Background The aim of this retrospective study was to investigate pheochromocytoma (pheo), which is a rare endocrine tumor in the pediatric population. Methods The medical records of five children with pheo were studied. The age, gender, clinical presentation, family history, physical findings, coexisting pathology, laboratory evaluation, surgical treatment, and postoperative course were investigated. Results The patients were four girls and one boy with a mean age of 13.2 years (range, 9.57–15.95 years). None of the patients had paroxysmal hypertension and one had normal blood pressure. No malign pheo was identified. Mean height and weight standard deviation scores (SDS), body mass index (BMI), and BMI SDS were −0.24, 0.04, 20.9 kg/m 2 , and 0.20 at the time of diagnosis, and 0.03, 0.43, 23.8 kg/m 2 and 0.49 1 year after operation, respectively. BMI increased significantly after operation. Three patients had normal epinephrine and metanephrine, but elevated norepinephrine and normetanephrine on 24 h urine. Vanillylmandelic acid on 24 h urine sample was elevated in all patients. Ultrasonography failed to visualize tumors in two patients with bilateral pheo. One patient had postoperative severe hypotension. Insulin resistance associated with severe acanthosis nigricans observed in one patient regressed postoperatively. Conclusions Pheo in children may present with different symptoms and findings. Decreased catecholamine in the postoperative period may lead to weight gain.
