Abstract
INTRODUCTION Gliofibroma is a rare tumor that develops in the brain and spinal cord. Due to the rarity of its nature, its pathophysiology and appropriate treatment remain elusive. We report a case of intramedullary spinal cord gliofibroma that was surgically treated multiple times. This report is of great significance because this is the first case of recurrence of this tumor. CASE PRESENTATION A 32-year-old woman complained of gait disturbance and was referred to our institution. At the age of 13 years, she was diagnosed with intramedullary gliofibroma and underwent gross total resection (GTR) in another hospital. Based on imaging findings, tumor recurrence was suspected at the level of cervical spinal cord, and surgery was performed. However, the resection volume was limited to 50% because the boundary between the tumor and spinal cord tissue was unclear and intraoperative neuromonitoring alerted paralysis. At 1 year postoperatively, the second surgery was performed to try to resect the residual tumor, but subtotal resection was achieved at most. At 2 years after the final surgery, no tumor recurrence was observed, and neurologic function was maintained to gait with cane. DISCUSSION Although complete resection is desirable for this rare tumor at the initial surgery, there is a possibility to recur even after GTR with long-term follow-up. During surgical treatment for tumor recurrence, fair adhesion to the spinal cord is expected, and reoperation and/or adjuvant therapy might be considered in the future if the tumor regrows and triggers neurological deterioration.

Abstract
BACKGROUND Gliosarcomas are malignant tumors of the central nervous system. As a variant of glioblastomas (GBM), they are treated in a similar fashion. However, there is growing evidence to suggest that they may be a separate entity. METHODS Due to the rarity of primary gliosarcomas (PGS), here we publish data from a single center spanning over 14 years, comprising possibly one of the biggest case series in the literature to our knowledge. RESULTS The mean age at presentation was 59 years with male preponderance (1.75:1). The most common presenting symptoms were balance and mobility issues (61%), followed by headaches (50%) and visual problems (39%). Tumours were most likely to involve the frontal and parietal lobes (27% and 21% respectively). Patients under 50 had a significant survival advantage (50% versus 32%). All patients had surgery, 79% had adjuvant radiotherapy, with a further 21% also receiving chemotherapy. Median survival from surgery of patients diagnosed with PGS was 6.6 months. Median and one-year survival were significantly better for patients who received radiotherapy (14 months; 46% one year survival) and improved further with combined radio- and chemotherapy (30 months; 77%, one year survival). CONCLUSIONS For patients of good functional status, adjuvant chemo-radiotherapy is warranted and should be offered as it confers a much-improved overall survival.

Abstract
Gliofibroma is an extremely rare biphasic tumor with an astrocytic and benign mesenchymal component, which commonly occurs within the first two decades of life. The exact biological behavior of the tumor is not fully understood. Therefore, it is not listed as a distinct entity in the current World Health Organization classification of central nervous system tumors. Here, we describe a rare case of gliofibroma, which was located on the medial temporal lobe in a 61-year-old woman. Preoperatively, we misdiagnosed it as a meningioma because it was a well-demarcated and well-enhanced extra-axial mass with calcification and bony destruction. On the histopathological and immunohistochemical examination, the tumor consisted of a mixture of glial tissue and mesenchymal tissue and it was finally diagnosed as a gliofibroma. To our knowledge, this case of intracranial gliofibroma is in the oldest patient ever reported.

Abstract
Gliofibroma is a relatively rare variant of a mixed glial-fibrous tumor more frequent in children than in adults. It has been reported to appear all along the neuraxis, with predilection for the midline. Its evolution is usually benign, although few examples have shown either multiple sites of involvement or leptomeningeal dissemination. Some authors regard it as part of the desmoplastic astrocytoma spectrum. We report here four examples of this rare condition which exemplify its histological patterns and biological behavior, and provide a review of the literature. Even though this tumor is commonly regarded as heterogeneous and with variable course, our literature review points to a set of clinical and pathological traits that are constant, such as age, location and gross and histological characteristics, as well as a predictable evolution. Currently, this tumor is not included in the WHO Classification of CNS tumors.

Abstract
We report a 50-year-old woman with no relevant clinical history who presented with headache and loss of memory. Magnetic resonance imaging showed a left parieto-temporal mass with annular enhancement after contrast media administration, rendering a radiological diagnosis of high-grade astrocytic neoplasm. Tumour sampling was performed but the patient ultimately died as a result of disease. Microscopically, the lesion had areas of glioblastoma mixed with a benign mesenchymal constituent; the former showed hypercellularity, endothelial proliferation, high mitotic activity and necrosis, while the latter showed fascicles of long spindle cells surrounded by collagen and reticulin fibers. With approximately 40 previously reported cases, gliofibroma is a rare neoplasm defined as either glio-desmoplastic or glial/benign mesenchymal. As shown in our case, its prognosis is apparently determined by the degree of anaplasia of the glial component.

Abstract
Gliofibroma is a rare tumor with biphasic morphology, commonly occurring in the first two decades of life. Currently, the tumor is not listed as a distinct entity in the current World Health Organization (WHO) classification of central nervous system tumors. As its biological behavior, histogenesis, and prognostic factors are still debated, the aim of this paper was to describe a case of a gliofibroma and to update the data about these lesions. Hence, we present here clinical symptoms, pathological findings, and evolution observed in a child with gliofibroma. A 10-year-old girl with seizures was referred for study. Neuroimaging showed a hemispheric hyperdense tumor with little peritumoral edema and no mass effect. The tumor was totally removed. Histologically, the tumor consisted of a mixture of glial cells and collagen-rich stroma. Immunohistochemical examination revealed positive staining for GFAP, CD 99, S100, and vimentin. EMA staining showed a paranuclear dot pattern in only few cells in isolated areas. These findings of a glial component with collagenous stroma were consistent with a desmoplastic glioma. Because of the rarity of this entity, we believe it is important to report every case in order to adequately analyze and categorize the tumor in the next WHO classification.

Abstract
Primary gliosarcoma (PGS) is a rare neoplasm with a poor prognosis. It is considered as a variant of glioblastoma multiforme (GBM) and as a grade IV neoplasm. There is little evidence on the optimal therapy for this disease: treatment of PGS includes surgery, radiotherapy and chemotherapy, and often the same treatment used for GBM is employed for PGS. Several studies have demonstrated that somatostatin receptors are overexpressed in gliomas; somatostatin analogues could therefore also be employed in this mixed form but to date the experience reported in the literature is unclear and there are no studies about the use of these agents in PGS. We present the case of a patient affected by both PGS and neuroendocrine pancreatic cancer. The case is interesting for the prolonged survival and for the stabilization of disease obtained during therapy with somatostatin analogues.

Abstract
INTRODUCTION Gliosarcoma is a very rare primary mixed tumor in the central nervous system, with a biphasic pattern consisting of glial and malignant mesenchymal elements. Its onset is between the fourth and sixth decade of life, and it has a male/female ratio of 1.8/1. Here we present two cases of Gliosarcoma treated in our department. DISCUSSION The monoclonal or biclonal origin of its biphasic nature is still subject to debate; hence the importance of its diagnosis and histogenesis. RESULTS Standard treatment consists in surgical resection of the tumor followed in some cases by external radiotherapy and chemotherapy.

Abstract
Background Glioblastoma multiforme (GBM, WHO grade IV) is the most common and most malignant of astrocytic brain tumors, and is associated with rapid invasion into neighboring tissue. In other tumor types it is well established that such invasion involves a complex interaction between tumor cells and locally produced extracellular matrix. In GBMs, surprisingly little is known about the associated matrix components, in particular the fibrillar proteins such as collagens that are known to play a key role in the invasion of other tumor types. Methodology/Principal Findings In this study we have used both the Masson's trichrome staining and a high resolution multiple immunofluorescence labeling method to demonstrate that intratumoral fibrillar collagens are an integral part of the extracellular matrix in a subset of GBMs. Correlated with this collagen deposition we observed high level expression of the collagen-binding receptor Endo180 (CD280) in the tumor cells. Further, interrogation of multiple expression array datasets identified Endo180 as one of the most highly upregulated transcripts in grade IV GBMs compared to grade III gliomas. Using promoter analysis studies we show that this increased expression is, in part, mediated via TGF-β signaling. Functionally, we demonstrate that Endo180 serves as the major collagen internalization receptor in GBM cell lines and provide the first evidence that this activity is critical for the invasion of GBM cells through fibrillar collagen matrices. Conclusions/Significance This study demonstrates, for the first time, that fibrillar collagens are extensively deposited in GBMs and that the collagen internalization receptor Endo180 is both highly expressed in these tumors and that it serves to mediate the invasion of tumor cells through collagen-containing matrices. Together these data provide important insights into the mechanism of GBM invasion and identify Endo180 as a potential target to limit matrix turnover by glioma cells and thereby restrict tumor progression.

Abstract
This report presents the historical experience, clinical presentation, treatment, prognosis, and pathogenesis of gliosarcoma described to date in the English literature. PubMed query of term “gliosarcoma” was performed, followed by a rigorous review of cited literature. Articles selected for analysis included: (1) case reports of gliosarcoma, (2) review articles of gliosarcoma, and (3) studies of the pathogenesis or genetics of gliosarcoma in humans. Our review identified 219 cases of gliosarcoma in 34 reports and eight articles addressing the pathogenesis. Survival in larger series ranged 4–11.5 months. Features unique to gliosarcoma compared to glioblastoma (GBM) include their temporal lobe predilection, potential to appear similar to a meningioma at surgery, repeated reports of extracranial metastases, and infrequency of EGFR mutations. Published experience is limited to small case series, and the pathogenesis remains unclear. Clinical and pathologic characteristics distinct from GBM suggest that they may warrant specific treatment, separate from conventional GBM therapy.

Abstract
Malignant glioma is the most common primary brain neoplasm. Generally, gliomas are not included in the differential diagnosis of enhancing lesions of the central nervous system in patients infected by the human immunodeficiency virus. We report a case of gliosarcoma in a patient with AIDS presenting as a single cerebral lesion. Stereotactic brain biopsy was obtained and definitive histopathological diagnosis of gliosarcoma was made. A decline in the incidence of opportunistic infections associated with highly active antiretroviral therapy suggest the importance of early stereotactic biopsy to confirm the diagnosis of these neoplasms.

Abstract
A case of psammoma body rich gliofibroma is reported. Computed tomography (CT) showed a high-density mass without contrast enhancement in the right cerebellar hemisphere. Magnetic resonance images (MRI) demonstrated a mass with a mixture of high- and iso-intensity regions without meningeal attachment on both T1- and T2-weighted images. Pathological examinations revealed a biphasic pattern consisting of tumor cells in sparce cellularity and dense fibrous connective tissue. Numerous psammoma bodies of uniform size were found in the stroma. The tumor cells expressed glial fibrillary acidic protein and S-100, but not p53, vimentin and EMA. This is the first report describing a case of psammomatous gliofibroma.

Abstract
Gliofibromas are rare glio-mesenchymal tumors composed of astrocytic and benign mesenchymal components, which commonly occur in the first two decades of life. They are not listed as a distinct entity in the current WHO classification of CNS tumors. Their biological behaviour is unknown, and histogenesis is debatable. We describe a case of histopathologically proven gliofibroma in the region of the left quadrigeminal plate in a 15-year-old child that mimicked a tentorial meningioma both at imaging and surgery. Post-operatively, the residual tumor regrew to a size similar to the initial mass (4 cm x 3.6 cm x 3.5 cm), within one and a half years after the first surgery. The histopathology of the tumor was similar on both occasions. Although a poor prognosis has been characteristically noted in gliofibromas with high-grade glial component, but the present case had recurrence despite being of low-grade, thus highlighting the uncertain behaviour of this rare tumor.

Abstract
Gliofibromas are bimorphic tumors of the central nervous system. Although they are composed of astrocytic and fibroblastic elements, their histogenesis is not clear. An attempt has been made to classify the tumors as low- or high-grade based on morphology and proliferative labeling index, but the clinical behavior and the optimal therapeutic strategies remain unknown. Although they are considered benign, the authors' review shows a 23% mortality rate. The authors report the successful use of carboplatinum and vincristine as treatment of this disease.

Abstract
Gliosarcoma is a rare tumor of the central nervous system, consisting of gliomatous and sarcomatous elements. We present an unusual case of gliosarcoma which demonstrated a variation in phenotype over a six month period, changing from a gliosarcoma with osteosarcomatous differentiation, to a gliosarcoma with no osteosarcomatous component. The initial histological diagnosis was glioblastoma multiforme. Fifteen months later the tumor had transformed into a gliosarcoma demonstrating osteosarcomatous differentiation, with the majority of the tumor consisting of osteoid matrix. Further samples taken six months later revealed gliosarcoma with almost no osteosarcomatous component. It is recognized that glioblastoma can undergo a change in phenotype, transforming into a gliosarcoma. This case demonstrates that ongoing changes in phenotype can occur, especially when the tumor has been treated with chemotherapy and radiotherapy. An understanding of the pathological progression of gliosarcoma will become increasingly important as novel treatments for gliosarcoma and glioblastoma become available.

Abstract
An extra-axial nodule in the cerebello-medullary fissure is described, occurring in a 27-year-old-woman. MRI and CT scans revealed the lesion was a non-enhanced round mass, which was associated with mild atrophy of the surrounding cerebellum, but with no perifocal edema. In the surgical observation, the mass was white, elastic and hard, well demarcated and localized in the cerebello-medullary fissure. Histologically, the lesion was composed of astrocytes and collagen-producing fibroblasts with no anaplasia. These findings suggested that the lesion was hamartomatous, but not neoplastic. This type of gliofibrous nodule has not been previously reported.

Abstract
The present case report describes a case of ganglioglioma with a distinct sarcomatous component in the left temporal lobe of a 59-year-old Japanese man. Neoplastic neuroglial tissue contained both benign and anaplastic glial components with a MIB-1 labeling index of 0.1% and 12.0%, respectively. Sarcomatous tissue adjacent to the anaplastic glial tissue was dominated by pleomorphic fibroblastic cells with a MIB-1 labeling index of 10.8%. They were immunoreactive for smooth muscle actin, type IV collagen, and alpha 1 antitrypsin, but not for desmin and CD34. Interestingly, some of the sarcomatous cells were double-positive for smooth muscle actin and GFAP. The p53 protein had accumulated in the anaplastic astrocytes and sarcomatous cells, but direct DNA sequencing of PCR products failed to detect any mutation in the p53 gene (from exon 4 to exon 10).

Abstract
A 55-year-old female presented with a unique case of gliosarcoma with a huge cystic component manifesting as loss of consciousness, left-sided hemiparesis, and anisocoria. Computed tomography demonstrated a large cyst in the right frontal lobe, and enhancement of the mural nodule after administration of contrast medium. Emergent operation was performed. Xanthochromic fluid was aspirated, and the tumor was resected. The histological diagnosis was gliosarcoma based on the presence of gliomatous and sarcomatous components. She underwent a second operation because of tumor regrowth 3 weeks after the first operation. The postoperative course was satisfactory during radiation therapy with 60 Gy and chemotherapy. The diagnosis of gliosarcoma was difficult to make preoperatively because of the neuroradiological findings similar to low-grade gliomas. Gliosarcoma should be included in the differential diagnosis of huge cystic tumors.

Abstract
Gliofibromas are rarely encountered astrocytic tumours comprising of astrocytic and benign fibroblastic components. They commonly occur in first two decades of life. However, the exact behaviour is not fully known and their histogenesis is also still debatable. We report three cases of gliofibroma in which we studied proliferative markers (MIB-1) and p53 protein expression. In these tumours, occurrence in adult life is in contrast to that reported in the literature. Depending upon the morphology and proliferative Labelling Index we classified these tumours into low grade (benign) and high grade (malignant/anaplastic).

Abstract
Primary brain tumors with prominent desmoplasia include the gliofibroma, desmoplastic infantile ganglioglioma (DIG), pleomorphic xanthoastrocytoma (PXA), and desmoplastic cerebral astrocytoma. In the present report, we describe unusual pathological appearances in two successive resections of a left temporal tumor in a patient with complex partial seizures. Both tumors showed focal astroglial and very prominent neuronal differentiation. In the first resection at age 11 years, the tumor showed only focal desmoplastic areas and prominent neuronal differentiation with bizarre atypical giant cells. In the second resection at age 14 years, the morphology was dramatically different. Now the tumor showed marked desmoplasia with tumor cells coexpressing neuronal and glial markers. Electron microscopy showed prominent neuronal differentiation in both resections and presence of basal lamina around tumor cells. Our case represents a unique example of an extraordinary degree of neuronal differentiation in a desmoplastic cerebral tumor. While cellular pleomorphism in a desmoplastic tumor traditionally suggests the diagnosis of PXA, we wish to underscore that many cells exhibiting marked cytologic atypia may in fact be of neuronal rather than of glial origin as in our case.

Abstract
BACKGROUND Thirty-one gliosarcomas (25 nonirradiated and 6 postirradiated tumors) were selected based on the presence of two distinctive areas: a malignant gliomatous and a sarcomatous component. In all cases, the sarcomatous component appears like fibrosarcoma or malignant fibrous histiocytoma. Two tumors showed additional areas consisting of osteochondroid differentiation. METHODS All tumors were examined using antibodies against Ulex europaeus agglutinin I (UEA), glial fibrillary acidic protein (GFAP), vimentin (VM), epithelial membrane antigen (EMA), desmin, collagen IV, alpha-1-antitrypsin (alpha-1-AT) and smooth muscle actin (SMA). RESULTS While the VM highlighted the sarcomatous areas of all tumors there were only scattered spindle cells that were GFAP-positive in the same areas. The alpha-1-AT was diffusely reactive in the sarcomatous areas in 20 cases. Focal immunoreactivity was seen with SMA (20 tumors), UEA (8 tumors), EMA (5 tumors), collagen IV (5 tumors) and desmin (4 tumors) in the nonvascular sarcomatous cells. CONCLUSIONS The range of immunophenotypical expression is likely to be a reflection of the capacity of a multipotential progenitor to undergo divergent differentiation. There is a very little morphological difference between the postirradiated and nonirradiated tumors except that a higher proportion of postirradiated tumors are immunoreactive to SMA and desmin.

Abstract
Gliofibromas are rarely encountered astrocytic neoplasms characterized by an admixture of astrocytic and fibroblastic cell components. The exact nature of these rare tumors are still a matter of considerable debate. This article reports a case of gliofibroma occurring in a 3-month-old boy. The astrocytic component of the tumor stained diffusely positive for glial fibrillary acidic protein (GFAP) and S-100 protein. Prominent reticulin staining was observed within the fibroblastic component of the tumor. The MIB1 labeling index (positive number of tumor cells divided by total tumor cells counted X 100) was low (0.9), supporting the general slow growth of these tumors. Immunohistochemical staining with antibody against p53 protein was negative. Gliofibromas seem to be a low-grade variant of an astrocytoma that shares many features with other desmoplastic astrocytic neoplasms (desmoplastic infantile astrocytoma, desmoplastic infantile ganglioglioma) including a generally favorable prognosis.

Abstract
BACKGROUND Gliosarcoma is an uncommon malignant brain tumor with mixed glial and mesenchymal elements. Experience is limited to case series, and pathologic data are disparate, leading to uncertainty about clinical features, management, and histogenesis. METHODS A clinicopathologic review of 32 patients with survival analysis and immunohistochemical studies was performed including glial fibrillary acidic protein analysis, alpha-1-antitrypsin (alpha-1-AT) analysis, and smooth muscle actin (SMA) analysis. RESULTS Twenty-five patients had primary gliosarcoma, whereas 7 developed gliosarcoma after irradiation for glioblastoma multiforme (GBM). Clinical features were similar to those of GBM. Most tumors were intraaxial and diffusely infiltrating by radiologic studies and at surgery. Median survival for primary gliosarcoma was 25 weeks overall, with patients who received irradiation surviving longer (46 vs. 13 weeks, P < 0.025). Gliosarcoma occurring after irradiation appeared hyperdense by computed tomography in five of seven cases, and median survival was 53 weeks. Primary gliosarcoma was a dimorphic tumor with malignant glial elements and features of malignant fibrous histiocytoma (MFH) or fibrosarcoma and one osteosarcoma. Smooth muscle actin labeled tumor vessels heavily, but in 15/25 primary cases, it extended to the surrounding spindle cells. The remaining cases appeared morphologically like MFH and tended to be positive for alpha-1-AT. Postirradiation gliosarcoma was fibrosarcomatous with positive SMA in 75% of the cases examined. CONCLUSIONS Gliosarcoma behaves clinically like GBM, and survival may be improved by cranial irradiation of selected patients. Smooth muscle actin reactivity in sarcomatous areas suggests histogenesis in some tumors from the smooth muscle within GBM, whereas others may arise via different mechanisms including differentiation from a pluripotential precursor. Transformation of the smooth muscle within GBM may have therapeutic implications for antiangiogenesis agents.

Abstract
We report a case of a 24-year-old woman with left temporal pleomorphic xanthoastrocytoma (PXA) with atypical neuronal cells. Many neoplastic cells, otherwise typical of PXA, expressed glial fibrillary acidic protein, while neuronal cells with marked atypia were immunopositive for synaptophysin and neurofilament protein. This report supports a notion that PXA, like other astrocytic tumors, may have its gangliogliomatous counterpart.

Abstract
A 7-year-old girl presented with focal seizures without symptoms of raised intracranial tension. Routine histological, immunocytochemical and ultrastructural methods revealed a desmoplastic low grade cerebral astrocytoma. Follow up for 2 years after biopsy did not show recruitment of neurological symptoms or signs. Biphasic tumours containing glial and mesenchymal elements have been described in the literature under various diagnostic headings. As the histologically benign variants of mixed glial and mesenchymal tumours appear to have a good prognosis, identification of these as separate entities seems imperative. With a review of literature we propose a pathological classification of mixed glial and mesenchymal tumours.

Abstract
The communication between tumor cells and extracellular matrix (ECM) is responsible for clinically important features of malignant gliomas, such as cerebral invasion and leptomeningeal spread. The synthesis of ECM components, ECM-degrading activities and ECM receptors as well as the interaction between ECM components and their receptors represents the molecular basis for these processes. Recent studies have shown that proteases and integrins, the major group of ECM receptors, may be over-expressed by astrocytic tumor cells. Furthermore, integrins and the hyaluronate receptor CD44 have been found to be involved in adhesion and basement membrane invasion of glioma cells. Critical issues which are poorly understood so far include the ECM composition of the normal human brain and of brain tumors, the function of individual ECM components and receptors in a neuro-oncological context, and the molecular processes mediating the diffuse invasion of glioma cells into the brain.

Abstract
A 57-year-old woman with primary intracerebral osteosarcoma is reported. The tumor was identified by computed tomography as a mass with hemorrhage in the right parietal lobe. The surgical and pathological examinations confirmed an osteosarcoma of intracerebral origin. She suffered from repeated local recurrence of the tumor and died about 1 year after the onset. The pathological findings showed features of osteoblastic osteosarcoma with numerous osteoclast-like multinucleated giant cells. Immunohistochemically, tumor cells were positive for vimentin, and partially for actin. Multinucleated giant cells were reactive with vimentin and CD68 antibodies. Ultrastructurally, tumor cells were rich with rough endoplasmic reticulum. These findings are consistent with the histological features of skeletal or extraskeletal osteosarcoma. This is the third case of primary intracerebral osteosarcoma reported in the literature and the first one analyzed ultrastructurally.

Abstract
To analyze the process of mesenchymal differentiation in vitro, we examined 5 human glioblastomas as biopsy specimens, monolayer cultures and 3-dimensional fragment spheroid cultures for the immunohistochemical expression of extracellular matrix (ECM) components (collagen types I, III-VI, laminin) and integrin receptors (beta 1, beta 2, beta 3 and beta 4 chains). mRNA for type-I and type-IV collagen alpha I chains was quantified using reverse transcription-polymerase chain reaction. In situ, glioma cells expressed beta 1, the common beta chain of most integrin ECM receptors, while ECM components were restricted to vascular elements. Early monolayer cultures showed a marked increase in ECM components (interstitial collagens more than basement membrane components), and coexpression of ECM components and glial fibrillary acidic protein (GFAP) by most cells. beta 2 and beta 3 integrins were upregulated in the primary cultures. In the fifth passages, GFAP-positive cells were decreased and collagen-expressing cells increased. The spheroids exhibited preserved GFAP staining, neoexpression of beta 4 integrin in some tumors, and variable ECM expression by glioma cells which was lower than that in monolayer cultures. ECM deposition usually commenced in central spheroid areas where the Ki-67 proliferation index was low. We conclude that different culture systems are characterized by distinct expression patterns for ECM components and receptors, and that mesenchymal features in cultured gliomas arise due to transdifferentiation of glioma cells.

Abstract
The immunohistochemical localization of glial fibrillary acidic protein has proven its utility in the histologic identification of benign astrocytes and neoplastic cells of glial lineage in the central nervous system. Its application in the developing nervous system has contributed significantly to following the histogenesis of neural tissue. Its identification in various forms of injury and neoplasia has helped in discovering the function of astrocytes in these processes. In diagnostic neuropathology, its greatest contribution has been in the elucidation of the cellular constituencies of neoplasms previously considered of enigmatic origin.

Abstract
Basement membrane invasion precedes meningeal dissemination and systemic metastasis of glioma cells. In order to investigate the invasive ability of glioblastomas and the functional role of extracellular matrix receptors, the authors performed in vitro invasion assays where the number of cells was determined from freshly resected tumors (primary cultures and fifth passages) and from cell lines (U-138 MG, U-373 MG, and GaMg) that had migrated through a filter coated with a reconstituted basement membrane (Matrigel). The involvement of integrin adhesion molecules was examined by preincubation of glioma cells with blocking antibodies to specific integrin chains. Cells from all of the glioblastomas had migrated through the Matrigel after 4 to 24 hours; the number of invasive cells was highest in the cell lines. Invasion of U-138 MG cells was reduced with antibodies to alpha 7, alpha v, beta 1, and beta 3 integrin chains and markedly increased by anti-alpha 5, while invasion of U-373 MG cells was reduced by antibodies to alpha 3, alpha v, beta 1, and beta 3 and increased by anti-alpha 6. It is concluded that: 1) glioma cells are able to penetrate Matrigel, indicating that the basement membrane is not a resistant barrier for infiltrating cells; and 2) basement membrane invasion is mediated by integrins in a complex manner. Some integrins promote while others inhibit basement membrane invasion. Furthermore, the integrins involved may differ between various glioma cells.

Abstract
Interphase cytogenetics, i.e., in situ hybridization using probes to chromosome-specific DNA, enables histological identification of cells bearing numerical chromosome aberrations and cytogenetic analysis of composite tumors. We studied routinely processed tissues from seven glioblastomas and three gliosarcomas using biotinylated probes to pericentromeric alpha-satellite sequences on chromosomes 10, 17 and X. By applying various pretreatment protocols, an evaluable compromise between morphology and signal intensity was obtained in most cases. Compared to vascular cells with normal chromosomal counts, a significant subpopulation of glioblastoma cells showed monosomy 10 (four of five cases), monosomy 17 (one of seven cases) and loss of one X chromosome (one of seven cases). All monosomy 10 cases comprised additional areas where two copies of chromosome 10 were retained. Among the gliosarcomas, both the glioma and the sarcoma portion showed monosomy 10 in one case and monosomy 17 in another case. In contrast, in the third case of gliosarcoma, monosomy 10 was found only in the glioma portion, whereas a gain of chromosome X was observed in the sarcoma portion. We conclude that: (1) numerical chromosome aberrations can be detected in routinely processed brain tumor biopsy specimens using interphase cytogenetics, making retrospective studies feasible; (2) glioblastomas show intratumoral cytogenetic heterogeneity with formation of monoclonal cell clusters; and (3) sarcoma and glioma elements in gliosarcomas may exhibit the same or different numerical chromosome aberrations, suggesting various histogenetic pathways of the sarcoma-like portion.

Abstract
We present a case of desmoplastic cerebral astrocytoma of infancy (DCAI) in a 7 1/2-month-old girl and include immunohistochemical, ultrastructural and proliferative activity studies. The dural-based cystic tumor showed a biphasic pattern consisting of glial fibrillary acidic protein (GFAP)-positive astrocytes embedded in a desmoplastic stroma. The astrocytic processes were lined with basal lamina at their surface contacting the collagen. Scattered islands of undifferentiated small cells were seen acquiring GFAP positivity at their peripheral zone facing the collagen. Studies with silver nucleolar organizer region and proliferating cell nuclear antigen disclosed a high proliferative activity. Flow cytometric study showed an elevated S phase and 15% hypertetraploid cell population. These findings contrast the favorable prognosis of the tumor at 26 months follow-up. Probably, extracellular-matrix-induced maturation of the undifferentiated cells with the formation of basal lamina may account for this unique disparity.
