Brain MRI showed an approximately 6.5\u00a0\u00d7\u00a05.3\u00a0cm\u2010sized huge heterogeneous enhancing mass located in the corpus callosum, extending into the lateral ventricle. Open biopsy showed that the lesion consisted of lymphoplasmacytes and plump histiocytes with rhabdoid morphology, which were stained with S\u2010100 protein, CD68 (KP1) and negative for CD1a. Histiocytic tumor was initially diagnosed. Chemotherapy using methotrexate, 6\u2010mercaptopurine, vinblastine, interferon\u2010alpha and dexamethasone was performed. After 5\u00a0months, partial removal was done. Microscopically, plump and bizarre tumor cells as well as rhabdoid features were found. Occasional spindle cells and necrosis were also found. These cells were positive for CD163, CD68, lysozyme, CD4, INI\u20101 and BRG1. BRAF V600E mutation was detected. The lesion was finally diagnosed as histiocytic sarcoma. Radiotherapy (6000 cGy in 30 fractions) was done. Both cerebral and extracerebral histiocytic sarcomas have long been diagnosed by unclarified criteria; its rarity as well as previously unclarified criteria can easily lead to a misinterpretation. Histiocytic sarcoma of the CNS is exceptionally rare in children, associated with an exceptionally poor prognosis. To date, only seven cases of pediatric cerebral histiocytic sarcomas have been reported. The present case is the first pediatric case showing BRAF V600E\u2010mutated intracerebral histiocytic sarcoma.<\/jats:p>","DOI":"10.1111\/neup.12396","type":"journal-article","created":{"date-parts":[[2017,7,27]],"date-time":"2017-07-27T05:02:39Z","timestamp":1501131759000},"page":"560-568","source":"Crossref","is-referenced-by-count":11,"title":["Pediatric
