BACKGROUND There is a common pathologic relationship between parathyroid adenoma and thyroid cancer, but this relationship is infrequent in pregnant patients with primary hyperparathyroidism (PHPT). CASE SUMMARY A 27-year-old gravida 1 woman was transferred to our hospital at 16 wk of pregnancy. She was diagnosed with parathyroidoma, papillary carcinoma of the thyroid and thyroid adenoma and was managed surgically. Both the mother and the newborn were stable after a right inferior parathyroidectomy and total thyroidectomy. The healthy infant was delivered at the 40th week of pregnancy. The mother had no evidence of recurrence over three years of follow-up. CONCLUSION Awareness of concomitant PHPT and thyroid diseases may help in managing patients with a history of hypercalcemia.
