Ancillary tests as well as clinico\u2010radiological correlation are often required to make an accurate diagnosis. FNA is a low\u2010cost, low\u2010infrastructure test, making it a coveted diagnostic tool, especially in low\u2010resource settings. Olfactory neuroblastoma (ONB) is a rare SRBCT encountered in both pediatric and adult patients. Awareness of the cytomorphologic and immunocytochemical features of ONB is important in the workup of a SRBCT. This case report describes the primary diagnosis of metastatic ONB on FNA cytology.<\/jats:p>","DOI":"10.1002\/dc.24868","type":"journal-article","created":{"date-parts":[[2021,9,7]],"date-time":"2021-09-07T14:59:15Z","timestamp":1631026755000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Metastatic olfactory neuroblastoma: A small round blue cell puzzle on fine\u2010needle aspiration cytology"],"prefix":"10.1002","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0525-7134","authenticated-orcid":false,"given":"Ingrid H.","family":"Penzhorn","sequence":"first","affiliation":[{"name":"Division of Anatomical Pathology, Tygerberg Hospital, National Health Laboratory Service, Faculty of Medicine and Health Sciences Stellenbosch University  Cape Town South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4422-7349","authenticated-orcid":false,"given":"Pawel T.","family":"Schubert","sequence":"additional","affiliation":[{"name":"Division of Anatomical Pathology, Tygerberg Hospital, National Health Laboratory Service, Faculty of Medicine and Health Sciences Stellenbosch University  Cape Town South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,9,7]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"crossref","first-page":"155","DOI":"10.1007\/978-3-642-20086-1","volume-title":"Quick Reference Handbook for Surgical Pathologists","author":"Rekhtman N","year":"2011"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2303.2008.00555.x"},{"issue":"3","key":"e_1_2_7_4_1","first-page":"309","article-title":"Fine\u2010needle aspiration (FNA) cytology diagnosis of small round cell tumors: value and limitations","volume":"47","author":"Das DK","year":"2004","journal-title":"Indian J Pathol Microbiol"},{"issue":"3","key":"e_1_2_7_5_1","first-page":"299","article-title":"Cytologic diagnosis of olfactory neuroblastoma.
