Primary hyperparathyroidism is rare in children. This report describes a 15-year-old boy who had an intrathymic chief cell adenoma. The literature related to this condition in neonates and children is reviewed. Neonatal hyperparathyroidism differs from hyperparathyroidism in children. The severity of symptoms and osseous lesions, genetic inheritance in many, pathological changes in the parathyroid glands and the need for more extensive treatment in neonates and infants indicate that primary hyperparathyroidism in these patients should be considered as a different entity from that occurring in older children.

A case of primary hyperparathyroidism in an 11-year-old boy who presented with bowlegs is reported and the literature is reviewed. From the literature, it appears that the pathologic findings, clinical manifestations and sex distribution of primary hyperparathyroidism is different in adults than in children and young infants. In adults, primary hyperparathyroidism is commonly caused by adenoma and is often found unexpectedly on a biochemical screen of the serum. Elderly women are most at risk. Renal stones or other renal complications are more frequently seen in adults than in children. Neonatal hyperparathyroidism is often genetically transmitted and is fatal unless recognized and treated early. The characteristic pathologic change is chief cell hyperplasia of the parathyroid glands. On the other hand, adenoma is the most common pathologic finding in older children. No case of childhood parathyroid carcinoma was found in our review of the literature. In children, primary hyperparathyroidism is more frequent in boys than in girls and osseous lesions are more common than in adults. Prognosis is good if the disease is recognized early and appropriate surgical treatment is received.
