It was then added to the 4th edition of the World Health Organization (WHO) of head and neck tumors in 2012. BSNS has been described as a rare low-grade sarcoma arising in the upper sinonasal tract. It is believed that in the past, BSNS was, likely, previously diagnosed as other low-grade or benign malignancies. Fibrosarcoma, leiomyosarcoma, and peripheral nerve sheath tumors, all fall within the differential diagnosis of BSNS. However, BSNS is unlike other mesenchymal sinonasal tumors, as it displays both neural and myogenic differentiation. BSNS has thus far been recognized in only a hand full of case reports, all of which have reported similar morphologic features of a low-grade soft tissue tumor with neural involvement arising from the nasal cavity or ethmoid air cells in middle aged individuals. In fact, being low-grade sarcoma became such a hallmark characteristic of this tumor that it even received the name low-grade sinonasal sarcoma with neural and myogenic features or LGSSNMF. <b>Case Presentation</b>  We present, however, for the first time, a high-grade differentiation of BSNS in an otherwise healthy 72-year-old female. The patient was referred from an outside ENT (ear, nose, and throat) after pathology from a presumed polypectomy returned positive for a BSNS. Initial imaging revealed erosion through the bilateral lamina papyracea, anterior cranial fossa floor, and posterior table of the frontal sinus. She then underwent a combined endoscopic and bicoronal open approach for resection of the skull base lesion that was found to encompass the entirety of the sinonasal cavities bilaterally. Postoperatively, the patient underwent significant complications including infection of the pericranial flap, pneumocephalus, and eventually death. <b>Discussion</b>  As BSNS is a fairly new entity, currently there has only been four case series conducted, each identifying features of a low-grade sarcoma with both myogenic and neural differentiation. Histologically, BSNS has monophasic spindle cells with uniform, elongated nuclei with scant cytoplasm between benign proliferations of surface-type respiratory epithelium, with a low mitotic rate. Our case, however, revealed pleomorphic hyperchromatic cells with high mitotic activity and necrosis with invasion of bone, staging it as high grade. Immunohistochemistry also differed from the previously reported standards. This case describes a new category for BSNS which may change the differential diagnosis, management, and surgical recommendations that are currently utilized for this skull base neoplasm.</p>","PeriodicalId":44256,"journal":{"name":"Journal of Neurological Surgery Reports","volume":" ","pages":"e105-e109"},"PeriodicalIF":0.5,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/9d/8c/10-1055-s-0042-1755599.PMC9470382.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40361868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evolution of a Fluorescence-Positive Diffuse Astrocytoma: A Case Report.","authors":"Jose E Valerio,&nbsp;Sebastian Ochoa,&nbsp;Sandra Alvarez,&nbsp;Matteo Borro,&nbsp;Andres M Alvarez-Pinzon","doi":"10.1055/a-1858-7628","DOIUrl":"https://doi.org/10.1055/a-1858-7628","url":null,"abstract":"<p><p><b>Introduction</b>  In 2017, the U.S. Food and Drug Administration (FDA) approved 5-aminolevulinic acid (5-ALA) as an intraoperative optical imaging agent in patients with suspected high-grade gliomas (HGGs). However, the application of 5-ALA for low-grade gliomas is still less accepted. Astrocytoma, isocitrate dehydrogenase (IDH) mutant tumors are diffuse infiltrating astrocytic tumors where there is no identifiable border between the tumor and normal brain tissue, even though the borders may appear relatively well-marginated on imaging. Generally, it is considered that 5-ALA cannot pass through a normal blood-brain barrier (BBB). Thus, 5-ALA fluorescence may mean disruption of BBB in grade II glioma. <b>Case Report</b>  A 74-year-old male patient was diagnosed with a right parietal lesion suggestive of a low-grade brain tumor in a surgical resection using 5-ALA, which led to the detection of tiny fluorescence spots during the surgery. The frozen section was consistent with diffuse astrocytoma, IDH-wildtype (World Health Organization [WHO] grade II). The patient's postoperative magnetic resonance imaging (MRI) showed complete resection. Eight months after surgery, he began experiencing symptoms again and was admitted with a brain MRI finding consistent with recurrent infiltrating astrocytomas. This required reoperation of the brain tumor resection with 5-ALA. Unlike the first surgery, they observed a high fluorescence intensity; the pathological finding was glioblastoma, IDH-wildtype (WHO grade IV). Postsurgical brain MRI showed total resection of the tumor. The patient was discharged 4 weeks after surgery and continued with specialized clinical follow-up. <b>Conclusion</b>  The use of 5-ALA continues to be a great contributor to the improvement in complete resection of primary brain tumors, especially HGG. Besides, fluorescence is increasingly approaching its use as a prognostic tool for aggressive clinical course, regardless of the initial grade of the tumor. This case report is an effort to expand knowledge for potentially using 5-ALA to help prognosticate brain tumors. Nevertheless, more clinical prospective studies must be conducted.</p>","PeriodicalId":44256,"journal":{"name":"Journal of Neurological Surgery Reports","volume":" ","pages":"e95-e99"},"PeriodicalIF":0.5,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/cc/e8/10-1055-a-1858-7628.PMC9411034.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33442356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
