Tumors associated with Von Hippel-Lindau disease

a) 50–70% of Von Hippel-Lindau disease patients have bilateral and multiple renal cysts

b) rarely cause profound renal impairment

c) chronic renal failure or renal hypertension not as common as with polycystic kidney disease

a) benign lesions that arise from the epididymal duct

b) found in 10–60% of male VHL patients

c) typically appear in the teenage years

d) may cause infertility if bilateral

e) may be multiple

Broad ligament cystadenomas

a) arise from the embryonic mesonephric duct

b) true incidence unknown

c) rarely reported and usually not recognized in women with VHL

Pancreatic neuroendocrine tumors and cysts

a) 35 to 70% of patients with VHL develop an endocrine tumor or cyst

b) pancreatic cysts are generally asymptomatic and often multiple

c) pancreatic neuroendocrine tumors are usually non-functional and 8% of them are malignant

d) differential diagnosis: pancreatic islet cell tumors, MEN2

Sinonasal renal cell-like adenocarcinoma is an emerging tumor associated with VHL syndrome and it is hoped that future studies shed light on the underlying biology of this unique tumor ¹⁾.
