Ustekinumab, an IL-12\/23 inhibitor, impairs Th1\/Th17 immunity which is critical for fungal control. No prior cases link ustekinumab use to disseminated fungal disease. We report a 45-year-old woman from an endemic region with prior pulmonary coccidioidomycosis and psoriatic arthritis on ustekinumab who presented with malignant-appearing ascites and omental caking. Fluid studies were non-diagnostic, but laparoscopic biopsies confirmed disseminated Coccidioides infection. She improved with liposomal amphotericin B followed by oral fluconazole suppression. This case highlights the need to consider peritoneal coccidioidomycosis in immunosuppressed patients, particularly on IL-12\/23 blockade, and underscores the role of tissue diagnosis when fluid studies are negative.<\/jats:p>","DOI":"10.1093\/jscr\/rjaf978","type":"journal-article","created":{"date-parts":[[2025,11,21]],"date-time":"2025-11-21T13:19:58Z","timestamp":1763731198000},"source":"Crossref","is-referenced-by-count":1,"title":["Disseminated peritoneal coccidioidomycosis mimicking malignancy in an immunosuppressed patient: a case report"],"prefix":"10.1093","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5847-9577","authenticated-orcid":false,"given":"Ryan","family":"Meyer","sequence":"first","affiliation":[{"name":"Department of Surgery, Los Robles Regional Medical Center , 215 W Janss Rd, Thousand Oaks, CA 91360 ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamir","family":"Bresler","sequence":"additional","affiliation":[{"name":"Department of Surgery, Los Robles Regional Medical Center , 215 W Janss Rd, Thousand Oaks, CA 91360 ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kevin","family":"Palmer","sequence":"additional","affiliation":[{"name":"Department of Surgery, Los Robles Regional Medical Center , 215 W Janss Rd, Thousand Oaks, CA 91360 ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makrouhi","family":"Kademian","sequence":"additional","affiliation":[{"name":"Department of Surgery, Los Robles Regional Medical Center , 215 W Janss Rd, Thousand Oaks, CA 91360 ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,12,12]]},"reference":[{"key":"2025121211454668100_ref1","doi-asserted-by":"publisher","first-page":"e112","DOI":"10.1093\/cid\/ciw360","article-title":"2016 Infectious Diseases Society of America (IDSA) clinical practice guideline for the treatment of coccidioidomycosis","volume":"63","author":"Galgiani","year":"2016","journal-title":"Clin Infectious Dis"},{"key":"2025121211454668100_ref2","doi-asserted-by":"publisher","first-page":"e2513572","DOI":"10.1001\/jamanetworkopen.2025.13572","article-title":"Estimated burden of coccidioidomycosis","volume":"8","author":"Williams","year":"2025","journal-title":"JAMA Netw Open"},{"key":"2025121211454668100_ref3","doi-asserted-by":"publisher","first-page":"971","DOI":"10.1086\/313808","article-title":"Peritoneal coccidioidomycosis: case report and review","volume":"30","author":"Phillips","year":"2000","journal-title":"Clin Infect Dis"},{"key":"2025121211454668100_ref4","doi-asserted-by":"publisher","first-page":"ofac017","DOI":"10.1093\/ofid\/ofac017","article-title":"Coccidioidal peritonitis: a review of 17 cases.
