We present the case of a 57\u2010year\u2010old male with a medical history notable for hypertension, photosensitivity, arthritis, and malar rash, who presented with 6\u2009weeks of persistent epigastric pain. Computed Tomography (CT) of the abdomen revealed hallmark features such as fat stranding around the pancreatic tail and gallbladder wall thickening, confirming the diagnosis of acute pancreatitis and cholecystitis. Post\u2010cholecystectomy, histopathological examination of the gallbladder displayed IgG4\u2010positive staining in multiple vessels, accompanied by perivascular inflammation and fibrinoid necrosis infiltrated by lymphocytes and neutrophils, confirming the diagnosis of IgG4\u2010RD. Subsequent evaluation prompted by systemic manifestations revealed an ANA titer of 1:5120 and a dsDNA titer of 1:80, leading to the diagnosis of SLE. The patient later developed mononeuropathy, which improved upon initiation of immunosuppressive therapy. This case underscores the intricate interplay between IgG4\u2010RD and SLE, an association documented to a limited extent in literature, thereby emphasizing the imperative of considering alternative autoimmune diseases with manifestations akin to IgG4\u2010RD.<\/jats:p>","DOI":"10.1002\/ccr3.70163","type":"journal-article","created":{"date-parts":[[2025,4,4]],"date-time":"2025-04-04T21:12:09Z","timestamp":1743801129000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<scp>IgG4<\/scp>\n                    \u2010Related Disease (\n                    <scp>IgG4<\/scp>\n                    \u2010\n                    <scp>RD<\/scp>\n                    ) Autoimmune Pancreatitis (\n                    <scp>AIP<\/scp>\n                    ) as an Initial Presentation of Systemic Lupus Erythematosus (\n                    <scp>SLE<\/scp>\n                    )"],"prefix":"10.1002","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-5697-8867","authenticated-orcid":false,"given":"Srilatha","family":"Kothandaraman","sequence":"first","affiliation":[{"name":"Department of Rheumatology Texas A&amp;M University College of Medicine, Baylor University Medical Center  Dallas Texas USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rithwik","family":"Terala","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Texas A&amp;M University College of Medicine, Baylor University Medical Center  Dallas Texas USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,4,4]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra1104650"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140\u20106736(14)60720\u20100"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2018.06.082"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/kez667"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2020.01047"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/annrheumdis-2022-eular.5058"},{"key":"e_1_2_13_8_1","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/keac284"},{"key":"e_1_2_13_9_1","doi-asserted-by":"publisher","DOI":"10.1093\/mrcr\/rxac002"},{"key":"e_1_2_13_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/0961203319840430"},{"key":"e_1_2_13_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000013545"},{"key":"e_1_2_13_12_1","doi-asserted-by":"publisher","DOI":"10.1177\/2324709619862297"},{"key":"e_1_2_13_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/modpathol.2012.72"},{"key":"e_1_2_13_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.40930"},{"key":"e_1_2_13_15_1","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/key227"},{"key":"e_1_2_13_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.39205"},{"key":"e_1_2_13_17_1","doi-asserted-by":"publisher","DOI":"10.1038\/gene.2009.39"},{"key":"e_1_2_13_18_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41584\u2010019\u20100235\u20105"},{"key":"e_1_2_13_19_1","doi-asserted-by":"publisher","DOI":"10.4103\/injr.injr_265_21"},{"key":"e_1_2_13_20_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12883\u2010021\u201002069\u2010z"},{"key":"e_1_2_13_21_1","doi-asserted-by":"publisher","DOI":"10.5692\/clinicalneurol.54.1047"},{"key":"e_1_2_13_22_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamaneurol.2013.658"}],"container-title":["Clinical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccr3.70163","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T14:54:38Z","timestamp":1764255278000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccr3.70163"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4]]},"references-count":21,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2025,4]]}},"alternative-id":["10.1002\/ccr3.70163"],"URL":"https:\/\/doi.org\/10.1002\/ccr3.70163","archive":["Portico"],"relation":{},"ISSN":["2050-0904","2050-0904"],"issn-type":[{"type":"print","value":"2050-0904"},{"type":"electronic","value":"2050-0904"}],"subject":[],"published":{"date-parts":[[2025,4]]},"assertion":[{"value":"2024-01-31","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-01-18","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-04-04","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70163"}}
