denosumab and cinacalcet treatment.

Parathyromatosis is a rare cause of persistent or recurrent primary hyperparathyroidism and hypercalcemia due to the presence of hyperfunctioning foci of parathyroid tissue in the neck and/or mediastinum. We describe the case of a male patient who presented with severe hypercalcemia and a left-sided palpable parathyroid mass. Over the course of the next 18 years, the patient underwent neck exploration surgery on multiple occasions due to recurrent primary hyperparathyroidism and refractory hypercalcemia, complicated by nephrolithiasis and impairment of renal function, while bone mineral density was preserved.

Recombinant human thyrotropin-aided radioiodine therapy in tracheal obstruction by an invading well-differentiated thyroid carcinoma.

Papillary thyroid carcinomas (PTCs) usually extend to lymph nodes in the neck and mediastinum. Rarely, they invade the neighboring upper airway anatomical structures. We report a 56-year-old woman who presented with symptoms of upper airway obstruction.

Value of the cervical compartments in the surgical treatment of papillary thyroid carcinoma.

In the treatment of papillary thyroid carcinoma (PTC), supplementary lymph node dissection (LND) is not well standardized. The purpose of this study was to evaluate the significance of the cervical compartments in the lymphatic spread of PTC and the impact of modified radical neck dissection (MRND) as an additional surgical procedure to thyroid resection. From 1999 to 2002, LND of the central compartment (compartment A) was performed in 39 patients.
