Pheochromocytoma in children: 15 cases.

Pheochromocytoma is an uncommon tumor in childhood; nevertheless, 20% of all pheochromocytomas are found in the pediatric population. Fifteen children have been treated in our institution from 1962 to 1990. One percent of patients referred over the same period for investigation of high blood pressure were found to have a pheochromocytoma. The majority of patients have hypertension. It varies in intensity and is paroxysmal in about half the patients. Many pediatric cases of unilateral, bilateral, extra-adrenal, familial, and recurrent pheochromocytomas have been reported. We reviewed our 28 years experience with this tumor and concentrated on the diagnosis, the preoperative and operative management, and the occurrence of the multiple endocrine neoplasia syndromes.
