TY - JOUR. T1 - Ultrastructure of cerebellar hemangioblastoma - Some new observations on the stromal cells. AU - Shimura, T.. AU - Hirano, A.. AU - Llena, J. F.. PY - 1985/3. Y1 - 1985/3. N2 - Five cases of hemangioblastoma were studied by electron microscopy with particular attention to the stromal cells and their surrounding structures. Most of the stromal cells of the tumor had abundant clear cytoplasm containing rough endoplasmic reticulum, mitochondria, scattered fibrils, and large lipid inclusions. They were usually aggregated without intervening cells. In the perivascular areas, their sufaces facing the perivascular collagen were surrounded by basal lamina. Their apposed cell membranes had occasional adhesive devices. Occasional, long, apparently cylindrical processes of the stromal cell cytoplasm were observed in some cases. These processes contained intermediate filaments of undetermined nature and microtubules. In the border zone between the tumor and the surrounding brain, the stromal ...

Peritumoral hemangioblastoma cysts are usually composed of fibrous tissue without tumor cells. The authors describe the first case in which fluorescence with 5-aminolevulinic acid (5-ALA) was used to diagnose a hemangioblastoma tumor in a peritumoral cyst wall. A 27-year-old woman with a homogeneous, enhanced nodular lesion in the right hemisphere of the cerebellum underwent surgical treatment. After the nodular lesion was removed, the cyst region was observed with the aid of a semiconductor laser with a peak wavelength of 405 ± 1 nm, which was powered using a fiberoptic cable. The cyst region was visualized with strong fluorescence, which disappeared after tissue removal. The fluorescent cyst consisted of tumor cells. The authors conclude that fluorescence diagnosis performed using 5-ALA can inform the choice of removing hemangioblastoma cysts. ...

Hemangioblastoma are the rarest central nervous system tumours, accounting for less than 2% 1), and 7-12% of posterior fossa lesions in adult patients. Hemangioblastomas usually occur in adults, yet tumors may appear in VHL syndrome at much younger ages. Men and women are approximately at the same risk. Within the CNS, the most common site is the posterior fossa where the tumor often forms a solitary nodule in the wall of a glial-lined cyst 2) 3). In Von Hippel Lindau disease the incidence of development of hemangioblastoma in cerebellum is 44-72%, in brain stem is 10-25%, and in spinal cord is 13-50% 4). About one-fourth of hemangioblastomas occur in patients with Von Hippel-Lindau disease (VHL); the remainders are sporadic. Although extremely rare, solid hemangioblastomas outside the CNS have been reported, involving peripheral nerve 5) retroperitoneum 6) , soft tissue and bone 7) 8) 9) and visceral organs including the pancreas 10) , adrenals 11) 12) , liver 13) , and lung 14) 15).

A 39-year-old woman presented with neck and shoulder pain for 3 months. The MRI scan revealed a cystic-solid lesion located at C5 (figure 1, A-E). The patient received an operation and a small blood blister-like soft mass was detected. The tumor originated from proximal cervical nerve root and compressed the spinal medulla (figure 2, A-C). Pathologic diagnosis was hemangioblastoma (figure 2D). Postoperative gadolinium-enhanced MRI showed a gross total resection of the tumor (figure 1F). Spinal hemangioblastomas frequently originate from the medulla,1 and nerve root originated hemangioblastoma is scarce. Our case provides a direct-viewing description and pathologic confirmation of a new subset of classification for origin of spinal hemangioblastomas. ...

Hemangioblastoma (HB) in the supratentorial region of the brain is rare and only a few cases are reported on intraventricular HB. HB of the lateral ventricles is even rarer. We present a case of a 30-year-old man with generalized tonic clonic seizures. The brain computed tomography showed a 5.5 cm heterogeneous mass extending into both lateral ventricles with partial enhancement. Based on the size and imaging features, we present the fourth documented case of a large solitary intraventricular HB. Our approach to this unique case and some treatment complexities are also described.Considering the rarity of the case and the patients imaging features, the present study provides a better understanding of HB and recommends HB to be considered in the differential diagnosis of masses in the lateral ventricles. In addition, some preventable pitfalls in the treatment of such complex cases are described.

This report presents a case of fourth ventricle neurenteric cyst (NE cyst) mimicking hemangioblastoma, which developed in a 50-year-old woman. A tiny enhancing mural portion of the fourth ventricle in MRI suggested that the cyst was hemangioblastoma, but pathological evidence showed that the cyst was in fact NE cyst in the fourth ventricle. In order to make proper decision on to what extent of surgical resection should be done, considering every possibility in differential diagnosis might be helpful. This case reports an unusual pathology in 4th ventricle, considering the patients age, and demonstrates that a rarer disease may share radiological features of a common disease ...

Severe headache is characteristic for the cerebral subtype of the disease. Discomfort from spasm which is localized in the back of the head cannot be eliminated with spasm-prayer drugs and analgesics. Pain syndrome can be accompanied by nausea and frequent urge to vomit.. A common symptom of hemangioblastoma is optic nerve dysfunction. Vision problems force the patient to go to an ophthalmological clinic, which complicates the diagnosis of the disease. Also, the blurring of symptoms and the complexity of diagnosis is affected by vestibular ataxia, the signs of which are similar to inflammation of the inner ear with otitis media.. Cerebellar type features include cerebellar ataxia. Pathology consists of a complex of specific disorders of static and dynamic motor skills, disorders of coordination of movements.. When examined by a neurologist, megalography (a change in the usual handwriting to a more sweeping and large one), as well as dysmetria (non-ordered movements with a wide girth) can be ...

RhoA RhoB and RhoC GTPases are over 85% identical at the amino acid level with RhoA and RhoC differing at only one residue (43) across the initial two-thirds of their sequences. substitution of RhoA Val 43 with an Ile was found to significantly promote basal nucleotide exchange activity and enhance GTP-loading in cells. Substitution of Val 43 with an Ile in RhoB negatively affected nucleotide exchange in vitro. Substitution of LY317615 RhoC Ile 43 with a Val increased GEF-catalyzed exchange in vitro. In addition RhoC-I43V was more efficacious at generating ovarian tumor cell invasion through matrigrel than wild-type RhoC RhoC-I43T wild-type RhoA RhoA-V43I or RhoA-V43T GTPases. These results claim that a divergence between RhoA/B and RhoC at residue 43 influences basal and GEF-stimulated nucleotide exchange activity. cells (Stratagene) using glutathione-Sepharose 4B (Amersham Biosciences).

Purpose: Von Hippel-Lindau (VHL) disease is an autosomal dominant multisystemic disorder that gives rise to cystic and/or highly vascularized tumors. VHL is mutated or deleted and makes non-functional VHL protein leading to constitutive expression of hypoxia-inducible factor (HIF). This causes high levels of vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF) and erythropoietin (EPO) to be expressed in the tumor cell. Patients commonly present with retinal hemangioblastomas (RH) which can cause severe visual morbidity. VHL-null animal models do not fully recapitulate common features of human VHL disease and leave us with a limited understanding on targeted therapies for RH. Here we designed a murine xenograft model to evaluate new treatments for VHL disease-associated RH.. Methods: We used severe combined immunodeficiency (SCID) mice and intravitreally inoculated them with UMRC6 cells, a human VHL-null renal cell carcinoma cell line. The mice were either given an EPO ...

This study will examine whether the drug 17AAG (17-allylamino 17-demethoxygeldanamycin) can shrink kidney tumors in patients with Von Hippel-Lindau disease (VHL), a rare, inherited syndrome in which patients develop tumors in certain parts of the body. 17AAG contributes to the destruction of proteins in cells that may play in role in causing cancer and spurring tumor growth. The study will also look at the effect of 17AAG on other tumors patients may have that are caused by VHL, on the amount of blood vessels in the tumors, on the biologic activity of the tumor, and on cells circulating in the bloodstream, as well as the safety of the drug and its impact on the kidney tumor in patients whose tumor(s) is removed.. Patients 18 years of age and older with von Hippel-Lindau disease who have at least one kidney tumor large enough to pose a risk of metastasis (spread of cancer to other parts of the body) may be eligible for this study.

HBL is a histologically benign tumor that is associated with VHL disease in 20 % of cases but sporadic in 80 % of cases [1, 5]. Developmentally arrested HBL progenitor cells in the molecular layer of the cerebellum may progress to a tumor in patients with VHL, which is an autosomal dominant cancer predisposition syndrome caused by germline mutations in the VHL gene, a tumor suppressor gene localized at chromosome 3p25-26 that is responsible for tumors in different parts of the body. Patients with VHL syndrome are at risk for the development of new lesions over their lifetime, such as cysts in the pancreas, kidney, broad ligament, and epididymis, as well as clear cell renal cell carcinoma, pheochromocytoma, and/or retinal angiomas. These patients require a lifelong follow-up [6]. Given that a simple peripheral blood test can determine the presence of the VHL gene mutation, we recommend that this study is routinely performed for all patients with an HBL to guide follow-up.. The gene may also be ...

Purpose: Evaluation of phenotype and treatment outcome of retinal haemangioblastomas (RH) in von Hippel-Lindau (VHL) disease and correlation of these features with the genotype of VHL germline mutation carriers. Methods: Retrospective analysis of a longitudinal cohort of 21 VHL germline mutation carriers and RH. Clinical and genetic data were obtained to analyse the correlation of genotype with phenotype and treatment outcomes. Results: All patients were categorized in two genotypic categories: missense mutations (MM) and truncating mutations (TM). Mean follow-up duration was 16.3 years and did not differ significantly between mutation groups (p = 0.383). Missense mutations (MM) carriers (n = 6) developed more progression-related complications compared to TM carriers (n = 15) (p = 0.046). Vitreoretinal surgery was more often applied in MM carriers (p = 0.036). Moderate (visual acuity (VA)20/80 to 20/200) to severe (VA , 20/200) visual impairment was observed in 53.3% of the eyes of MM carriers ...

Regardless of age, every individual with vHL should undergo an annual history and physical examination, including blood pressure assessment and a comprehensive neurologic evaluation, assessing for deficits including evidence of visual disturbance or hearing impairment. Ideally, these visits would be conducted by a medical provider experienced in caring for individuals with vHL, who has access to a multidisciplinary team with expertise in managing vHL-associated tumors. At these visits, education should also be provided on the signs and symptoms that could raise concern.. Beginning from birth, ophthalmology exams should be performed annually, with particular attention to the retina to monitor for retinal hemangioblastomas. This is consistent with most current screening paradigms. These exams should be conducted by an ophthalmologist experienced in pediatric retinal evaluation. In addition, starting at 2 years of age, PHEO surveillance should commence with blood pressure checks at every medical ...

Patients affected with von Hippel-Lindau disease are at risk of developing multiple independent clear cell renal carcinomas. This study performed whole genome sequencing on 40 tumors from 6 VHL patients to compare somatic variation patterns within and between patients. Although tumors from the same patient showed many differences, within-patient patterns were discernible. Single-nucleotide substitution type rates were significantly different between patients and showed biases in trinucleotide mutation context. We also observed biases in chromosome copy number aberrations. These results show that genetic background and/or environment can influence the types of mutations that occur.. ...

Editor-Von Hippel-Lindau (VHL) disease is an autosomal dominant disorder characterised by a predisposition to develop a wide variety of benign tumours and malignant neoplasms, most frequently haemangioblastomas of the cerebellum and spinal cord, retinal haemangioblastomas, phaeochromocytomas, renal cysts, and clear cell carcinomas, pancreatic cysts and tumours, epididymal cystadenomas, and endolymphatic sac tumours.1-3 The combination of affected organs and the sequence of organ involvement vary considerably among families and even among individual patients in a family. Two types of families may, however, be distinguished according to the presence or absence of phaeochromocytoma.4 Central nervous system haemangioblastoma remains the main cause of death although renal cell carcinoma could represent a major problem in the future.5 Recent progress in research methods will render possible the identification of VHL gene mutations in virtually all families.6 Between 1995 and 1997, we have evaluated ...

A gene discovered by positional cloning has been identified as the von Hippel-Lindau (VHL) disease tumor suppressor gene. A restriction fragment encompassing the gene showed rearrangements in 28 of 221 VHL kindreds. Eighteen of these rearrangements were due to deletions in the candidate gene, including three large nonoverlapping deletions. Intragenic mutations were detected in cell lines derived from VHL patients and from sporadic renal cell carcinomas. The VHL gene is evolutionarily conserved and encodes two widely expressed transcripts of approximately 6 and 6.5 kilobases. The partial sequence of the inferred gene product shows no homology to other proteins, except for an acidic repeat domain found in the procyclic surface membrane glycoprotein of Trypanosoma brucei. ...

Objective. The Vhlh gene codes for the von-Hippel Lindau protein (VHL), a tumor suppressor that is a key player in the cellular response to oxygen sensing. In humans, a germline mutation in the VHL gene leads to the von Hippel-Lindau disease, a familial syndrome characterized by benign and malignant tumors of the kidney, central nervous system and the pancreas.. Research Design and Methods. We use Cre-Lox recombination to eliminate Vhlh in adult mouse pancreatic ß-cells. Morphology of mutant islets is assessed by immunofluorescence analysis. To determine the functional state of Vhlh−/− islets, insulin secretion is measured in vivo and in vitro, and quantitative PCR is used to identify changes in gene expression.. Results. Loss of VHL in ß-cells leads to a severe glucose intolerant phenotype in adult animals. Although VHL is not required for ß-cell specification and development, it is critical for ß-cell function. Insulin production is normal in ß-cells lacking VHL, however, insulin ...
