Case: F, Age Unknown, Ethnicity Unknown
DiseaseAssertion: VHL
FamilyInfo: Her fourth oldest sister had bilateral retinal angiomas, metastatic islet cell cancer, liver lesions, pancreatic endocrine tumours, and cerebellar hemangioblastoma. Her second oldest sister had two hypervascular pancreatic head tumours, a complex left renal cyst, and enlarged bilateral ovarian cysts. Her third oldest sister had a pancreatic head tumour and bilateral renal cysts. The oldest sister did not carry the mutation or have any abnormal presentations. The patient's mother was found to harbor the mutation and had retinal angiomas, bilateral adrenal pheochromocytoma, and pancreatic cysts. The patient's maternal grandmother was suspected to have VHL as she developed progressive blindness at age 32 and was completely blind by age 36. She died at age 68 due to an acute hemorrhage into and around a vascular tumour. The patient's maternal aunt died suddenly at age 51 due to a cerebellar hemangioblastoma. One of the aunt's children died at age 25 due to a cerebellar hemangioblastoma and another had bilateral retinal angiomas and multiple pancreatic cysts. Refer to Figure 1 for pedigree.
CasePresentingHPOs: HP:0009711, HP:0030405, HP:0002896 (retinal capillary hemangioma, pancreatic endocrine tumour, neoplasm of the liver)
CaseHPOFreeText: Presented with bilateral retinal angiomas. Abdominal CT revealed a pancreatic head mass and in surgery multiple 1 to 2 mm bilobar liver lesions were revealed. These were histologically confirmed to be metastatic islet cell disease.The primary pancreatic tumor that involved the superior mesenteric artery also demonstrated an islet cell neoplasm.
