Case: M, 35Y0M, Hungarian

DiseaseAssertion: VHL

FamilyInfo: Index patient presented with cerebellar hemangioblastoma, renal cysts, pancreatic cyst and bilateral renal cell carcinomas. Family members were not available for clinical and genetic screening except a brother whose screening revealed no abnormality.

CasePresentingHPOs: HP:0006880; HP:0005562; HP:0005584; HP:0001737 (Cerebellar hemangioblastoma, Multiple renal cysts, Renal cell carcinoma, Pancreatic cysts)

CaseHPOFreeText: Patient was operated for cerebellar hemangioblastoma at the age of 33 years. Preoperative clinical screening also showed renal cysts. Two years later, a pancreatic cyst and bilateral renal cell carcinomas were found and the patients underwent bilateral nephrectomy with subsequent chronic hemodialysis. Diagnosed with VHL Type 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.
