FamilyInfo: Mother was found with the same VHL germline variant. His mother presented with bilateral pheochromocytoma.

CasePresentingHPOs: HP:0002315; HP:0000651; HP:0002666; HP:0009711; HP:0000822 (Headache, Diplopia, Pheochromocytoma, Retinal capillary hemangioma, Hypertension)

CaseHPOFreeText: Admitted with complaints of headache and diplopia. MRI indicated the presence of multiple lesions in perivascular areas neighboring both adrenal glands. An iodine 123 metaiodobenzylguanidine (MIBG) scan revealed multiple focal areas of increased uptake near the adrenal glands. The diagnosis of bilateral pheochromocytoma was confirmed histologically and immunohistochemically. The patient remained asymptomatic with no laboratory or radiologic abnormalities for six years of follow-up. At the age of 16, the patient was referred to our clinic with a visual defect in the left eye. Ophthalmologic examination led to the diagnosis of bilateral retinal hemangiomas, and he underwent laser photocoagulation.

Case: M, 16Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The family with PCCs includes 56 members of 4 generations, and is from Gansu Province. Among them, 7 extended over 3 generations were diagnosed as PCCs. One died before admission and another died due to a cardiovascular incident. Five were initially evaluated; evaluation included medical history, physical examination, abdominal ultrasonography, CT or MRI and laboratory tests. All 5 probands of this family underwent surgical resection. The tumors were benign under pathological examinations. There were no recurrence and malignant transformation over the period of up to 23-year follow-up. Twenty members, including 5 live patients and 15 direct relatives, accepted genetic examination.

CasePresentingHPOs: HP:0002666 (Pheochromocytoma)

CaseHPOFreeText: Bilateral PCC diagnosed at 16Y and did not have any other clinical presentations. Stated as having VHL type IIC.
