Gallbladder involvement is exceedingly rare and poses significant diagnostic challenges. Few cases in the literature describe gallbladder follicular lymphoma, particularly in elderly male patients, leaving notable gaps in clinical understanding and management. Herein, we present the case of an 82-year-old male who presented with acute abdominal pain and unintentional weight loss. Initial imaging, including contrast-enhanced computed tomography, ultrasound, and magnetic resonance imaging, revealed a suspicious gallbladder mass with wall thickening and regional lymphadenopathy, raising concern for malignancy. Endoscopic ultrasound-guided fine needle aspiration and subsequent immunophenotyping confirmed a diagnosis of PFL. The patient underwent radical cholecystectomy with lymphadenectomy, and histopathological examination corroborated the diagnosis of gallbladder follicular lymphoma. During follow-up, the patient developed complications, yet no evidence of lymphoma recurrence was observed. A literature review identified 8 similar cases, further emphasizing the rarity of this presentation. Future research should focus on optimizing diagnostic techniques, refining therapeutic strategies, and conducting longer-term follow-up studies to better assess patient outcomes in such a rare disease. This case highlights the need for heightened clinical suspicion and comprehensive evaluation in atypical presentations of extranodal lymphoma.<\/jats:p>","DOI":"10.1177\/23247096251342035","type":"journal-article","created":{"date-parts":[[2025,5,28]],"date-time":"2025-05-28T01:17:47Z","timestamp":1748395067000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Follicular Lymphoma of the Gallbladder in an Octogenarian: A Case Report and Literature Review"],"prefix":"10.1177","volume":"13","author":[{"given":"Mikayla","family":"Myers","sequence":"first","affiliation":[{"name":"Joan Edwards School of Medicine, Huntington, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bassel","family":"Dakkak","sequence":"additional","affiliation":[{"name":"Joan Edwards School of Medicine, Huntington, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Swapna","family":"Sirigireddy","sequence":"additional","affiliation":[{"name":"Joan Edwards School of Medicine, Huntington, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ibrahim","family":"Shanti","sequence":"additional","affiliation":[{"name":"Joan Edwards School of Medicine, Huntington, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Drew","family":"Ferguson","sequence":"additional","affiliation":[{"name":"Joan Edwards School of Medicine, Huntington, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdelwahap","family":"Elghezewi","sequence":"additional","affiliation":[{"name":"Joan Edwards School of Medicine, Huntington, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mustafa","family":"Ben Khayal","sequence":"additional","affiliation":[{"name":"Joan Edwards School of Medicine, Huntington, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1092-3565","authenticated-orcid":false,"given":"Zakaria","family":"Alagha","sequence":"additional","affiliation":[{"name":"Joan Edwards School of Medicine, Huntington, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed","family":"Sherif","sequence":"additional","affiliation":[{"name":"Joan Edwards School of Medicine, Huntington, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eva-Pattont","family":"Tackett","sequence":"additional","affiliation":[{"name":"Joan Edwards School of Medicine, Huntington, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,5,27]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2005-06-2508"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1023\/A:1008282818705"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdn525"},{"key":"e_1_3_3_5_2","first-page":"2242","article-title":"Primary lymphoma of the gallbladder; case report and review of the literature","volume":"91","author":"Chatila R","year":"1996","unstructured":"Chatila R, Fiedler PN, Vender RJ.
