ABSTRACT
Von Hippel-Lindau (VHL) disease is an autosomal dominant inherited condition with a predisposition to the development of a variety of tumors including pheochromocytomas. A number of cancer surveillance protocols for patients with VHL have been developed, all of which are based on expert opinion. We report a case of two brothers with a strong family history of VHL type 2 due to a pathogenic germline VHL variant, specifically, a surface missense substitution, with a rapidly progressive clinical course that both presented with a large adrenal mass. Both brothers presented with large pheochromocytomas, the earliest presentation being at age 7, despite routine screening. The rapid progression and early presentation of these patients raises an important discussion around the commonly used surveillance protocols for pheochromocytoma in pediatric patients with VHL and missense mutations. We conclude that a more accelerated surveillance protocol may be adequate for VHL families with a high pheochromocytoma risk.
