Pheochromocytomas are catecholamine-secreting tumors. These tumors are rare in children, and they may be associated with hereditary syndromes such as von Hippel-Lindau (VHL) disease. Most pediatric patients with pheochromocytoma present with sustained hypertension, while 10% to 69% of adult patients are asymptomatic. Herein, we present the case of a 12-yr-old Japanese girl with pheochromocytoma due to a germline mutation in the VHL (Arg161Gln). The only complaint was loss of weight. Pyrexia, anemia, and increases in C-reactive protein (CRP) and ferritin were observed. Abdominal ultrasonography revealed a right adrenal gland tumor. Fractionated catecholamines and metanephrines in plasma and 24-h collected urine revealed elevated levels of norepinephrine and normetanephrine. Although hypertension and tachycardia were inapparent by an ordinary physical examination, paroxysmal mild hypertension and tachycardia were identified by a thorough examination after walking and abdominal compression. Paroxysmal hypertension and tachycardia were profound during operation. In conclusion, pheochromocytoma can be a consideration in the differential diagnosis of weight loss. Hypertension and tachycardia can be inapparent and paroxysmal in pediatric patients as well as in adults; thus, thorough assessment should be repeated.
