Abstract
Tumor-to-tumor metastasis in the central nerve system is uncommon in our routine practice. Most reports include metastatic breast cancer into meningioma. Here we report a metastatic clear cell renal cell carcinoma (ccRCC) into a cerebellar hemangioblastoma in a patient with von Hippel-Lindau (VHL) disease. Imaging cannot distinguish metastatic ccRCC from primary cerebellar hemangioblastoma. Immuno-molecular studies are proven to be diagnostic. We also reviewed previously documented tumor-to-tumor metastasis of ccRCC to cerebellar hemangioblastoma in VHL disease. Lastly, we discussed potential mechanisms involved in the metastasis of ccRCC to hemangioblastoma in the cerebellum in patients with VHL.

Abstract
Collision tumors are rarely reported in patients with von Hippel-Lindau (VHL) disease, even though VHL patients often present with multi-organ tumor syndromes, like hemangioblastoma and renal cell carcinoma (RCC). Hemangioblastoma is rarely located in a supratentorial location, and intracranial lateral ventricular is also not a common site of metastasis for RCC. It is extremely rare for the two tumors to collide in the supratentorial area. We report a 64-year-old man with a history of clear cell RCC who presented with a sudden headache. The brain magnetic resonance imaging revealed that there was a cystic-solid mass in the intracranial lateral ventricular trigone. Histopathologically, the tumor consisted of two distinct components, most of which showed the typical morphology of hemangioblastoma. However, there were a few acinar structures composed of clear cells scattered in hemangioblastoma, and these acinar structures were subsequently confirmed as clear cell RCC. The genetic testing confirmed that the patient had VHL disease with de novo somatic mutation. Based on our case report, we systematically reviewed the characteristics of collision tumor composed of hemangioblastoma and metastatic RCC in VHL patients. The special growth site of our case is the first report of this kind of collision tumor, and can also help enrich our understanding of VHL disease and collision tumor.

Abstract
CASE A 73-year-old man with a medical history significant for renal cell carcinoma (RCC) presented with widespread osseous metastases and imaging suspicious for RCC metastasizing to a lipoma interdigitated within the right vastus lateralis. The patient's pathological fractures were surgically addressed, and the lipoma excised. Final histology revealed a thigh lipoma involved by metastatic RCC without direct extension. CONCLUSION Tumor-to-tumor metastasis is a rare occurrence, with RCC typically being the most common "recipient" tumor. This is the first case to the best of our knowledge of RCC metastasizing to a lipoma, highlighting a rare phenomena in a patient with metastatic disease.

Abstract
von Hippel–Lindau (VHL) disease is characterized by neoplastic and cystic lesions, such as central nervous system (CNS) hemangioblastoma and clear cell renal cell carcinoma (RCC), arising in multiple organs. Here, we report a case of an RCC that metastasized to a spinal hemangioblastoma in a patient diagnosed with VHL disease. This is a unique case study because visceral neoplasms rarely metastasize to the CNS. The patient had undergone posterior fossa surgery for the removal of hemangioblastomas in the right cerebellar hemisphere as a child. He was diagnosed with RCC at the age of 20 years, and he underwent partial nephrectomy at the age of 35 years. The patient underwent surgical removal of a spinal tumor from Th8, which was also diagnosed as a hemangioblastoma at the age of 40. However, the residual spinal tumor rapidly regrew within 1.5 years. A second surgery was performed due to progressive leg motor weakness. The resected tumor from the second surgery had two distinct components between the tumor center and the margin. Immunohistochemistry of CD10, PAX 8, and inhibin A demonstrated the predominant region of the tumor was RCC. Pathological findings confirmed tumor-to-tumor metastasis of the RCC migrating into residual spinal hemangioblastoma. It can be challenging to distinguish hemangioblastoma from RCC in neuroimaging. We suggest that tumor-to-tumor metastasis should be considered as a differential diagnosis if benign tumors grow rapidly, even if the pathological diagnosis does not initially confirm malignancy. The biological mechanisms of RCC migrating into residual hemangioblastoma are discussed.

Abstract
BACKGROUND The incidence of 2 distinct tumor types occupying the same anatomic location is rarely observed and may be accounted for by 2 separate mechanisms: tumor-to-tumor metastasis and collision tumors, where 2 adjacent tumors invade one another. These rare phenomena arise from distinct mechanisms, which may affect their preoperative recognition, surgical approach, and postoperative care. We review 2 cases, highlighting their identification and perioperative management. CASE DESCRIPTIONS In case 1, a 71-year-old patient with a history of sphenoid wing meningioma presented with headache, nausea, and vomiting and was found to have a mass with meningioma and glioblastoma (GBM) characteristics. In case 2, a 61-year-old man with worsening dysmetria in the setting of unintentional weight loss presented with multiple masses in the pelvis, abdomen, lung, and brain. The brain masses were classified as meningioma with intratumoral metastatic adenocarcinoma foci. CONCLUSIONS Preoperative recognition of collision tumor and tumor-to-tumor metastasis is imperative for surgical planning, including selecting regions for tissue biopsy and goals of care. Meticulous evaluation of history and imaging and thorough pathologic analysis allow for effective diagnosis and optimal patient outcomes.

Abstract
BACKGROUND Posterior cranial fossa (PCF) hemangioblastomas are benign, highly vascularized, and well-differentiated tumors with well-described histopathologic features. Although relatively rare, this tumor is the most prevalent primary tumor of the cerebellum in adults. OBJECTIVE Because the demographics of patients with such a tumor (as well as the clinical, morphologic, pathologic, surgical features, and outcomes) are not fully understood, we systematized characteristic patient and tumor features. METHODS We undertook a systematic review of the English-language literature in PubMed for PCF hemangioblastomas in adults published in the past 31 years. We analyzed geographic distribution and year of publication of articles; demographic data of patients; presenting symptoms and clinical signs; tumor location and morphology; histopathologic features, extent of tumor resection, perioperative blood loss, and postoperative complications; length of hospital stay; and outcomes. RESULTS We reviewed 207 articles describing 1759 infratentorial hemangioblastomas in a cohort of 1515 adult patients. We found female predominance in patients with Von Hippel-Lindau disease (VHLD) compared with male predominance in the general patient group. Symptoms of intracranial hypertension were more common in the VHLD group compared with the general group of patients. The cerebellar location was more common in the VHLD group and solid (parenchymatous) tumor was the most common type. Most patients underwent total resection but rate of resection did not differ between the general and VHLD groups. Most patients had a favorable outcome. CONCLUSIONS The literature of adult PCF hemangioblastomas is limited and general surgical experience with such tumors is scarce because of their rarity. Rates of postoperative complications and mortality remain higher than expected. However, prognosis and surgical outcomes are generally favorable. Nevertheless, surgery of adult PCF hemangioblastomas is a demanding and challenging task.

Abstract
Spinal nerve root metastasis of renal cell carcinoma is a rare occurrence. In addition to treatment of the primary lesion, surgical resection of the nerve root metastasis, occasionally with sacrifice of the involved nerve, is the accepted standard of treatment. Resection often resolves presenting motor and pain symptoms due to relief of neural compression. We describe two patients with nerve root metastasis of renal cell carcinoma and their management. While locally advanced and metastatic renal cell carcinoma has been shown to be chemo- and radio-resistant, immunotherapy is a promising treatment. Given the high prevalence of systemic disease in patients with intradural metastases, systemic (and possibly intracranial) imaging can be used to identify other potential areas of disease.

Abstract
Patients with von Hippel-Lindau disease carry a germline mutation of the Von Hippel-Lindau (VHL) tumor-suppressor gene. We discuss the molecular consequences of loss of VHL gene function and their impact on the nervous system. Dysfunction of the VHL protein causes accumulation and activation of hypoxia inducible factor (HIF) which can be demonstrated in earliest stages of tumorigenesis and is followed by expression of VEGF, erythropoietin, nitric oxide synthase and glucose transporter 1 in VHL-deficient tumor cells. HIF-independent functions of VHL, epigenetic inactivation of VHL, pVHL proteostasis, and links between loss of VHL function and developmental arrest are also described. A most intriguing feature in VHL disease is the occurrence of primary hemangioblastic tumors in the nervous system, the origin of which has not yet been entirely clarified, and current hypotheses are discussed. Endolymphatic sac tumors may extend into the brain, but originally arise from proliferation of endolymphatic duct/sac epithelium; the exact nature of the proliferating epithelial cell, however, also has remained unclear, as well as the question why tumors almost consistently develop in the intraosseous portion of the endolymphatic sac/duct only. The epitheloid clear cell morphology of both advanced hemangioblastoma and renal clear cell carcinoma can make the differential diagnosis challenging, recent developments in immunohistochemical differentiation are discussed. Finally, metastasis to brain may not only be caused by renal carcinoma, but may derive from VHL disease-associated pheochromocytoma/paraganglioma, or pancreatic neuroendocrine tumor.

Abstract
Hemangioblastoma (HBL) accounts for up to 2.5% of all intracranial tumors. It may occur as a sporadic entity or as a part of Von Hippel-Lindau syndrome. Patients with Von Hippel-Lindau syndrome are also at an increased risk of developing clear cell renal cell carcinoma (CCRCC). The distinction of HBL from CCRCC metastatic to the central nervous system (CNS) or from other histologic mimics can be challenging at times when based solely on hematoxylin and eosin-stained sections. In the present study we evaluated the potential use of the immunohistochemical evaluation of brachyury protein in the differential diagnosis of these lesions. Archival tissues from 22 HBLs, 16 primary CCRCCs, 8 CCRCCs metastatic to the CNS, and 4 angiomatous and 4 clear cell meningiomas were retrieved from our surgical pathology files and submitted to the immunohistochemical procedures against brachyury. Cases showing nuclear and/or cytoplasmic staining were considered to be positive for brachyury. Positive cytoplasmic staining was evidenced in the stromal cells of 20 of the 22 HBLs. In most cases, >50% of the neoplastic cells were labeled, with strong or moderate intensity of staining. No nuclear or cytoplasmic staining for brachyury was observed in any of the primary renal or metastatic CCRCCs, nor in either of the meningioma types. Thus, brachyury cytoplasmic staining was demonstrated to be highly specific for HBL (specificity, 100%) and represented a sensible (sensitivity, 91%) method, with high positive (100%) and negative (89%) predictive values and high diagnostic accuracy (95%) in the differential diagnosis between HBL and CCRCC metastatic to the CNS or meningioma. On the basis of our findings we propose the use of brachyury as an additional helpful immunohistochemical marker to resolve the differential diagnosis of HBL toward histologic mimics.

Abstract
The diagnosis of metastatic clear cell renal cell carcinoma may be difficult in some cases, particularly in the small image-guided biopsies that are becoming more common. As targeted therapies for renal cell carcinoma are now standard treatment, the recognition and diagnosis of renal cell carcinoma has become even more critical. Many adjunctive immunohistochemical markers of renal epithelial lineage such as CD10 and RCCma have been proposed as aids in the diagnosis of metastatic renal cell carcinoma, but low specificities often limit their utility. More recently described markers (PAX-2, PAX-8, human kidney injury molecule-1, hepatocyte nuclear factor-1-β, and carbonic anhydrase-IX) offer the potential for greater sensitivity and specificity in this diagnostic setting; however, knowledge of their expected staining in other neoplasms and tissues is critical for appropriate use. In this review, we discuss the most widely used immunohistochemical markers of renal lineage with an emphasis on their sensitivity and specificity for metastatic clear cell renal cell carcinoma. Subsequently, we present a variety of organ-specific differential diagnostic scenarios in which metastatic clear cell renal cell carcinoma might be considered and we propose immunopanels for use in each situation.

Abstract
Tumor to tumor metastasis is a rare, but well recognized entity, most commonly involving a carcinoma metastasis to a benign or low grade mesenchymal tumor. A case of breast carcinoma metastasis in a recurrent myxoid liposarcoma is presented in this study. A 52-year-old female patient with a history of breast carcinoma (70% invasive lobular carcinoma and 30% invasive ductal carcinoma) presented with a mass in the right lumbar region. The excised mass was diagnosed as myxoid liposarcoma. The tumor recurred twice and was reexcised. Microscopic examination of the second recurrence revealed multiple foci of breast carcinoma metastases in myxoid liposarcoma. Immunohistochemical study showed staining for CK19, GCDFP-15, estrogen and progesterone in metastases. Both breast carcinoma metastasis and myxoid liposarcoma were immunoreactive for E-cadherin and beta-catenin. To our knowledge, this is the first reported case of breast carcinoma metastasis in myxoid liposarcoma, and the first occurrence of metastasis in a liposarcoma.

Abstract
Immunohistochemistry (IHC) has become an important adjunct tool in diagnostic neuro-oncology practice enabling immunophenotypic characterization of tumor cells. There have been several recent publications regarding new IHC markers that are useful for diagnosis of brain tumors. To introduce the latest advances in IHC in this field, we review the features of novel IHC marker antibodies applicable to selected nonglial tumors in the nervous system, based on recently published reports and our own experiences. We discuss (1) aquaporin-1 and alpha-inhibin for hemangioblastoma, (2) beta-catenin for craniopharyngioma, (3) brachyury for chordoma, and (4) INI-1 for hereditary schwannomas. All the markers presented here are used primarily for supporting or confirming the histologic diagnosis, with the exception of (4), which may be of help in identification of inherited forms in schwannomas. As with other surgical pathology practices, the judicious use of a panel of IHC antibodies selected on the basis of the histologic findings is important for an accurate diagnosis of brain tumors. Of note is that IHC results should be always interpreted in the histopathologic context.

Abstract
Metastatic disease in the intradural compartment of the spine is a rare manifestation of cancer. We report the case of an 82-year-old patient with an intradural, extramedullary metastasis of renal cell carcinoma in the cervical spine. A literature search for intradural spinal metastases of renal cell carcinoma yielded a total of 26 further cases. 18 patients had sporadic renal cell carcinoma, and 9 patients had von Hippel-Lindau disease (VHL) in which the metastases of the renal cell carcinoma were embedded within spinal haemangioblastomas. Patients presented with paresis, back pain, altered sensation or, less frequently, bladder dysfunction. Intradural spinal metastases were diagnosed at an earlier age in VHL patients than in sporadic cases (mean 43 +/- 5 years vs. 60 +/- 14.5 years). The metastasis was surgically removed in 81% of patients. Pain improved in all patients, paresis in 90%, hypaesthesia in 38% and bladder dysfunction in 50%. Death occurred as a result of systemic cancer progression. 93% of patients in the sporadic renal cell cancer group died within 1.5 years, whereas two thirds of the VHL patients were alive after 2 years.

Abstract
Distinguishing hemangioblastomas from metastatic clear-cell renal cell carcinomas (CCRCCs) in the brain is a diagnostic challenge owing to similar clinical and morphologic presentations. Inhibin-alpha and aquaporin1 were shown as positive markers of hemangioblastoma, but are not totally reliable distinguishing hemangioblastoma from metastatic CCRCC. This study shows that the diagnosis can be achieved using a combination of markers. To identify the panel of markers useful for this differential, 67 hemangioblastomas and 34 metastatic CCRCCs were analyzed using a panel of antibodies including aquaporin1, inhibin-alpha, D2-40, cytokeratin AE1/AE3, epithelial membrane antigen, and CD10. The study confirms the usefulness of aquaporin1 (97% sensitivity, 83% specificity) and inhibin-alpha (88% sensitivity, 79% specificity) as positive markers of hemangioblastoma and shows that aquaporin1 is a superior positive marker versus inhibin-alpha for the differential. Positivity of tumor cells with cytokeratin AE1/AE3 is the signature of a metastatic CCRCC (100% specificity, 88% sensitivity) and CD10 expression as well (100% specificity, 79% sensitivity). The combined use of aquaporin1 and AE1/AE3 yields a high degree of sensitivity and specificity to differentiate between hemangioblastoma and metastatic CCRCC. All tumors but one aquaporin1 positive and cytokeratin AE1/AE3 negative (65/66) correspond to hemangioblastomas (97% sensitivity, 97% specificity, 98.5% diagnostic positive predictive value). Tumors with the opposite profile, aquaporin1 negative, and cytokeratin AE1/AE3 positive, (25/25), correspond to metastatic CCRCC (74% sensitivity, 100% specificity, 100% diagnostic positive predictive value). In summary, aquaporin1 is the most sensitive positive marker of hemangioblastoma. Despite its moderate specificity, when used in combination with epithelial marker AE1/AE3, it allowed to reliably distinguish hemangioblastoma from metastatic CCRCC.

Abstract
Haemangioblastomas are rare neoplasms of uncertain histogenesis. They represent 1.5-2.5% of intracranial tumours. While the cerebellum is by far the most frequent site, these lesions also tend to occur in the medulla and spinal cord. Most haemangioblastomas are sporadic but up to one quarter are associated with Von Hippel-Lindau disease (VHL). Although a fairly good number of haemangioblastomas were reported, a lack of side-by-side analysis of these reports has resulted in tentative conclusions that merely offer a first glimpse at their clinicopathologic diversity and histogenesis. To remedy this issue, this study presents a literature review concerning these lesions. Medline literature including both relevant monographs and clinicopathological case series. Haemangioblastomas occur either as a part of VHL disease (25-30%, inherited mutation of VHL gene on 3p25-26 chromosome) or as sporadic tumours (often with somatic mutation of VHL gene). They have diverse clinicopathologic presentations with cerebellar lesions having a better prognosis than their brainstem counterparts. Immunostaining is important for separation of haemangioblastomas from other tumours with similar histology. The rich vascularity of haemangioblastomas is due to overexpression of vascular endothelial growth factors. Moreover, 'stromal' cells represent the neoplastic cells of haemangioblastomas and are capable of forming blood islands with extramedullary haematopoiesis.

Abstract
Cases of renal clear cell carcinoma in patients with von Hippel-Lindau disease often exhibit extensive metastasis. Several investigators have shown these tumors to specifically invade central nervous system hemangioblastomas, which are commonly associated with the disease. We report on multiple metastatic events within a single von Hippel-Lindau disease-associated tumor outside the central nervous system, epididymal cystadenoma. The multiplicity of these metastatic events suggests the epididymal cystadenoma as a preferential site of metastasis for von Hippel-Lindau disease-associated renal clear cell carcinoma.

Abstract
A case of metastatic renal cell carcinoma (RCC) to a capillary hemangioblastoma (HAB) of the central nervous system in a 52-year-old woman with von Hippel-Lindau (vHL) syndrome is described. We review the literature on metastatic RCC to HAB, summarize the histologic and immunohistochemical features that can distinguish between the 2 tumors, and comment on the significance of such a finding in terms of the clinical diagnosis of vHL. We found the expression of CAM 5.2, RCC antigen, and CD10 to be strong in RCC and absent in HAB and, conversely, staining with Leu-7, neural cell adhesion molecule, and inhibin-alpha was present in HAB but weak or absent in RCC. These antibodies can be used to differentiate these entities, provided one is astute in recognizing the possibility of their coexistence.

Abstract
CONTEXT Immunohistochemistry (IHC) has become an important tool in the diagnosis of brain tumors. OBJECTIVE To review the latest advances in IHC in the diagnostic neuro-oncologic pathology. DATA SOURCES Original research and review articles and the authors' personal experiences. DATA SYNTHESIS We review the features of new, useful or potentially applicable marker antibodies as well as the new uses of already established antibodies in the area of diagnostic neuro-oncologic pathology, focusing on the use of IHC for differential diagnosis and prognosis. We discuss (1) placental alkaline phosphatase, c-Kit, and OCT4 for germinoma, (2) alpha-inhibin and D2-40 for capillary hemangioblastoma, (3) phosphohistone-H3 (PHH3), MIB-1/Ki-67, and claudin-1 for meningioma, (4) PHH3, MIB-1/Ki-67, and p53 for astrocytoma, (5) synaptophysin, microtubule-associated protein 2, neurofilament protein, and neuronal nuclei for medulloblastoma, (6) INI1 for atypical teratoid/rhabdoid tumor, and (7) epithelial membrane antigen for ependymoma. All the markers presented here are used mainly for supporting or confirming the diagnosis, with the exception of the proliferation markers (MIB-1/Ki-67 and PHH3), which are primarily used to support grading and are reportedly associated with prognosis in certain categories of brain tumors. CONCLUSIONS Although conventional hematoxylin-eosin staining is the mainstay for pathologic diagnosis, IHC has played a major role in differential diagnosis and in improving diagnostic accuracy not only in general surgical pathology but also in neuro-oncologic pathology. The judicious use of a panel of selected immunostains is unquestionably helpful in diagnostically challenging cases. In addition, IHC is also of great help in predicting the prognosis for certain brain tumors.

Abstract
Object
Patients with hereditary cancer syndromes may be at increased risk for the development of tumor-to-tumor metastases. To gain insight into the biological nature of these lesions in the central nervous system (CNS), to determine their prevalence in a familial neoplasia syndrome, and to better define their management, the authors retrospectively examined a series of cases in which metastatic lesions developed within hemangioblastomas in patients with von Hippel–Lindau (VHL) disease.
Methods
The study included all cases of VHL disease in which patients underwent resection of a CNS hemangioblastoma that contained a metastasis or were found at autopsy to have a metastasis to a hemangioblastoma between January 2002 and December 2005 at the National Institute of Neurological Disorders and Stroke (NINDS). Clinical, histopathological, imaging, and surgical and/or autopsy findings were analyzed.
Metastasis to a CNS hemangioblastoma was found in six resected tumors (8% of all hemangioblastomas resected from patients with VHL disease at the NINDS during the study period) from six patients (five women, one man; mean age at surgery 42.5 years). The primary site of metastatic disease was the kidney in five patients (renal cell carcinoma) and the pancreas in one (a pancreatic neuroendocrine tumor). Only one patient had systemic metastases at the time of resection of the hemangioblastoma containing the metastasis. Neurologically, all patients had remained at baseline or were improved at last clinical follow-up examination (mean follow-up duration 16.5 months, range 3–40 months). In all cases, postoperative imaging revealed that the hemangioblastoma resection was complete, and there was no evidence of recurrence in any of the patients at the last follow up. Two patients (including one who was also in the surgical group) were found at autopsy to have CNS metastases exclusively to spinal hemangioblastomas.
Conclusions
Hemangioblastomas are an early and preferred site for metastasis in VHL disease. Emerging histopathological techniques may lead to recognition of an increasing number of cases of tumor-to-hemangioblastoma metastasis. Management of cases involving tumor-to-hemangioblastoma metastases in VHL disease should be based on the histological characteristics of the primary tumor, extent of the primary disease, and completeness of the resection.

Abstract
STUDY DESIGN We present the case of a patient with a solitary neoplasm of the intramedullary spinal cord. OBJECTIVE The tumor caused findings of Brown-Séquard syndrome and was the initial presentation of widely metastatic renal cell carcinoma (RCC). SUMMARY OF BACKGROUND DATA Metastasis of the intramedullary spinal cord has been uncommonly reported and is extremely rare as the initial sign of a disseminated carcinoma. METHODS The tumor was resected, and the patient's neurologic deficits slowly improved. The histopathology suggested an epithelioid neoplasm. However, despite expert review, the diagnosis was nonspecific, and the tumor appeared benign. RESULTS It soon recurred in the spinal cord, and repeat imaging studies showed numerous new metastases and a primary renal neoplasm. Biopsy and a repeat histopathologic analysis confirmed RCC, and the patient died of disseminated disease within another 2 months. CONCLUSIONS Despite being uncommon, spinal cord metastases should be considered in some patients before surgery because it may expedite diagnosis, mitigate the need for surgery, and improve the quality of life for these patients. Clinical factors suggesting metastasis include a personal or family history of malignancy or conditions predisposing to it, the presence of multiple tumors in the spinal cord or elsewhere, nonspecific constitutional symptoms, such as weight loss or decreased appetite, and, specifically for RCC, an abnormally increased hematocrit.

Abstract
BACKGROUND Metastases of systemic neoplasia to preexisting intracranial mass lesions are uncommon phenomena. Tumor-to-intracranial cavernoma metastases are even more unusual and rarely reported. We describe here a case of melanoma to intracranial cavernoma metastasis. CASE DESCRIPTION A 39-year-old woman presented after an episode of generalized tonic-clonic seizure on a background of infrequent epilepsy. She was found to have a left parieto-occipital hemorrhagic lesion on imaging studies. The lesion was surgically removed and histopathology showed a metastatic melanoma within a cavernoma. CONCLUSION This case report represents the third recorded case of tumor-to-intracranial cavernoma metastasis and the first melanoma to intracranial cavernoma metastasis. An extensive literature review of tumor-to-intracranial tumor metastases was conducted and disclosed an increase in reporting of the uncommon phenomenon of metastasis into preexisting intracranial lesions. It should therefore be considered as a differential diagnosis in patients with history of systemic cancer who present with progression of preexistent intracranial lesions.

Abstract
✓ The authors describe the case of a patient with von Hippel—Lindau (VHL) disease in which a spinal hemangioblastoma contained metastatic renal cell carcinoma (RCC). The literature on tumor-to-tumor metastasis associated with VHL disease of the central nervous system (CNS) is reviewed.
Midthoracic back pain developed in this 43-year-old man with a left-sided radicular component 2 years after he underwent resection of a left RCC. Radiological findings demonstrated a T6–7 intradural intramedullary lesion. A T5–8 laminectomy and gross-total resection of the spinal cord mass were performed. Light and electron microscopic examination showed features of hemangioblastoma, which contained metastatic foci of RCC. Genetic analysis demonstrated the presence of a deleting mutation in the first exon (nt. 394–406) of the VHL locus, truncating 16 amino acids (N61–77) from the first beta sheet in the VHL protein. A review of the literature revealed that RCC-to-CNS hemangioblastoma is the second most common donor—recipient tumor association among the tumor-to-tumor metastases.

Abstract
BACKGROUND Central nervous system hemangioblastomas (HBs) are uncommon, highly vascularized tumors that are predominantly found in the cerebellum. They occur sporadically or in association with von Hippel-Lindau (VHL) disease. HBs are of unknown histogenesis, and the origin of stromal cells is still a subject of debate. The aim of this study was to investigate the immunoprofile of neoplastic stromal component, and to determine whether the profile of the expression of immunomarkers used can contribute to the elucidation of the histogenesis of HBs. METHODS A series of eight cerebellar HBs were histochemically examined for the detection of mast cells and immunohistochemically for the expression of factor VIII-related antigen (FVIII-RAg), CD34, vimentin, factor XIIIa (FXIIIa), S-100 protein, glial fibrillary acidic protein (GFAP), neuron-specific enolase (NSE), neurofilaments (NF), synaptophysin, chromogranin, and somatostatin. RESULTS Mast cells were present in all hemangioblastomas, and were particularly abundant in one tumor. Immunohistochemically, intense reactivity for vimentin and NSE in the stromal cells was constantly seen. Immunoreactivity with S-100 protein and FXIIIa was variable, but generally many HBs stromal cells were negative for these markers. However, stromal cells were uniformly negative for FVIII-RAg in all HBs investigated. They were negative for CD34, GFAP, NF, synaptophysin, chromogranin, as well as somatostatin. GFAP-positivity of the occasional stromal type cells, located only peripherally, was interpreted as "pseudopositivity". CONCLUSION The immunoprofile of neoplastic stromal component in this study suggested a possible origin from undifferentiated multipotential mesenchymal cells. High expression of NSE (glycolytic and hypoxia-inducible enzyme) in the HBs stromal cells might be related to the loss of the VHL protein function.

Abstract
A case of capillary hemangioblastoma located in the peripheral soft tissue of the inner ankle in a 74-year-old woman is presented. The tumor was an unencapsulated but sharply circumscribed nodule 2.5 cm in size, of a yellow-white color. It showed reddish-brown spots with small cysts up to 2 mm filled with blood. Grossly the tumor was not attached to any peripheral nerve. Signs of von Hippel-Lindau's disease were excluded by thorough clinical evaluation. No additional tumor or erythrocytosis was found in the patient clinically. Immunohistochemically, the tumor stromal cell reacted strongly with antibodies to S-100 protein, NSE, and calponin and they were negative with antibodies to GFAP, CD34, CD31, cytokeratins, actin, desmin, EMA, and HMB-45. Endothelium of the capillaries reacted positively with antibodies to CD31, CD34, and Factor VIII-related protein. Capillary pericytes were actin-positive. All cells of the tumor stained positively with antibody to vimentin. MIB1 antibody reacted only in very few cells (<1%). Ultrastructurally, the stromal cells contained electron-lucent cytoplasm with lipid droplets, a small amount of rough endoplasmic reticulum, and glycogen particles. No electron-dense structures typical of secretory granules were seen in the stromal cells. No mutation of coding sequence of VHL gene was found.
