In some cases, the lymphadenopathy may be secondary to an intraprocedural hemostatic agent and\/or related granulomatous reaction. &lt;b&gt;&lt;i&gt;Case Presentation:&lt;\/i&gt;&lt;\/b&gt; We present the case of an 80-year-old female with a remote past medical history of breast cancer status post-lumpectomy and chemoradiation. Twenty years later, a 2.4 cm pulmonary right middle lobe nodule was noted on imaging studies. She underwent bronchoscopy, cervical mediastinoscopy, and right middle lobe wedge resection. The final pathologic diagnosis was a pulmonary carcinoid tumor, and the excised mediastinal LN was negative for malignancy. A 10-month surveillance positron emission tomography scan showed new mildly avid mediastinal and right hilar LNs. The following endobronchial ultrasound-guided transbronchial needle aspiration showed unremarkable lymphoid elements in the enlarged 4R LN, while the station 7 LN demonstrated ample dense hyaline-like foreign material. Subsequent review of the cell block\/biopsy and communication with the thoracic surgeon revealed that Surgicel\u00ae (or oxidized regenerated cellulose) was placed during surgery at the station 7 site. &lt;b&gt;&lt;i&gt;Discussion\/Conclusion:&lt;\/i&gt;&lt;\/b&gt; Assessment of the findings and based on the similar histologic appearance reported in previous cases associated with Surgicel\u00ae [&lt;i&gt;Ann Thorac Med&lt;\/i&gt;. 2017;12(1):55\u20136, &lt;i&gt;Cancer Cytopathol&lt;\/i&gt;. 2019;127(12):765\u201370, and &lt;i&gt;Arch Bronconeumol&lt;\/i&gt;. 2020;56(7):459\u201371], the station 7 acellular, amorphous, and hyaline-like exogenous material found in our case was interpreted as hemostatic agent compatible with Surgicel\u00ae (or oxidized regenerated cellulose). This case highlights the importance of cytologic\/histologic recognition of hemostatic agents, specifically oxidized cellulose mesh. <\/jats:p>","DOI":"10.1159\/000525857","type":"journal-article","created":{"date-parts":[[2022,7,27]],"date-time":"2022-07-27T21:00:37Z","timestamp":1658955637000},"page":"556-559","source":"Crossref","is-referenced-by-count":4,"title":["Oxidized Regenerated Cellulose (Surgicel\u00ae) on Cytology\/Histology"],"prefix":"10.1159","volume":"66","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7761-1676","authenticated-orcid":false,"given":"Elizabeth M.","family":"Kurian","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhanned","family":"Abu-Hijleh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4738-6268","authenticated-orcid":false,"given":"Tricia Rood","family":"Lowrey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0458-4157","authenticated-orcid":false,"given":"Luis Eduardo","family":"De Las Casas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2022,7,27]]},"reference":[{"key":"ref1"},{"key":"ref2"},{"key":"ref3"},{"key":"ref4"},{"key":"ref5"},{"key":"ref6"},{"key":"ref7"},{"key":"ref8"}],"container-title":["Acta Cytologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/525857","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/525857","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:10:07Z","timestamp":1745421007000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000525857"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022]]},"references-count":8,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2022,11,3]]},"published-print":{"date-parts":[[2022,11,9]]}},"URL":"https:\/\/doi.org\/10.1159\/000525857","archive":["Portico"],"relation":{},"ISSN":["0001-5547","1938-2650"],"issn-type":[{"value":"0001-5547","type":"print"},{"value":"1938-2650","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022]]}}}
