Autopsies were performed in both cases after an informed consent. A detailed sampling of the brain including extracranial organs was conducted. Immunohistochemistry and electron microscopy was also performed to confirm the presence of viruses.Results: Besides evidence of cystic encephalomalacia observed in both cases, the brain in case 1 revealed cytomegalovirus (CMV) ventriculoencephalitis accompanied by an exuberant gemistocytic response in the entire white matter. Nuclei of gemistocytes were loaded with several CMV nuclear inclusions, which was confirmed by immunohistochemistry. Case 2 demonstrated features of measles inclusion body encephalitis with several viral inclusions within neurons and astrocytes. Rare giant cells were also seen. Measles virus was confirmed on immunohistochemistry and electron microscopy. Plausibly, there was paucity of microglial nodules in both cases. Superadded bacterial pneumonia with diffuse alveolar damage was also seen in both cases.Conclusion: These cases add to the spectrum of unusual histological features of viral encephalitis seen in patients with underlying primary immunodeficiency diseases.","PeriodicalId":55251,"journal":{"name":"Clinical Neuropathology","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10754872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is variable in morphology, but the astroblastic pseudorosettes and vascular hyalinization are the most important features. Most astroblastomas occur in the cerebral hemisphere. We report a recurrent high-grade astroblastoma with MN1-BEND2 fusion in the spinal cord. Two lesions were found in the T5-7 level and T12-L1 level, and they were well defined in images. Rhabdoid and signet-ring-like cells were observed. It may be classified as a high-grade tumor due to cellularity, high mitotic count, and pleomorphism. The tumor cells were diffusely positive for GFAP, Olig-2, and S-100 protein. We found the MN1 arrangement and the loss of chromosome 1p by FISH, and further validated the BEN domain containing 2 genes (BEND2), which is the fusion partner of meningioma 1 gene (MN1), by next-generation sequencing (NGS) and Sanger sequencing. The MN1 mutation is crucial in the diagnosis and prognosis of rare astroblastoma. The spinal cord astroblastoma may have a high recurrence rate because of the residual lesion at the unique location and higher grade; the connection with the gene mutation is unclear. Regular follow-up is necessary. Further study and more cases are needed to establish evidence for diagnosis, prognosis, and treatment of astroblastoma with molecular characteristics.","PeriodicalId":55251,"journal":{"name":"Clinical Neuropathology","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10751587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It arises from midline structures in the brain and spinal cord. Recently, the presence of H3 K27M mutation is described in most cases. Extra-cranial osseous metastasis is rarely encountered.Case presentation: We present an interesting case of DMG with bone metastasis at presentation in a 19-year-old male. In addition, a literature review on similar cases is presented.Discussion: DMG mostly affects children and young adults. It has a broad spectrum of phenotypes, shows diffuse growth pattern, midline location, and is frequently H3 K27M-mutant. Radiotherapy remains the mainstay of treatment that might improve overall survival. Metastasis outside the CNS remains a rare occurrence, especially at presentation, and constitute a diagnostic challenge.Conclusion: Bone is one of the most common sites for metastasis of primary CNS tumors, which would severely impact prognosis. Oncologists, radiologists, and pathologists should keep an index of suspicion when encountering bone metastasis in the presence of a CNS midline tumor, so that timely diagnosis and management can be rendered.","PeriodicalId":55251,"journal":{"name":"Clinical Neuropathology","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40410286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
