“Primitive polar spongioblastoma selleck products was first described by Russell and Cairns in 1947. However, the polar spongioblastoma pattern is often seen in many neuroepithelial tumors, and this category was deleted in the previous World Health Organization (WHO) classification. In 2010, Nagaishi et al. reported on a case involving a neuroepithelial

tumor with the typical histological pattern of polar spongioblastoma and suggested that this tumor might click here not be suited to any of the neuroepithelial tumors in the current WHO classification. We report on an autopsy case involving an unclassified high-grade glioma with polar spongioblastoma pattern that was very similar to the case described by Nagaishi et al. A 44-year-old man who presented with a headache exhibited a tumor of the right frontal lobe on MRI. Histological diagnosis of the tumor obtained by gross total resection was high-grade glioma, which was composed of the parallel palisading of spindle tumor cells expressing

GFAP, without microvascular proliferation (MVP) and necrosis. Conventional chemoradiotherapy was performed, but the case was complicated by cerebrospinal fluid (CSF) dissemination that resulted in multiple extraneural metastases through systemic diversionary CSF shunting. Finally, the patient died approximately 13 months after the initial treatment. Both the cerebral and Douglas pouch tumors that were obtained at autopsy were diagnosed as typical glioblastomas, and they were composed of the proliferation of atypical astrocytes with MVP and pseudopalisading necrosis without the formation of rhythmic palisading. Although Afatinib nmr the histological findings were different from that of the first operation, immunohistochemical and genetic profiles demonstrated almost the same results. This tumor was not classified as a typical glioblastoma by the initial findings, but it had the nature of a glioblastoma. These findings suggest that the tumor might be classified as a new subset of glioblastoma called glioblastoma with polar spongioblastoma pattern. “
“The effect of combustion smoke inhalation on the respiratory system is widely reported but its effects on the central nervous system remain unclear. Here, we aimed to determine the effects of smoke inhalation on the cerebellum and hippocampus which are areas vulnerable to hypoxia injury.
