Less than 100 cases of FDCS were in the gastrointestinal tract, with only four cases described in the stomach, none of them diagnosed on fine needle aspiration (FNA) cytology. We report here the first case of FDCS of the stomach diagnosed on FNA. Our patient is a 31\u2010year\u2010old male who presented with several years history of intermittent abdominal pain prompting occasional emergency\u2010room visits. Imaging showed a 10.6\u2009cm mass arising from the stomach, concerning for gastrointestinal stromal tumor. FNA cytology was performed using five passes with a 22\u2010gauge needle. The smears were moderately cellular consisting of sheets and large, loosely cohesive clusters of ovoid to spindle cells with indistinct cytoplasmic borders and abundant cytoplasm, peppered with numerous small mature lymphocytes. The nuclei of the tumor cells were oval with finely granular chromatin with frequent nuclear grooves, pseudoinclusions, and easily recognizable mitotic figures. The tumor cells were positive for FDCS markers (CD21, CD23, and CD35).<\/jats:p>","DOI":"10.1002\/dc.25132","type":"journal-article","created":{"date-parts":[[2023,3,31]],"date-time":"2023-03-31T03:18:21Z","timestamp":1680232701000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Fine needle aspiration cytology of follicular dendritic cell sarcoma of the stomach masquerading as gastrointestinal stromal tumor: A case report of a unique entity with emphasis on cytomorphology"],"prefix":"10.1002","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-2011-5710","authenticated-orcid":false,"given":"Alex H.","family":"Shacklette","sequence":"first","affiliation":[{"name":"Department of Pathology and Laboratory Medicine Indiana University School of Medicine  Indianapolis Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8225-6875","authenticated-orcid":false,"given":"Shaoxiong","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine Indiana University School of Medicine  Indianapolis Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John M.","family":"DeWitt","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Indiana University School of Medicine  Indianapolis Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krunal S.","family":"Patel","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Indiana University School of Medicine  Indianapolis Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4584-9222","authenticated-orcid":false,"given":"Omer A.","family":"Saeed","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine Indiana University School of Medicine  Indianapolis Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,3,31]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.3747\/co.21.2091"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.5858\/arpa.2016-0126-RS"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/03000605221097662"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/0300060520920433"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/jcp.30662"},{"issue":"3","key":"e_1_2_8_7_1","first-page":"562","article-title":"A primary lymph node malignancy with features suggestive of dendritic reticulum cell differentiation.
