Abstract
Peripheral nerve sheath tumours are rare in pigs. In the present case, a juvenile female hybrid pig showed a solitary, pigmented, cutaneous mass. Histologically, it consisted of clustered melanin-laden, epithelioid cells as well as spindle cells forming bundles and nodules. The latter were surrounded by perineurial-like cells. Single Wagner-Meissner-like corpuscles were present. Immunohistochemically, the epithelioid cells expressed S100 protein, melan A and the p75 neurotrophin receptor (p75NTR). The spindle cells expressed S100, sex determining region Y-box 2, p75NTR, Krox20, growth associated protein 43 and glial fibrillary acidic protein. Perineurial-like cells were positive for p75NTR, α-smooth muscle actin and cytokeratin. Taken together, the histological und immunohistochemical findings support the diagnosis of a cutaneous pigmented neurofibroma.

Abstract
The Alagille syndrome (AGS) or arteriohepatic dysplasia is a rare, autosomal dominant inherited disease with a prevalence of approximately 1:100,000. AGS was first described in 1969 and affects liver, heart, arterial blood vessels, skeleton and the eyes. The expression of AGS is variable. In severe cases a liver transplantation is required. Presented is the case of a 25-year-old woman with AGS. At the age of 7 and 8years she had liver transplantations. Other typical findings associated with Alagille syndrome (e.g. pulmonary or renal anomalies) were also present. The young woman apparently died suddenly and unexpectedly in a good health condition despite regular medical treatment. Cause of death was a subarachnoid hemorrhage with invasion of the hemorrhage into the ventricle system caused by a rupture of previously unknown large aneurysm in the terminal basilary artery. Intracranial vascular malformations are a common finding in patients with AGS and cause death in up to 16% of them. Life expectancy in AGS patients depends on the severity of changes of the affected liver. But AGS is also responsible for various vascular abnormalities in several other organs which can cause lethal complications. Due to the high rate of vascular complications and intracranial hemorrhage with the leading cause of mortality in patients with AGS, vascular screening by the use of noninvasive imaging techniques (CT or MR angiography) is required to avoid unexpected sudden death.

Abstract
Neurological cases, especially in foals, are rare in the daily practical work. The most common causes are traumata and infectious diseases of the central nervous system (CNS). This case report provides further insights into the wide spectrum of possible neuropathological lesions by detailing a complex malformation with unilateral neurological signs that occurred later post natum. Thus, clinicians should also be aware of malformations in case of respective neurological patients. A Hanoverian foal was presented with progressive ataxia. General and blood examination revealed no further alterations. By neurologic examination, a unilateral hypermetria was diagnosed and a cysternography of the head was performed. A cerebellar malformation was assumed and the foal was euthanized due to poor prognosis. At necropsy, a unilateral absence of a cerebellar hemisphere and vermis accompanied by contralateral malformation of the mesencephalon was diagnosed. The missing areas of the right cerebellar hemisphere were replaced by a cystic formation. The left part of the mesencephalic lamina quadrigemina was reduced in size and the corpus callosum was hypoplastic. Additional microscopical findings were most obvious near the cyst formation and included angiofibrosis in remaining cerebellar and mesencephalic parenchyma and leptomeninges, heterotopia of cerebellar neurons, sclerosis in cerebellar cortex, focal proliferation of meningeal cells and mild mononuclear perivascular infiltrates. Occassional irregular neuronal arrangement in the mesencephalon was also present. Infectious agents such as Borna disease virus, rabies virus, and equine herpesvirus were not detected. Therefore, the complex malformation in this foal might have been caused by a destructive, possibly ischemic event, or could represent a sequel of a primary retrocerebellar cyst with accompanying compression of adjacent parenchyma.

Abstract
Aprosencephaly is a rare condition in veterinary and human medicine characterized by the complete absence of telencephalon and diencephalon. Some cases are accompanied by a facial dysmorphism designated as otocephaly. A stillborn lamb had splanchnocranial anomalies that were classified by computed tomography, magnetic resonance imaging, and pathologic examination as aprosencephaly and otocephaly. The brain included parts of the cerebellum and brainstem but no telencephalon, diencephalon, or mesencephalon. The cerebellum had a structurally normal cortex with expression of neuronal nuclear antigen in the inner and doublecortin in the outer granular cell layers, as well as an irregularly situated nucleus dentatus. Aprosencephaly with otocephaly has been described in mice with heterozygous mutations in the Otx2 gene; however, no causative polymorphisms were detected in the Otx2 gene region of this lamb.

Abstract
Glioblastoma multiforme (GBM) is the most common and most malignant primary brain tumour. Protein tyrosine phosphatase interacting protein 51 (PTPIP51) is an interaction partner of 14-3-3β, which correlates with the grade of malignancy in gliomas. In this study PTPIP51 and its interacting partners 14-3-3β, PTP1B, c-Src, Raf-1 as well as EGFR were investigated in human glioblastoma. Twenty glioblastoma samples were analyzed on transcriptional and translational level by immunohistochemistry, in situ hybridization and RT-PCR. To compare PTPIP51 expression in gliomas of different malignancies, quantitative RT-PCR for grade II astrocytoma and GBM samples was employed. Additionally, we analyzed the correlation between PTPIP51 and 14-3-3β transcription, and checked for in situ interaction between PTPIP51 and 14-3-3β and PTP1B, respectively. PTPIP51 and 14-3-3β mRNA showed a tumour grade dependent upregulation in gliomas. Glioblastoma cells displayed a strong immunoreaction of PTPIP51, which co-localized with 14-3-3β and PTP1B. The duolink proximity ligation assay corroborated a direct in situ interaction of PTPIP51 with both proteins, known to interact with PTPIP51 in vitro. The in vitro interacting partners Raf-1 and c-Src showed a partial co-localization. Besides, immune cells located in capillaries or infiltrating the tumour tissue and endothelial cells of pseudoglomerular vessels revealed a high PTPIP51 expression. The upregulation of PTPIP51 and its connection with the EGFR/MAPK pathway by 14-3-3β via Raf-1 and by PTP1B via c-Src, argue for a functional role of PTPIP51 in the pathogenesis of human glioblastoma.

Abstract
INTRODUCTION An intracranial plasmacytoma is a rare form, which can involve the calvarium, dura or the cranial base. Only few case reports describe the manifestation of plasmacytoma of the skull base with affection of visual acuity. CASE REPORT We describe the case of a 43-year-old woman, presenting with an acute unilateral loss of vision. The presumption diagnosis was retrobulbar neuritis as first manifestation of multiple sclerosis. MR imaging disclosed a tumour in the left orbital region and a meningioma was suspected. After complete resection with decompression of the optic nerve, the neuropathological examination revealed a lambda positive plasmacytoma. Additional work-up disclosed an involvement of multiple vertebral bodies. Due to the diagnosis of multiple myeloma, oncological therapy had been initiated. CONCLUSION Skull base plasmacytoma is a rare disease. Solitary lesions causing neurological deficits should be treated aggressively including surgery for histological diagnosis and decompression of neural structures. Prognosis and further therapy depends on the systemic stage of disease, which has to be defined by diagnostic work-up.

Abstract
We present the case of a 13-month-old girl with a right occipital cortical alteration on MRI that proved to be a growing lesion. Tumor growth had been observed over a period of 15 months before total resection was performed, revealing a dysembryoplastic neuroepithelial tumor WHO grade I. This case shows that dysembryoplastic neuroepithelial tumors can present as growing neoplasias. It underlines the importance of obtaining histologic diagnosis and close follow-up examinations using MRI, even in so-called stable lesions that are only unveiling through epileptic seizures.

Abstract
T-cell lymphoblastic lymphoma is a rare form of non-Hodgkin lymphoma, which shows preponderance for young men. Most common symptoms are painless swelling of lymph nodes, accompanied by B symptoms and large mediastinal masses. Most often, an involvement of the nervous system is due to paraneoplastic symptoms or side effects of treatment. In a literature research, we could not find a case with affection of a cervical nerve root as the first symptom for T-cell lymphoblastic lymphoma. A 39-year-old man presented with right-sided C8 radiculopathy, including pareses and paresthesia. Since the magnetic resonance image disclosed a right-sided mass lesion in the region of the neuroforamen C8, compressing the corresponding nerve root, a schwannoma was suspected. The tumor was removed using a dorsal approach. Neuropathological examination revealed the diagnosis of T-cell lymphoblastic lymphoma. The patient underwent diagnostic staging and received further treatment. He experienced a very grim course and succumbed to his disease 12 months after surgery. T-cell lymphoblastic lymphoma is a rare disease, and tropism of lymphoma cells to neural structures is seldom encountered. However, the presence of radiculopathy, together with signs, referring to B symptoms, should prompt the physician to consider this coincidence in the differential diagnosis of schwannoma.

Abstract
Central neurocytoma is a rare, prognostically favorable neuronal tumor of the human central nervous system, typically located intraventricularly near the foramen of Monro. Extraventricular cerebral neurocytomas and spinal tumors have also been reported. To date, however, neurocytomas have not been documented in domestic animal species. In this report, we describe a spinal cord tumor in a dog. The microscopic examination revealed tumor cells forming loosely packed clusters in some areas and palisades in other areas. In addition, they showed fine fibrillary neuropil-like areas of different sizes, sometimes resembling the "rosettes" of pineocytomas, as well as ependymoma-like perivascular pseudorosettes. The tumor cells had scant eosinophilic cytoplasm, with perinuclear halos, closely resembling the appearance of oligodendroglioma. Immunohistochemical staining showed expression of synaptophysin and neuron-specific enolase by tumor cells and pronounced in fibrillary areas. On the basis of histomorphology and immunohistochemical reactivity, the present tumor was diagnosed as extraventricular neurocytoma.

Abstract
A 3-year-old male Labrador retriever dog was presented with multifocal small cutaneous nodules, distributed mainly over the thoracic wall, the flank and the scrotum. The dog was otherwise in good health and had no significant past medical history. Radio- and sonographic examination revealed no evidence of internal tumours, including endocrine tumours. Histological examination of two excised samples revealed round, non-ulcerated nodules in the superficial corium, characterized by two different neoplastic cell components and mild inflammation. The first tumour cell population showed histomorphological characteristics of mature ganglion cells; the second featured small, spindle-shaped tumour cells with scant cytoplasm. Both neoplastic cell components expressed vimentin, neurofilament protein, pan-neuronal neurofilament, amyloid-precursor protein and chromogranin A. In addition, the spindle-shaped tumour cells were positive for 2', 3'-cyclicnucleotide 3'-phosphodiesterase. The findings had many histological and immunohistochemical features in common with primary cutaneous ganglioneuromas in humans, enabling the canine tumours to be also classified as multiple cutaneous ganglioneuromas.

Abstract
The histopathology of papillary tumours of the pineal region (PTPR) closely resembles that of ependymomas and choroid plexus tumours. Therefore, immunohistochemical staining profiles were investigated in a series of 15 PTPR. In addition to cytokeratin, synaptophysin and glial fibrillary acidic protein expression, PTPR were examined for the presence of dot- or ring-like epithelial membrane antigen (EMA) immunoreactivity typically encountered in ependymoma, staining for inwardly rectifying potassium channel Kir7.1 and stanniocalcin-1 (specifically expressed in choroid plexus tumours) as well as microtubule-associated protein-2 (MAP-2). Furthermore, comparative genomic hybridization was performed in five PTPR. Cytokeratin was expressed in all PTPR examined, whereas glial fibrillary acidic protein and synaptophysin staining were absent. Dot- or ring-like EMA immunoreactivity was only observed in 1 out of 15 PTPR. Membranous Kir7.1 and cytoplasmic stanniocalcin-1 staining were present in the minority of PTPR (3/15 and 4/15, respectively). In contrast, MAP-2 immunoreactivity was encountered in 13 out of 15 PTPR, but was significantly less frequently observed in a series of choroid plexus tumours (7/37). PTPR mainly presented with chromosomal losses affecting chromosomes 10 (4/5 cases) and 22q (3/5 cases) as well as gains on chromosomes 4 (4/5 cases), 8 (3/5 cases), 9 (3/5 cases) and 12 (3/5 cases). To conclude, the majority of PTPR can be distinguished from ependymomas and choroid plexus tumours by absent staining for epithelial membrane antigen, Kir7.1 and staniocalcin-1 as well as the presence of distinct MAP-2 immunoreactivity. Antibodies directed against these antigens are thus expected to be valuable markers in the diagnosis of papillary tumours located in the vicinity of the third ventricle.

Abstract
Chordoid glioma of the third ventricle was recently reported as a novel tumor entity of the central nervous system with characteristic clinical and histopathological features (Brat et al., J Neuropathol Exp Neurol 57: 283-290, 1998). Here, we report on a histopathological, immunohistochemical and molecular genetic analysis of five cases of this rare neoplasm. All tumors were immunohistochemically investigated for the expression of various differentiation antigens, the proliferation marker Ki-67, and a panel of selected proto-oncogene and tumor suppressor gene products. These studies revealed a strong expression of GFAP, vimentin, and CD34. In addition, most tumors contained small fractions of neoplastic cells immunoreactive for epithelial membrane antigen, S-100 protein, or cytokeratins. The percentage of Ki-67 positive cells was generally low (<5%). All tumors showed immunoreactivity for the epidermal growth factor receptor and schwannomin/merlin. There was no nuclear accumulation of the p53, p21 (Waf-1) and Mdm2 proteins. To examine genomic alterations associated with the development of chordoid gliomas, we screened 4 tumors by comparative genomic hybridization (CGH) analysis. No chromosomal imbalances were detected. More focussed molecular genetic analyses revealed neither aberrations of the TP53 and CDKN2A tumor suppressor genes nor amplification of the EGFR, CDK4, and MDM2 proto-oncogenes. Our data strongly support the hypothesis that chordoid glioma of the third ventricle constitutes a novel tumor entity characterized by distinct morphological and immunohistochemical features, as well as a lack of chromosomal and genetic alterations commonly found in other types of gliomas or in meningiomas.

Abstract
The reported liponeurocytoma of the left lateral ventricle in a 35-year-old man represents the fifth recorded case of a supratentorial intraventricular liponeurocytoma. In this location, liponeurocytomas are very exceptional, whereas it is the typical site for classic central neurocytomas. Conversely, neurocytomas of the cerebellum are predominantly liponeurocytomas with until now more than 25 reported cases. Thus, cerebellar liponeurocytoma is the most frequent neuroepithelial CNS tumor with adipose-like cells followed by ependymomas with a lipid component and supratentorial intraventricular liponeurocytoma. Adipose-like cells in neurocytomas may originate by lipidization of tumor cells, metaplastic transformation of neuroectodermal cells into fat cells or by true adipocytic differentiation. The present case showed also focal glial differentiation with GFAP-positivity of some tumor cells as often seen in cerebellar liponeurocytomas but much rarer in central neurocytomas. Pathogenetic and nosologic implications of supratentorial intraventricular liponeurocytomas are discussed. Future WHO tumor classification should consider that liponeurocytomas are not restricted to the cerebellum. Reports on cerebellar liponeurocytomas with a less favorable clinical course suggest a WHO grade II for liponeurocytomas.

Abstract
This study describes the distribution and identity of annexin-1 positive cells in the central nervous system in patients with multiple sclerosis (MS). Glucocorticoid-inducible, anti-inflammatory properties have been ascribed to annexin-1, a member of a family of calcium-binding proteins that are referred to collectively as annexins. We have found annexin-1 to be spatially associated with active MS lesions and demonstrated a stage-dependent expression of annexin-1 in MS plaques. All of the most important pathogenetically involved cells of MS lesions showed a strong annexin-1 reactivity. Both correlation analysis and double staining procedures suggested annexin-1 expression in macrophages and perivascular lymphocytes, where a cytoplasmic reactivity was displayed, whereas in activated, gemistocytic astrocytes it was also concentrated close to the plasma membrane. Although the exact roles of annexin-1 in this setting are still to be determined, a possible contribution to anti-inflammatory processes might be suggested.

Abstract
OBJECTIVE We report the case of a patient with three different malignancies who had a brain metastasis of bronchial adenocarcinoma with infiltrates of CLL lymphocytes and who had been operated for prostate cancer years before. - PATIENT AND RESULTS A 72-year-old man was admitted to our department after a Jacksonian seizure. The MRI showed a left temporal mass lesion. The patient was suffering from chronic lymphocytic leukemia (CLL) for ten years, he had had surgery for prostate cancer eight years ago and the diagnosis of bronchial carcinoma was made during preoperative routine diagnostics. After neurosurgical intervention the histologic examination of the cerebral mass lesion disclosed metastasis of a PSA-negative adenocarcinoma with perivasal infiltrates of lymphocytic leukemic cells. - DISCUSSION There are few reports about patients with three primary malignancies. CLL may play a role in enabling tumor cells to escape the immune response and could facilitate development of the prostate cancer and of a bronchial adenocarcinoma as secondary cancers in this patient. The combined occurrence of adenocarcinoma cells and CLL lymphocytes in the brain metastasis can be explained by impairment of the blood-brain-barrier in the carcinoma metastasis enabling extravasation of circulating leukemic cells.

Abstract
We present the case of a patient with an endolymphatic sac tumour (ELST). This rare tumour entity has only recently been defined and despite a well characterized clinical appearance misdiagnosis as jugular paraganglioma is frequent. A 68-year-old woman was admitted to our Neurosurgical Department with a mass lesion extending from the left temporal bone to the cerebello-pontine angle (CPA). Radiological features were high vascularization, contrast enhancement and destruction of the os petrosum. After preoperative angiographic embolization the tumour was removed in two surgical interventions, first via a lateral suboccipital approach and second by petrosectomy. The lesion proved to be a typical endolymphatic sac tumour by a synopsis of histological, radiological and clinical features. ELST should be taken into consideration in patients with mass lesions in the cerebellopontine angle destroying the petrous bone and resembling paraganglioma. Since slow growth rate and lack of metastases are particular features of ELST, complete resection of the tumour results in long survival times without adjuvant chemo- or radiotherapy.

Abstract
PURPOSE To demonstrate the ocular histopathologic findings in Fryns syndrome, a multiple congenital anomaly syndrome, with characteristic features including Dandy-Walker malformation, cleft palate, diaphragmatic hernia, lung hypoplasia, distal limb anomalies and polyhydramnios. The prevalence is about 0.7 per 10,000 births. Reported ocular features include microphthalmus, "cloudy cornea", irregularities of Bowman's layer, thickened posterior lens capsule and retinal dysplasia. METHODS Case report. The ocular histopathologic and ultrastructural findings in a male fetus with Fryns syndrome who died immediately after his birth at 26th week of gestation are shown. RESULTS An abnormal Descemet's membrane was found in addition to "cloudy corneae". Electron microscopy demonstrated absence of the banded collagen fibrils in Descemet's membrane, indicating corneal endothelial dysfunction. Otherwise, the eye was morphologically normal for its age; none of the other reported ocular features of Fryns syndrome were found. CONCLUSION Corneal endothelial dysfunction might cause abnormal composition of anterior Descemet's membrane and could contribute to the "cloudy cornea" known to occur in Fryns syndrome.

Abstract
A meningioma with cartilaginous areas is described. The tumour arose in the region of the right sphenoid wing in a 74-year-old woman. Histologically, it showed large areas of a typical meningothelial meningioma, among which numerous cartilaginous islands and some chondroid regions, obviously of intermediate (meningothelial/cartilaginous) differentiation, could be seen. Cartilaginous tumour areas showed lower MIB1-labelling indices than typical meningioma regions, where an increased proliferative activity was seen focally. The current WHO classification lists such tumours as metaplastic meningiomas, reflecting the potential of meningioma cells for mesenchymal differentiation. Metaplastic meningiomas may show different metaplasias (xanthomatous, osseous, lipomatous, cartilaginous, etc.). Extensive cartilaginous metaplasias are very uncommon. Identification of typical meningioma areas is the key for the diagnosis of this meningioma variant.

Abstract
A 27-year-old otherwise healthy male presented with an isolated but complete axillary nerve palsy after excessive squash playing. When repeated electromyographic investigations showed no signs of reinnervation in the deltoid muscle, surgery was performed in order to restore nerve function. Intraoperatively, the nerve showed a short segment of thinning about 2 cm distally the nerve's origin from the posterior fascicle. As intraoperative electrophysiological testing was also negative (no electrically evoked nerve action potentials across the lesion) the suspicious nerve segment was resected and nerve continuity restored by sural grafts. Histologically, no intact nerve structures could be found at the site of the thinning. Most likely the lesion was caused by traction forces. Follow-up studies showed reinnervation of deltoid function over time.

Abstract
A 38-year-old man presented with an intracranial extra-axial tumour at the base of the left posterior fossa which proved to be a meningeal melanocytoma. Meningeal melanocytoma is a rare, benign melanotic tumour of the leptomeninges occurring predominantly in the posterior fossa or the upper spinal cord in adults. It shows characteristic cytologic features with isomorphic epitheliod or spindle-shaped cells, often with prominent nucleoli and a variable content of intracytoplasmic melanin. It usually lacks signs of malignancy such as high mitotic rate, necroses or infiltrative growth and shows a low labeling index in proliferation marker studies. Its immunohistological profile with S-100 protein-, vimentin- and HMB-45-positive tumour cells is similar to that of (primary or metastatic) malignant melanoma. This differential diagnosis is crucial because of the totally different therapeutic and prognostic implications. Therefore, everyone dealing with surgical neuropathology should be familiar with the rare, but clinically important diagnosis of meningeal melanocytoma.

Abstract
A 37-year-old man exhibited a suprasellar tumor which histologically proved to be a myxopapillary ependymoma. Since these gliomas are virtually restricted to the cauda equina region, magnetic resonance imaging (MRI) was performed which revealed multiple spinal tumors. The present case seems to be the first report on spontaneous intracranial seeding of a spinal myxopapillary ependymoma.

Abstract
Acute inflammatory polyradiculitis represents an uncommon peripheral nerve complication during HIV infection. The case of an HIV-seropositive patient who was admitted to hospital for a cauda equina syndrome is reported. Despite early application of anticytomegalic medication, a cytomegalovrirus (CMV) infection spread out to the central nervous system (CNS), causing the patient's death. A post-mortem examination confirmed the diagnosis of CMV-encephalomyelomeningoradiculitis. To the authors' knowledge, such a progress of a CMV-related polyradiculitis to an encephalomyelomeningoradiculitis has not yet been described. The clinical features of this case will aid in the recognition of CMV-related neurological complications, and may permit earlier and perhaps more successful treatment.

Abstract
We report 14 biopsy cases of granular cell tumours (GCT) of the central nervous system (CNS) outside the pituitary gland. In six cases the granular cells determined the morphology (actual GCT), the other eight consisted of different CNS tumours with a varying granular cell component. Pronounced immunoreactivity for ubiquitin and alpha-1-antichymotrypsin could be found in all investigated tumours, while GFAP, neuron specific enolase, von Willebrand factor, vimentin, S-100 protein, alpha-1-antitrypsin, actin, and the neurofilaments 68 kDa and 160 kDa showed mostly weak positivity in some cases. Four out of eight GCT showed no immunoreactivity for MIB1; the other four cases had a proliferation index between 0.5% and 15%. Six out of nine cases were positive for p53. We consider granular cells to originate from different cell types. Thus, although morphologically identical, GCT are actually biologically heterogeneous. GCT of the CNS may represent gliomas of mostly astrocytic origin with a metabolically induced transformation of some tumour cells into granular cells.

Abstract
Histological and immunohistochemical findings in 20 cases of frontotemporal dementias-8 cases of dementia of frontal lobe type (DFT), 7 cases of Pick's disease (PD), and 5 cases of motor neuron disease with dementia (MND/D)-are presented. Common features of all three syndromes were: frontotemporal atrophy, involvement of subcortical nuclei, and swollen chromatolytic cells. Ubiquitin (Ub)-positive and tau-negative inclusions in cortical, hippocampal, and motor neurons were found in MND/D and DFT cases, suggesting a common pathogenesis of MND/D and DFT. MND/D showed the same cytoskeletal alterations in motor nuclei as MND without dementia: Bunina bodies and skein-like, Ub-positive inclusions. DFT differed from PD in the preponderance of histopathological changes in upper cortical layers, the sparseness of chromatolytic cells, and the absence of tau-positive Pick bodies (PBs). There were, however, two transitional cases showing Pick-type histology but no PBs, thus linking DFT and PD. PBs expressed chromogranin B and secretoneurin strongly, but chromogranin A only weakly. They were negative for the 70-kDa heat-shock protein, metallothionein, and glutathione-S-transferase.

Abstract
The biological behaviour of meningeal haemangiopericytomas was retrospectively studied using immunohistochemical staining with MIB1, a monoclonal antibody against the Ki-67 antigen, a nuclear protein related to cell proliferation. Paraffin-embedded material from 62 tumours from 40 patients were investigated. The proliferating compartment of the tumours was estimated by evaluating the MIB1 staining index, i.e. the percentage of MIB1 positive nuclei in at least 1000 counted tumour cells in representative areas. The staining index ranged from 1.24% to 39.01%. Statistical analysis revealed no significant correlation between the staining index and recurrence-free survival (chi 2 = 0.3922, P = 0.5311). Long-term observation (> 100 months), however, revealed a tendency to longer survival in the group with a staining index less than 5%. According to our results, the MIB1 staining index does not contribute to the accuracy of predicting the clinical outcome of meningeal haemangiopericytomas.

Abstract
Multiple system atrophy (MSA) is a neurodegenerative disorder that encompasses different clinicopathological syndromes, either occurring alone or with a variable degree of overlap. Oligodendroglial, intracytoplasmic argyrophilic and ubiquitin-reactive inclusions are regarded as a histologic hallmark. We examined the distribution and specificity of these ubiquitin-reactive inclusions (UBRI) in 20 cases of MSA (7 cases of sporadic adult olivoponto-cerebellar atrophy [OPCA], 1 case of hereditary adult OPCA, 4 cases of infantile OPCA, 2 cases of Shy-Drager-Syndrome [SDS], 4 cases of striatonigral degeneration [SND] and 2 cases of non-classified atrophy of multiple systems) and 93 control cases with various disorders. Antibodies were used against ubiquitin, PGP 9.5, TAU-protein, glutathion-S-transferase (GST) and metallothionein (MT). Oligodendroglial UBRI were detected in all but 2 cases of sporadic adult MSA and 3 controls, whereas they were absent in hereditary and infantile OPCA. They could also be recognized with Gallyas stain and anti-TAU. Immunopositivity was also seen with GST (11 cases), PGP 9.5 (4 cases) and MT (1 case). Distribution of oligodendroglial UBRI, although not showing topographical linkage to neuronal degeneration in all cases, does not seem to occur in a haphazard pattern.

Abstract
We report a sporadic case of giant axonal neuropathy (GAN) starting in a 5-year-old boy with gait disturbance. At the age of 10 years he showed signs of a sensomotoric polyneuropathy and central neurological symptoms: intention tremor, nystagmus and visual disturbance. The boy also had curly hair. Sural nerve biopsy showed many giant axons with accumulation of microfilaments, which were also found in cytoplasma of Schwann cells, endothelial cells and fibrocytes. Similar changes were detected in endothelial cells of a muscle biopsy, which additionally displayed neurogenic atrophy and target fibers. Immunohistochemically, desmin, vimentin, heat shock protein 70, and ubiquitin were not detectable in giant axons, which, however, contained neurofilament protein 68, 200 and beta-tubulin. Our case shows that careful ultrastructural examination of a muscle biopsy may point to the diagnosis of GAN.

Abstract
Nemaline myopathy belongs to the group of congenital non-progressive myopathies; however, in rare cases death occurs in early infancy. We report two cases of rapidly fatal nemaline myopathy. The first patient, who died at the age of 26 months, showed atrophy of type 1 fibers containing numerous rods in biopsy sections. Biopsy of the second patient, who had died at the age of 5 months, revealed severe maturational arrest and myopathy, but rods were so rare that diagnosis could only be made at the ultrastructural level. Autopsy of both patients showed that atrophy of type 1 fibers and maturational arrest had disappeared in the very same muscles; rods had moved to a central position in the first and significantly increased in number in the second case. Diaphragma muscles contained abundant amounts of rods in both cases. The cardiac musculature showed a few rods only in the first patient, who had developed heart insufficiency 11 months prior to death. Immunohistochemical analysis showed that rods did not contain desmin or ubiquitin.

Abstract
The results of immunohistochemical detection of p53 protein in a large variety of CNS neoplasms with the polyclonal antiserum CM1 are presented. Immunoreactivity in at least several cells were regularly found in astrocytic neoplasms including glioblastomas; it was also frequent in medulloblastomas and oligodendrogliomas and could be found in more than 50% of acoustic schwannomas and esthesioneuroblastomas. Meningiomas also showed several immunoreactive cells in about 40% of the cases. Certain neuronal/neuronal-glial tumours (such as central neurocytomas, dysembryoplastic neuroepithelial tumours, gangliocytomas, dysplastic gangliocytomas of the cerebellum etc.) were consistently negative, whereas gangliogliomas (with the exception of the regularly positive desmoplastic gangliogliomas) very rarely displayed immunoreactive glial cells. Positive findings, however, seem to be more frequent in anaplastic gangliogliomas where they may be of prognostic significance. The same may be valid in ependymomas. The underlying mechanism for p53 immunopositivity, however, can be very heterogeneous and possibly even contrary (either accumulation of inactive mutant protein or detection of active wild-type protein), therefore isolated immunohistochemical findings call for very cautious interpretation.

Abstract
Involvement of Onuf's nucleus (ON) in 28 cases of amyotrophic lateral sclerosis/motor neuron disease (MND/ALS) with different clinical syndromes is reported. Although significant neuronal loss was absent, all cytoskeletal abnormalities typical of alpha-motor neurons in MND/ALS were found in ON. Spheroids were detected in 53.5% of cases; 0.6-4.5% of ON neurons contained Bunina bodies, which were present in 42.8% of cases. Ubiquitin-reactive inclusions (UBRI) of filamentous and hyaline type were found in 57.1% of cases and in 1.2-10.7% of ON neurons. Cases with pyramidal tract involvement (ALS) were involved by UBRI in 76.5%, whereas cases with progressive spinal muscular atrophy revealed the same inclusions in only 27.2%. No similar inclusions were present in sacral parasympathetic intermediolateral nucleus. It can be concluded, therefore, that ON belongs to the somatic motor system and is principally vulnerable to MND/ALS, albeit to a lower degree.

Abstract
A case of dysembryoplastic neuroepithelial tumour of the cerebellum occurring in a 28-year-old woman is presented. The lesion extended from the cortex of the inferior vermis upwards into the white matter. Histologically, it exhibited areas of microcystic cerebellar astrocytoma and glial regions with hamartomatous blood vessels as well as areas with oligodendrocyte-like cells (OLC) with a delicate, fibrillary stroma lying in a mucinous, often microcystic matrix. The OLC showed prominent rosette formation and immunohistochemical features suggesting neuronal, i.e. granule cell, differentiation.

Abstract
Two pineal parenchymal tumors are presented, arising in a 54-year-old man and a 72-year-old woman; respectively. They showed isomorphic, cellular areas of small cells, often with characteristic pineocytomatous rosettes, and of medium-sized cells, as well as less cellular regions with highly pleomorphic, often ganglioid large cells. Immunohistochemistry disclosed extensive neuronal differentiation. There was intense positivity for neurofilament protein and microtubule-associated protein 2 in the pleomorphic areas and more variable expression in the isomorphic regions. Diffuse synaptophysin positivity was seen, accentuated along the borders of pleomorphic cells and in the rosettes, as well as diffuse interstitial and/or cytoplasmic expression of neuron-specific enolase, PGP 9.5 and tau. beta-Tubulin III was detected in most cells and slight positivity was found in the rosettes. Expression of glial fibrillary acidic protein, however, was restricted to resident astrocytes and an interstitial network of processes. These neuronally differentiated pleomorphic pineocytomas underline the broad histomorphological spectrum of pineal parenchymal tumors.

Abstract
Five cases of intravascular lymphomatosis (IVL) are reported. Diffuse or focal cerebral signs suggestive of vascular disease occurred in four cases, but case 5 presented with symptoms similar to Creutzfeld-Jakob disease. Clinical course ranged from two to eight months and diagnosis was made in all cases by autopsy. Neoplastic lymphoid cells mainly lodged in lumina of small vessels in many organs, but infarction was confined to the CNS. Some extravascular tumor cells were regularly seen. All cases corresponded to high-grade Non-Hodgkin lymphomas of B-cell type and displayed high proliferation indices. Different from findings in primary cerebral and nodal lymphomas, neither p53 nor bcl-2 oncoproteins were detectable. Absence of EBV genome and EBV latent membrane protein from IVL was demonstrated for the first time.

Abstract
This report presents a case of infantile multiple system atrophy with probably autosomal recessive inheritance. The female patient developed generalized muscular hypotonia, myoclonias and tonic-clonic seizures at the age of 8 months, followed by gradual development of choreoathetotic hyperkinesia and increasing psychomotor retardation. Metabolic disease was ruled out and the child died of aspiration pneumonia at the age of 5 years. General autopsy was unremarkable, but neuropathological examination showed degeneration of cerebellum, inferior olives, medial thalamus, Clarke's nucleus, anterior horn cells, corticospinal, spinocerebellar tracts, and posterior columns. Immunohistochemically many neurons contained intranuclear and intracytoplasmic ubiquitin-positive inclusions, which did not contain neurofilament or tau epitopes and ultra-structurally consisted of granulofilamentous material. We tentatively classify this case as a form of infantile multiple system atrophy linked to neuronal intranuclear hyaline inclusion disease.

Abstract
The neuropathological findings at autopsy in four cases of type I and three of type II lissencephaly are presented. Type I lissencephaly is characterized by agyriapachygyria with a markedly thickened cerebral cortex with four coarse histological layers. The normally myelinated white matter, often with neuronal heterotopias, is very narrow, and the gray-to-white matter ratio is inverted (about 4:1); there are no white-gray interdigitations. Claustrum and capsula extrema are absent. Ventricular dilatation is present, especially of the occipital horns. In the hypoplastic brain stem large olivary heterotopias can often be observed. Severe cerebellar malformations, obstructive hydrocephalus, severe eye abnormalities, and congenital muscular dystrophy are not seen. Clinically, type I lissencephaly presents as "isolated lissencephaly sequence" or as "Miller-Dieker syndrome" with characteristic facial dysmorphism. The long survival of 20 years achieved by one of our patients is very uncommon. Type II lissencephaly is characterized by widespread agyria. Usually, obstructive hydrocephalus is present with a thin cerebral mantle showing a slightly thickened cortex and a narrow, hypomyelinated white matter often with neuronal heterotopias (gray-to-white matter ratio about 1:1). The border between gray and white matter is blurred. Claustrum and capsula extrema are absent. Histologically, the cortex appears disorganized without layering; widespread leptomeningeal gliomesenchymal proliferations and glioneuronal heterotopias are present.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Ocular symptoms are frequently observed in Walker-Warburg (WWS) and associated syndromes. The majority of patients present with malformations of the anterior segment and severe retinal dysplasia. We report on the findings in a female patient with WWS who died at the age of 9 months. Major ocular findings were: severe iridocorneal malformation, a membrane-like structure of the lens and funnel-shaped retinal dysplasia. The retina presented various grades of differentiation with rosettes and atypical sequences of cells, e.g. ganglion cells intermingled between granular layers. The anterior part of the retina presented as a primitive homogeneous layer with a cell-free space that might be interpreted as the primary optic ventricle. This finding suggests that we are dealing with a primary dysplastic non-attachment rather than a real detachment of the retina in WWS. The malformation of the anterior segment was not typical of the Peters' anomaly, as usually described in WWS, but of Rieger's syndrome.
