Primary hyperparathyroidism (PHP) is the third most common endocrine disorder. We report the case of a 28-year-old woman who experienced general weakness, hyperemesis gravidarum and hypercalcemia at 11 weeks of gestation. Corresponding to hypercalcemia, we found inappropriately elevated parathyroid hormone levels. Through neck computed tomography a solitary adenoma of the parathyroid gland, measuring 6 × 2.9 × 11 mm has been documented. An ultrasound-guided fine needle aspiration from the mass confirmed the suspicious of a benign tumor. Left superior parathyroidectomy resulted in immediate and permanent resolution of hypercalcemia. The postoperative course was uneventful. Histopathological and immunohistochemical analyses were consistent with parathyroid adenoma. The diagnostic approach to hypercalcemia in pregnancy represents a challenge for multidisciplinary teamwork.
