DiseaseAssertion: Assumed VHL

FamilyInfo: The patient’s aunt presented with Hodgkin’s lymphoma at 38Y and was deceased at 40Y. The patient’s father presented with liver cancer at 72Y and was deceased at 74Y. Additionally, the patient’s deceased grandfather had an unspecified cancer. The patient’s son presented with unilateral pheochromocytoma at 13Y. The patient’s daughter presented with pheochromocytoma at 12Y, and bilateral retinal hemangioblastoma, right adrenal pheochromocytoma, and islet cell neuroendocrine carcinoma of the pancreas with nodal metastasis at 20Y, and was found to carry the mutation the patient carried.

Case: M, 22Y0M, Caucasian

DiseaseAssertion: VHL

FamilyInfo: Positive family history.

CohortInfo: Case series of 14 patients with definite or presumed von Hippel-Lindau disease and retinal vascular proliferation.

CasePresentingHPOs: HP:0002011, HP:0001732, HP:0007850, HP:0012210, HP:0009711 (Morphological central nervous system abnormality, abnormality of the pancreas, retinal vascular proliferation, abnormal renal morphology, retinal capillary hemangioma)

CaseHPOFreeText: At age 12, his left eye had a large juxtapapillary vascular complex extending from the nerve along the superior arcade that was associated with dense fibrovascular tissue. During the next 29 months, this fibrovascular complex enlarged, extending into the center of the macula and causing a decrease in visual acuity to 20/80. The patient underwent pars plana vitrectomy and membrane peel. When the patient was reexamined 7 years after his surgery, there was no recurrence of the lesion. In the patient's contralateral right eye, 3 typical peripheral RCHs were observed during this 7-year follow-up. At age 14 years, he was also noted to have a small patch of superficial retinal vessels in the inferior retinal quadrant near the equator of the right eye that resembled an arteriovenous anastomosis.
