It most commonly arises from lymph nodes, but may originate from a variety of extranodal sites. FDCS of appendix is exceptionally rare, and only a single case has been reported. Herein, we describe the clincopathological features of a case of FDCS originating from appendix with emphasis on being able to recognize this rare neoplasm in the context of the differential diagnosis of more common intraabdominal spindle cell tumors.<\/jats:p>","DOI":"10.1177\/1066896916651494","type":"journal-article","created":{"date-parts":[[2016,5,25]],"date-time":"2016-05-25T20:54:04Z","timestamp":1464209644000},"page":"631-634","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Follicular Dendritic Cell Sarcoma of Appendix Presenting as Acute Appendicitis"],"prefix":"10.1177","volume":"24","author":[{"given":"Arsalan","family":"Ahmed","sequence":"first","affiliation":[{"name":"Aga Khan University Hospital, Karachi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nasir","family":"Ud Din","sequence":"additional","affiliation":[{"name":"Aga Khan University Hospital, Karachi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdur Rehman","family":"Alvi","sequence":"additional","affiliation":[{"name":"Aga Khan University Hospital, Karachi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian P.","family":"Rubin","sequence":"additional","affiliation":[{"name":"Cleveland Clinic, Cleveland, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,7,28]]},"reference":[{"key":"bibr1-1066896916651494","unstructured":"Swerdlow SH, Campo E, Harris NE, eds.
