[Right adrenal recurrence of pheochromocytoma discovered 24 years after ablation of two ectopic pheochromocytomas].

The classical localisation of chromaffin cell tumours is intra-adrenal. Ectopic or multiple tumours are not rare and are commonly observed in children. The authors report a case of ectopic pheochromocytoma with a double localisation in a 14 year old child (renal pedicle and right retropleural space), in which surgical ablation resulted in an immediate and sustained correction of the hypertension. Hypertension recurred 24 years later and a classical right adrenal pheochromocytoma was demonstrated by methyl-iodo-benzylguanidine (M.I.B.G.) scintigraphy and abdominal CT scan. Right adrenalectomy resulted in normalisation of the hypertension once again without antihypertensive therapy with a follow-up of three years. Regular follow-up is necessary after ablation of a pheochromocytoma, especially in children, even in the absence of a phacomatosis or multiple endocrine neoplastic syndromes.
