title: [Primary hyperparathyroidism in 2 adolescents].
abstract: The authors report on two cases of primary hyperparathyroidism (PHP) in adolescents. In a 15-year-old boy, the clinical picture included skeletal, dental, renal and psychological manifestations. In the second case, the first symptom was urolithiasis at age 12; following a period without any important clinical event, the diagnosis was established when the patient was 18. In both cases, increased calcium and low phosphorus plasma levels associated to moderately elevated plasma parathyroid hormone levels were noted. CT scan and ultrasounds were normal but MRI showed an enlarged gland in the second case. The surgical exploration of the neck revealed an adenoma in the first case and a hyperplastic gland in the second one. Surgery was followed by an immediate improvement of both clinical and laboratory findings. These observations bring us to examine the spectrum of PHP in childhood, the difficulties in biological diagnosis and localizing techniques, and the recent results of surgical treatment.
