Primary hyperparathyroidism in a woman with multiple tumors: A case report

BACKGROUND Parathyroid adenoma (PTA) is known as an adenomatous hyperparathyroidism syndrome. At earlier times, the major symptoms of this disease included high blood calcium and low phosphorus. PTA is a benign neuroendocrine neoplasm. We have reviewed the literature and found that it is rare for patients with hyperparathyroidism to have benign tumors with multiple organs at the same time. This report describes a patient with a PTA and four nonfunctional adenomas. CASE SUMMARY We report a case of primary hyperparathyroidism in a 39-year-old woman with multiple organ tumors. The patient was admitted to hospital because of hypercalcemia. Laboratory, imaging, and histological examinations confirmed a left parathyroid neoplasm. Right thyroid adenoma was discovered during hospitalization. She had a medical history of uterine fibroids, right benign mammary gland tumor, and meningioma. The patient recovered after surgical and conservative treatments. CONCLUSION Primary hyperparathyroidism with multiple organ tumors is uncommon, and further studies should be conducted to determine if there is genetic heterogeneity.
