They are mostly found in infratentorial structures such as the cerebellum and in midline cerebral structures such as the optic nerve, hypothalamus, and brain stem. The present study aimed to list the main characteristics about this tumor, to better understand the diagnosis and treatment of these patients, and was conducted on search of the published studies available in NCBI, PubMed, MEDLINE, Scielo, and Google Scholar. It was possible to define the main histologic findings observed in these cases, such as mitoses, necrosis, and Rosenthal fibers. We described the locations usually most affected by tumor development, and this was associated with the most frequent clinical features. The comparison between the molecular diagnostic methods showed great use of fluorescent in situ hybridization, polymerase chain reaction (PCR), and reverse transcriptase\u2013PCR, important techniques for the detection of BRAF V600E mutation and BRAF-KIAA1549 fusion, characteristic molecular alterations in pilocytic astrocytomas.<\/jats:p>","DOI":"10.1177\/0883073820937225","type":"journal-article","created":{"date-parts":[[2020,7,21]],"date-time":"2020-07-21T01:37:16Z","timestamp":1595295436000},"page":"852-858","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":66,"title":["Pilocytic Astrocytoma: A Review of General, Clinical, and Molecular Characteristics"],"prefix":"10.1177","volume":"35","author":[{"given":"D\u00e9bora","family":"Salles","sequence":"first","affiliation":[{"name":"Department of Pathology, Universidade Federal de S\u00e3o Paulo, Escola Paulista de Medicina, S\u00e3o Paulo, Brazil"},{"name":"Laboratory of Molecular and Experimental Pathology, Universidade Federal de S\u00e3o Paulo, Escola Paulista de Medicina, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriela","family":"Laviola","sequence":"additional","affiliation":[{"name":"Department of Pathology, Universidade Federal de S\u00e3o Paulo, Escola Paulista de Medicina, S\u00e3o Paulo, Brazil"},{"name":"Laboratory of Molecular and Experimental Pathology, Universidade Federal de S\u00e3o Paulo, Escola Paulista de Medicina, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0397-6135","authenticated-orcid":false,"given":"Andr\u00e9a Cristina de Moraes","family":"Malinverni","sequence":"additional","affiliation":[{"name":"Department of Pathology, Universidade Federal de S\u00e3o Paulo, Escola Paulista de Medicina, S\u00e3o Paulo, Brazil"},{"name":"Laboratory of Molecular and Experimental Pathology, Universidade Federal de S\u00e3o Paulo, Escola Paulista de Medicina, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jo\u00e3o Norberto","family":"St\u00e1vale","sequence":"additional","affiliation":[{"name":"Department of Pathology, Universidade Federal de S\u00e3o Paulo, Escola Paulista de Medicina, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,7,20]]},"reference":[{"key":"bibr1-0883073820937225","doi-asserted-by":"publisher","DOI":"10.1093\/neuonc\/nox158"},{"key":"bibr2-0883073820937225","doi-asserted-by":"publisher","DOI":"10.1093\/jnen\/nly116"},{"key":"bibr3-0883073820937225","unstructured":"Louis D, Ohgaki H, Wiestler O, Webster K.
