Abstract
C11orf95-RELA fusion or, less frequently, YAP1 fusion is recurrently detected in most cases of supratentorial ependymoma. Other fusions have rarely been reported in some cases of supratentorial ependymoma, and little is known about their pathological or clinical features. Here, we present a case of supratentorial ependymoma with unusual pathological findings and C11orf95-MAML2 fusion. A 23-year-old man was admitted to our hospital because of headache and vomiting. Magnetic resonance imaging revealed a cystic lesion in the right frontal lobe, and gross total resection of the tumor was performed. Pathologically, the tumor was mainly composed of typical ependymal lesions with perivascular pseudorosettes and contained some atypical lesions, with granular and ganglion cell features. The tumor was diagnosed as anaplastic ependymoma, which was classified as grade III on the World Health Organization scale, and found to be RELA fusion-positive in the DNA methylation analysis. However, the tumor was negative for C11orf95-RELA fusion, and RNA sequencing detected C11orf95-MAML2 fusion. The patient has not received adjuvant therapy and has remained alive without any evidence of disease for 30 months, suggesting that the prognosis might be better than that of typical C11orf95-RELA fusion-positive ependymoma.

Abstract
Background: Cavernous sinus tumours comprise 0.1-0.2% of all intracranial tumours, and are most commonly meningiomas or schwannomas. Central nervous system and cranial nerve granular cell tumours (GCTs) are extremely rare. We report the tenth case of a GCT arising from a cranial nerve, and the second case reported in a cavernous sinus location, and review the literature. Clinical presentation: A 67-year-old man presented with right sided trigeminal neuralgia. Imaging findings suggested a trigeminal schwannoma and he was treated with CyberKnife radiosurgery. Over a period of 41 months follow up, there was a progression in both symptoms and imaging findings, requiring debulking surgery. Histopathology identified a GCT. Conclusions: This is the first case of a cranial nerve GCT treated with stereotactic radiosurgery. Trigeminal nerve GCTs are a rare differential in cases of presumed schwannomas.

Abstract
AIMS Granular-cell astrocytomas (GCAs) are morphologically characterized by a prominent component of granular periodic acid-Schiff-positive cells, and show increased aggressiveness as compared with 'ordinary' astrocytomas. The aim of this study was to investigate, in a small series of three GCAs, the expression of mesenchymal/radioresistance-associated biomarkers [such as chitinase-3-like protein 1 (YKL-40), hepatocyte growth factor receptor (c-Met), and caveolin 1 (Cav1)] that could contribute to the poor outcome associated with this glioma subgroup. METHODS AND RESULTS Our results show that GCAs, according to the new molecular glioma classifications, consistently show a prognostically negative molecular trait (IDH1wt-ATRX noloss-1p/19q nocodeletion). Furthermore, GCAs significantly differed from a control series of 33 'conventional' astrocytomas, because of diffuse and strong immunohistochemical coexpression of YKL-40, c-Met, and Cav1. CONCLUSIONS Our findings show that specific morphological traits, such as a granular-cell component, could represent useful features in guiding the search for prognostic and predictive biomarkers that could eventually be therapy-targetable (e.g. Met inhibitors aimed at reducing radioresistance).

Orbital granular cell tumours: clinical and pathologic characteristics of six cases and literature review. Eye (Lond) 2016; 30:529-37.

Abstract
OBJECTIVE To retrospectively assess the clinicopathological characteristics of orbital granular cell tumours (GCTs). METHODS A non-comparative review of the clinical characteristics, imaging, histopathological features, management, and prognosis of five cases of benign GCT and one case of malignant GCT (MGCT) was conducted, along with a review of the English language literature. RESULTS Among the six cases, four tumours were adherent to the extraocular muscle (EOM), and three tumours to the optic nerve (ON). Morphologic examinations revealed polygonal cells containing periodic-acid-Schiff-positive eosinophilic granules. All tumours (100%) were positive for VIM and NSE, five (83.3%) tumours were positive for S-100, and three (50%) tumours were positive for CD68. The follow-up examination of the MGCT witnessed recurrence and brain metastasis despite several thorough resections, but the patient remained alive; the follow-up examination of the four benign GCTs that had received incomplete excision revealed recurrence in one patient and dramatic shrinkage of the residual tumour in another; there was no recurrence in the other two patients. CONCLUSIONS GCT should be considered in the differential diagnosis of orbital tumours, which may affect EOMs and ON. The natural course of GCT can include tumour progression, stability, or spontaneous regression. To avoid recurrence, complete resection is recommended for orbital GCT. To the best of our knowledge, primary orbital MGCT is reported for the first time.

Abstract
We report here a rare case of granular cell astrocytoma. A 75-year-old man was admitted to Inha University Hospital with a three-month history of language deterioration. In a magnetic resonance imaging, a 6.5 cm-sized heterogeneous enhancing mass was seen in both the frontal lobes and the anterior genu of the corpus callosum. A stereotactic biopsy was performed. The tumor was composed of large and small round cells with abundant intracytoplasmic granules. The nuclei were bland, round to oval, and often eccentrically located. The cytoplasm of the tumor cells was positive for glial fibrillary acidic protein and S-100 protein.

Abstract
We treated a 56-year-old woman who had a right temporal lobe tumor found by chance after a traffic accident. MRI confirmed a heterogeneously enhanced tumor in the temporal lobe with large peritumoral edema extending to the superior parietal lobe. The patient underwent tumor resection. The tumor consisted largely of distinct cells with discrete borders and granular cytoplasm. In granular cells, the accumulation of PAS-positive granules was observed. Immunohistochemical analysis demonstrated positive staining for GFAP, S-100, and oligodendrocyte transcription factor 2 and negative staining for synaptophysin. CD68 was negative in granular cells, but positive in stromal cells. Ki-67 labeling index was quite low. The tumor was diagnosed as a granular cell astrocytoma (GCA). Postoperative radiotherapy combined with temozolomide was administered. One month after chemoradiotherapy, the tumor occurred in the parietal lobe, and a tumorectomy was performed. The tumor was composed of poorly differentiated astrocytic tumor cells with prominent microvascular proliferation and necrosis. A small number of granular cells were locally observed and the tumor was diagnosed as a glioblastoma. O6-methylguanine-DNA methyltransferase promoter methylation was detected in the GCA but not in the glioblastoma. Isocitrate dehydrogenase mutations were not detected in either tumor. Comparative genomic hybridization analysis demonstrated that no chromosomal abnormality was found in the GCA; however, a gain of chromosomes 7 and 19 and a loss of chromosomes 10 and 9p21 (CDKN2A) were found in the glioblastoma. p53 was strongly expressed in both the GCA and glioblastoma. The tumor progressed despite extensive chemotherapy, and the patient died 1 year after the initial treatment. Our immunohistochemical, genetic and chromosomal analyses indicate that the glioblastoma was transformed from the GCA.
