CaseHPOFreeText: Presented at age 39 with bilateral renal tumors (2 right side, 3 left side). Pathological evaluation revealed clear cell type renal cell carcinoma (fig. 1, B). After 2 years multiple pancreatic cysts were noted. Two years later 6 bilateral renal cell carcinoma lesions developed. Five years later at age 48 years mental confusion developed and brain MRI showed a cerebellar lesion; histological evaluation revealed cerebellar hemangioblastoma.

Case: M, 45Y0M, Ethnicity Unknown

DiseaseAssertion: VHL

FamilyInfo: Both of the patient’s brothers (Patient II-3 and II-4), the patient’s sister (II-5), and the patient’s nephew (III-3) were clinically diagnosed with VHL disease. Patient II-4 presented with RCCC at age 53, and carried the mutation NM_000551.3:c.269A>T. Patient III-3 presented with CH and carried the same mutation. The patient’s other brother (Patient II‐3) and sister (Patient II‐5) were deceased and had an undetermined mutation. Patient II-3 died of an advanced RCCC, and Patient II‐5 died of a ruptured CH. The patient’s parents (Patient I-1 and I-2) were also deceased from other causes. The patient’s grand-nephew (Patient IV‐1) was healthy and did not carry the mutation.

CasePresentingHPOs: HP:0006770; HP:0006880 (Renal clear cell carcinoma, cerebellar hemangioblastoma)

CaseHPOFreeText: The 45Y male patient was diagnosed with left RCCC at 33Y, but had no symptoms. The patient presented with complaints of headache and dizziness at age 41Y, and was diagnosed with a right cerebellar hemangioblastoma. In the most recent follow‐up, his symptoms had disappeared, and radiological imaging of the brain and abdomen revealed no recurrence.
