Evaluation showed ileocaecal ulcers, cytopenias and Trisomy 8-positive myelodysplastic syndrome (MDS). The constellation of mucocutaneous and gastrointestinal Beh\u00e7et-like features with clonal haematopoiesis led to the diagnosis of Trisomy 8-Associated Autoinflammatory Disease (TRIAD), also known as Beh\u00e7et-like intestinal disease with MDS. She initially responded to corticosteroids and azacitidine, but relapsed whenever steroids were tapered below 10\u2009mg\/day, reflecting a refractory, steroid-dependent course. Management targeted the underlying high-risk MDS with azacitidine, which also exerted potent anti-inflammatory effects. Other advanced therapies, including biologic agents used for primary Beh\u00e7et\u2019s disease, were not considered appropriate due to the patient\u2019s high-risk MDS and cytopenias. This case underscores the importance of recognising TRIAD in South Asia, where overlap with tuberculosis and inflammatory bowel disease may delay diagnosis, and highlights azacitidine\u2019s dual role and haematopoietic stem cell transplantation as the only definitive option. This case was managed between 2023 and 2024, raising the possibility of concurrent or prior SARS-CoV-2 infection contributing to the observed immune dysregulation, a factor increasingly recognised in autoinflammatory conditions.<\/jats:p>","DOI":"10.1136\/bcr-2025-269045","type":"journal-article","created":{"date-parts":[[2026,1,12]],"date-time":"2026-01-12T15:30:15Z","timestamp":1768231815000},"page":"e269045","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Beh\u00e7et-like
