Detection of a germline mutation and somatic homozygous loss of the von Hippel-Lindau tumor-suppressor gene in a family with a de novo mutation
1996
von Hippel-Lindau (VHL) disease is a pleiotropic disorder featuring a variety of malignant and benign tumors of the eye, central nervous system, kidney, and adrenal gland. Recently the VHL gene has been identified in the chromosomal region 3p25-26. Prognosis and successful management of VHL patients and their descendants depend on unambiguous diagnosis. Due to recurrent hemangioblastomas, a29-year-old patient without familial history of VHL disease was diagnosed to be at risk for the disease. Histopathological examination of a small renal mass identified a clear cell tumor with a G1 grading. Genetic characterization of the germline and of the renal tumor was performed.

Novel clinical insights into spinal hemangioblastoma in adults: a systematic review
2021
ABSTRACT Background Hemangioblastomas are well vascularized, benign CNS tumors and the third most common primary spinal cord tumor after astrocytoma/ependymoma, occurring sporadically or as a part of an autosomal dominant von Hippel-Lindau disease in which tumors are often multiple and prone to relapse. Spinal hemangioblastomas are commonly located in the cervical cord and associated with a syrinx formation. Due to location and growth trends, they may cause significant neurological deficit, impairing patient quality of life. We conducted a systematic review to understand better clinical insights of spinal hemangioblastoma in adults and compare spinal hemangioblastoma versus posterior crania…
