Abstract

Parathyroid carcinoma is a rare cause of primary hyperparathyroidism amongst children, with only nine previously reported cases. The objective of the study was to present the first pediatric case with a germline CDC73 (formerly known as HRPT2) mutation, and to review the literature. A 14-year-old girl presented with pathologic slipped capital femoral epiphysis (SCFE). The patient was noted to have an elevated calcium level of 3.4 mmol/L (13.4 mg/dL), a parathyroid hormone (PTH) level of 1013 ng/L (1013 pg/mL), and a 3-cm palpable neck mass. Ultrasound and 99mTc-Sestamibi confirmed the suspicion of a parathyroid mass. Intraoperative findings and pathology confirmed the diagnosis of parathyroid carcinoma. Post-operative PTH decreased to 14 ng/L (14 pg/mL). Genetic testing showed a germline 70 G>T HRPT2/CDC73 mutation. This is the first case documenting a germline 70 G>T HRPT2/CDC73 gene mutation in a pediatric parathyroid carcinoma. Patients with sporadic parathyroid carcinoma may benefit from HRPT2/CDC73 gene mutation screening.
