Understanding of molecular mechanisms of tumor growth has an increasing impact on the development of diagnostics and targeted therapy of human neoplasia. In this review, we summarize the current knowledge on molecular mechanisms and their clinical implications in von Hippel-Lindau (VHL) disease. This autosomal dominant tumor syndrome usually manifests in young adulthood and predisposes affected patients to the development of benign and malignant tumors of different organ systems mainly including the nervous system and internal organs.

Spinal cord tumors are a challenge for patients and neurosurgeons because of the high risk of neurologic deficits from the disease process and surgical interventions. Spinal cord tumors are uncommon, and approximately 2%-3% of primary intra-axial tumors of the central nervous system occur in the spinal cord. Primary intra-axial tumors are usually derived from neuroepithelial tissue, especially glial cells. Read More

Introduction: Hemangioblastomas are rare, histologically benign, highly vascularized tumors of the brain, the spinal cord, and the retina, occurring sporadically or associated with the autosomal dominant inherited von Hippel-Lindau (VHL) disease. Children or adults with VHL disease have one of > 300 known germline mutations of the VHL gene located on chromosome 3. They are prone to develop hemangioblastomas, extremely rarely starting at age 6, rarely at age 12-18, and, typically and almost all, as adults. Read More

Introduction: Central nervous system hemangioblastoma is a benign tumor associated with or without von Hippel-Lindau (VHL) disease which is an autosomal dominant hereditary disease that results from a germline mutation in the VHL gene. A main axis of signaling pathways in central nervous system hemangioblastoma is VHL-HIF signaling pathway. Here, we propose an alternative VHL-JAK-STAT signaling pathway in hemangioblastoma and discuss the role. Read More

DOTA-D-Phe-Tyr-octreotide labeled with Ga (Ga-DOTATOC) is the commonly used PET tracer for imaging meningioma because of its high affinity to somatostatin receptor subtype 2 (SSTR2) and an established imaging modality for planning radiation and radionuclide therapy. However, SSTR2 is not an exclusive marker for meningioma, and not all meningiomas express high levels of SSTR2. The SSTR2 expression has been reported in other intracranial tumors, for example, glioma, pituitary adenoma, medullablastoma, primitive neuroectodermal tumors, and hemangioblastoma leading to a significant risk of misinterpretation of PET/CT findings.

Retinal hemangioblastoma (also referred to as retinal capillary hemangioma) is a benign lesion originating from the endothelial and glial components of the neurosensory retina and optic nerve head. Historically known as a manifestation of the von Hippel-Lindau (VHL) disease, it can be seen as an isolated finding or in association with some rare ocular conditions. In addition to characteristic ophthalmoscopic features, results of numerous ancillary tests including angiography, ultrasound, optical coherence tomography, and genetic tests may support the diagnosis and differentiate it from similar conditions.

Even in the era of intravitreal injection therapy (intravitreal operative injection of medication, IVOM) for the treatment of macular and retinal diseases, such as age-related macular degeneration (AMD), proliferative diabetic retinopathy (DR) and diabetic macular edema (DME) as well as proliferative stages and/or macular edema due to retinal vein occlusion (RVO), conventional retinal laser treatment is still of importance. It can be focally performed on an on-label basis for DME and macular edema due to branch RVO (BRVO) and its use as panretinal treatment for proliferative stages in retinal diseases as well as for the treatment of retinal holes is undisputed.
