It was reported via a journal article: title: oxidized regenerated cellulose (surgicel®) on cytology/histology authors: elizabeth m kurian, et al.Citation: acta cytol.2022 jul 27;1-4.Doi: 10.1159/000525857.In patients with a history of malignancy, follow-up surveillance of lymph nodes is required to evaluate for potential malignancy or infection.In some cases, the lymphadenopathy may be secondary to an intraprocedural hemostatic agent and/or related granulomatous reaction.This study presents a case of an 80-year-old female patient 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 lymph node was negative for malignancy.Reported complications include: a 10-month surveillance positron emission tomography scan showed new mildly avid mediastinal and right hilar lymph nodes.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® (or oxidized regenerated cellulose) was placed during surgery at the station 7 site.In conclusion, assessment of the findings and based on the similar histologic appearance reported in previous cases associated with surgicel® [ann thorac med.2017;12(1):55-6, cancer cytopathol.2019;127(12):765-70, and arch bronconeumol.2020;56(7):459-71], the station 7 acellular, amorphous, and hyaline-like exogenous material found in our case was interpreted as hemostatic agent compatible with surgicel® (or oxidized regenerated cellulose).This case highlights the importance of cytologic/histologic recognition of hemostatic agents, specifically oxidized cellulose mesh.
