Case: M, 20Y0M, Brazilian (Latino/Admixed American)

DiseaseAssertion: VHL

FamilyInfo: Also belonging to family 1, patients 1 and 3 had VHL diagnoses and phenotypes. Their relation is not clear.

CasePresentingHPOs: HP:0006748, HP:0002666; HP:0030405; HP:0010797 (adrenal pheochromocytoma, pheochromocytoma, pancreatic endocrine tumor, hemangioblastoma)

CaseHPOFreeText: The patient developed PPGL at 4Y of age, and a PNET at 20Y: the 4-year-old boy with VHL disease with a history of sudoresis, headache, and abdominal pain. During evaluation, he was diagnosed with hypertension. An abdominal CT scan revealed a 5-cm heterogenous mass in the right adrenal and normal left adrenal glands. This patient underwent a right nodulectomy to preserve normal adrenal tissue. Anatomopathological diagnosis confirmed PHEO. 3 years later was a bilateral recurrence (4-cm right and 1.5-cm left nodules). The patient underwent a right-side adrenalectomy and a left-side nodulectomy. He remained without hormone replacement. After 13 years from the second surgery, the boy presented with a left-side recurrence (1.3-cm nodule) and elevated plasmatic normetanephrine levels; he underwent left-side adrenalectomy.
