The majority occur in lymph nodes but around 30% can occur extranodally including in the spleen, lungs, head and neck and liver. We present an unusual case of an FDCS of the parotid gland in a 51-year-old woman with a history of Hodgkin\u2019s lymphoma treated with combination chemotherapy and modified mantle radiotherapy. Only four cases of an intraparotid FDCS have been previously reported. The patient underwent a superficial parotidectomy and level 2\/3 neck dissection. A diagnosis of an intraparotid FDCS (25\u2009mm) with no nodal disease was made. Given this patient\u2019s history of radiotherapy 20 years previously, we speculate the possibility of postradiation sarcoma.<\/jats:p>","DOI":"10.1136\/bcr-2018-224301","type":"journal-article","created":{"date-parts":[[2018,5,30]],"date-time":"2018-05-30T07:36:16Z","timestamp":1527665776000},"page":"bcr-2018-224301","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":8,"title":["Follicular dendritic cell sarcoma presenting as a painless lump in the parotid"],"prefix":"10.1136","volume":"2018","author":[{"given":"Emma","family":"McClelland","sequence":"first","affiliation":[{"name":"Department of Otolaryngology, Royal Surrey County Hospital NHS Foundation Trust, Guildford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony","family":"Bashyam","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Royal Surrey County Hospital NHS Foundation Trust, Guildford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Derbyshire","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Royal Surrey County Hospital NHS Foundation Trust, Guildford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvana","family":"Di Palma","sequence":"additional","affiliation":[{"name":"Department of Histopathology, Royal Surrey County Hospital NHS Foundation Trust, Guildford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,5,30]]},"reference":[{"key":"2025082800264191000_2018.may29_1.bcr-2018-224301.1","doi-asserted-by":"crossref","first-page":"225","DOI":"10.3389\/fimmu.2016.00225","article-title":"How Follicular Dendritic Cells Shape the B-Cell Antigenome","volume":"7","author":"Kranich","year":"2016","journal-title":"Front Immunol"},{"key":"2025082800264191000_2018.may29_1.bcr-2018-224301.2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0142(19970115)79:2<294::AID-CNCR13>3.0.CO;2-W"},{"key":"2025082800264191000_2018.may29_1.bcr-2018-224301.3","doi-asserted-by":"crossref","first-page":"2375","DOI":"10.1182\/blood-2016-01-643569","article-title":"revision of the World Health Organisation (WHO) classification of lymphoid neoplasms","volume":"2016","author":"Swerdlow","year":"2016","journal-title":"Blood"},{"key":"2025082800264191000_2018.may29_1.bcr-2018-224301.4","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/103.1.90"},{"key":"2025082800264191000_2018.may29_1.bcr-2018-224301.5","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0347(199905)21:3<273::AID-HED14>3.0.CO;2-Q"},{"key":"2025082800264191000_2018.may29_1.bcr-2018-224301.6","doi-asserted-by":"publisher","DOI":"10.1038\/modpathol.3880489"},{"key":"2025082800264191000_2018.may29_1.bcr-2018-224301.7","doi-asserted-by":"crossref","first-page":"2062","DOI":"10.3892\/ol.2016.4826","article-title":"Li Shen, Hongzhi Dai and Yiding Ji Follicular dendritic cell sarcoma of the spleen: A case report and review of the literature","volume":"12","author":"Wang","year":"2016","journal-title":"Oncol Lett"},{"key":"2025082800264191000_2018.may29_1.bcr-2018-224301.8","doi-asserted-by":"crossref","unstructured":"Sahay A , Bal M , Patil A , et al .
