We present a case of a woman in her late 20s with systemic lupus erythematosus who presented with fever as the chief complaint. Imaging revealed a hepatic mass, and pathology confirmed the diagnosis of hepatic follicular dendritic cell sarcoma. The patient showed no recurrence 1 year post-radical surgery. We analyzed a total of 43 cases from 32 previous reports and the present case. Among these, the mean age at onset was 48 years, the median maximum tumor diameter was 87.5\u2009mm, and there was a female predominance. Survival analysis showed that the 5-year disease-free survival of patients was 63.4%. This case and literature review highlight the rarity and diagnostic challenges of primary hepatic follicular dendritic cell sarcoma, especially in patients with atypical presentations such as fever of unknown origin. Early recognition and radical surgery are crucial for a favorable prognosis.<\/jats:p>","DOI":"10.1177\/03000605251405692","type":"journal-article","created":{"date-parts":[[2025,12,27]],"date-time":"2025-12-27T10:44:16Z","timestamp":1766832256000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Primary hepatic follicular dendritic cell sarcoma: A case study and literature review"],"prefix":"10.1177","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3339-8700","authenticated-orcid":false,"given":"Junjie","family":"Zhu","sequence":"first","affiliation":[{"name":"Key Laboratory of Carcinogenesis and Translational Research (Ministry of Education\/Beijing), Department of Gastrointestinal Surgery IV, Peking University Cancer Hospital &amp; Institute, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying","family":"Liang","sequence":"additional","affiliation":[{"name":"Peking University Third Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Zhang","sequence":"additional","affiliation":[{"name":"Peking University Third Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bingqi","family":"Li","sequence":"additional","affiliation":[{"name":"Peking University Third Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danfeng","family":"Zheng","sequence":"additional","affiliation":[{"name":"Peking University Third Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hangyan","family":"Wang","sequence":"additional","affiliation":[{"name":"Peking University Third Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,12,27]]},"reference":[{"key":"e_1_3_10_2_2","first-page":"562","article-title":"A primary lymph node malignancy with features suggestive of dendritic reticulum cell differentiation. a report of 4 cases","volume":"122","author":"Monda L","year":"1986","unstructured":"Monda L, Warnke R, Rosai J.
