PatientID: IP (Proband)

KindredID: E

Case: M, 21Y0M, Hungarian

DiseaseAssertion: VHL

FamilyInfo: Index patient was a 21-year-old man who had bilateral renal masses and renal cysts. Family history indicated a high suspicion for VHL disease, as his mother was operated for renal cell carcinoma, his uncle had spinal cord tumor, and his grandmother underwent operation for renal cell carcinoma. However, detailed clinical evaluation could not be performed in family members.

CasePresentingHPOs: HP:0005584; HP:0005562 (Renal cell carcinoma, Multiple renal cysts)

CaseHPOFreeText: Presented with bilateral highly vascularized renal masses and a large number of renal cysts. Diagnosed with VHL Type 1. Renal masses are noted as renal cell carcinoma in Table 1.

CasePresentingHPOs: HP:0006880; HP:0002894; HP:0005584 (Cerebellar Hemangioblastoma; neoplasm of the pancreas; renal cell carcinoma)

CaseHPOFreeText: At 35-year old, the female patient was diagnosed with VHL due to clinical presentation of pancreatic serous cystic neoplasm and renal cell carcinoma, and cerebellar hemangioblastomas that were surgically removed at age 21. The patient had underwent total pancreatectomy and right nephrectomy for pancreatic serous cystic neoplasm (SCN) and renal cell carcinoma (RCC), respectively. 4 years later, tumors in the liver were detected by CT scan and radiographically diagnosed as metasta-ses of the pancreatic SCN or RCC. Again, morphology and immunohistochemical findings of the resected tumors again were similar to the primary pancreatic SCN, thus diagnosed as multiple metachronous liver metastases of pancreatic SCN. As of 47Y, the patient has remained disease-free without any recurrence after the third operation.

FamilyInfo: The proband (patient 155) has a sister (patient 156) and a nephew (son of sister, patient 157) that were both genetically confirmed with the mutation. The sister presented with a CNS hemangioblastoma at 21 and multiple pancreatic cysts/tumors at 27, and the nephew was asymptomatic at the time of analysis.
