The article presents a clinical case of a prolonged course of gastrointestinal ulcer disease, followed by dysphagia. During the examination, severe hyperparathyroidism was revealed, which subsequently prompted a diagnostic search for a parathyroid adenoma, which is the cause of hyperathyroidism in 80–85% of cases. With instrumental methods of research, the cause of the main complaint is dysphagia, a formation in the posterior upper mediastinum up to 5 cm, compressing the esophagus. With transoesophageal aspiration biopsy (EUS-TYPE). The cytological picture is similar to the thyroid epithelium with part of the oncocytic differentiation. In an immunological study, lavage for parathyroid hormone showed high expression. Scintigraphy with Tc-99m pertechnetate revealed the exact topic of the formation of the parathyroid gland in the posterior mediastinum – an atypical location. Surgical treatment was performed in the amount of thoracoscopic removal of the mediastinal tumor. The radical nature of the surgical intervention was confirmed by laboratory. Serum PTH levels decreased significantly. Upon receipt of the morphological conclusion, reliable data on malignant damage to the parathyroid gland were obtained. Subsequent treatment of the patient consisted in the correction of severe hypercalcemia in the postoperative period by prescribing denosumab, which led to the stabilization of the patient’s condition.
