Resumen:
von Hippel Lindau disease(VHL) is an inherited syndrome caused
by mutations of the VHL gene. It predisposes to the development of
hemangioblastomas, renal or pancreatic cysts or tumors, endolymphatic
sac tumors or pheochromocytomas. We aimed to evaluate the
presentation and outcome of VHL in patients under 20 years of age.
We studied 23 patients (16 males) belonging to 15 families with VHL
disease confirmed by molecular biology. Mean age at presentation:12
years (range 4-20). The initial manifestation of VHL was pheochromocytoma
in 20/23 patients (11/20 bilateral). The remaining patients
presented endolymphatic sac tumor (1) and CNS angioma (2). Median
disease-free interval 8 years (2-42). 11/22 had no recurrence (follow
up 6-42 years, median 14). One patient died after six years (cerebral
hemorrhage). 11/22 later developed other tumors (between 2 to
31 years, median 16). 4/11 presented CNS or retina hemangiomas,
4/11 pheochromocytoma, 3/11 hemangioblastoma, kidney or pancreas
tumors or cysts simultaneously. Members of the same family
presented diferent tumors. We emphasize the need for the search for
VHL disease in children mainly with pheochromocytoma, as well as
whole life surveillance, since comorbid pathology can show up after
a long disease-free period.
