He was diagnosed with IgG4-related autoimmune pancreatitis. Initial corticosteroid therapy achieved only temporary remission, with disease relapse occurring after 4 months. Rituximab was subsequently introduced, resulting in sustained disease control by depleting B lymphocytes and reducing disease flares, consistent with previous reports. The patient has remained clinically stable for 1\u2005year. This case highlights the clinical presentation, diagnostic challenges, and therapeutic considerations of this rare condition.<\/jats:p>","DOI":"10.3389\/fped.2025.1594539","type":"journal-article","created":{"date-parts":[[2025,9,25]],"date-time":"2025-09-25T07:01:10Z","timestamp":1758783670000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Case
