Mixed glandular neuroendocrine carcinoma of the endometrium with hypercalcemic crisis.

Objective: To explore the ideas and research progress in diagnosing and treating hypercalcemic crisis in patients with cancer.

Methods: We reviewed the clinical data, diagnosis and treatment of hypercalcemic crisis in a patient with mixed glandular neuroendocrine carcinoma of the endometrium.

Results: The patient had gastrointestinal symptoms and acute renal impairment as the main manifestations, and the blood biochemical indexes suggested a hypercalcemic crisis with elevated parathyroid hormone (PTH). No lesions were seen in the parathyroid glands on imaging and nuclide imaging, but an abnormal pelvic mass was seen in the pelvis and the biopsy of the uterine cervix tissue suggested that it was an adenocarcinoma. Surgery was performed to remove the mass, and postoperative findings suggested endometrial large-cell neuroendocrine carcinoma with endometrioid adenocarcinoma. The calcium and PTH decreased to normal after surgery and chemotherapy.

Conclusions: The condition of the hypercalcemia crisis is dangerous, so it is necessary to think from different aspects of the clinical diagnosis and treatment.
