Its association with autoimmune phenomena remains unclear. We report a woman in her twenties with a prior diagnosis of lung IMT who re\u2010presented with chronic respiratory symptoms, systemic features and radiological progression. Repeat evaluation revealed bilateral bronchocentric consolidation, positive antinuclear antibodies and histopathological findings consistent with fibro\u2010inflammatory disease, without ALK expression or significant IgG4 infiltration. Concomitant erythema nodosum supported an autoimmune process. Repeat biopsy did not fully reproduce the original IMT morphology, and follow\u2010up remains limited. She had significant clinical, functional and radiological improvement following immunosuppressive therapy. This case emphasizes the diagnostic complexity of lung masses in young patients and emphasizes the importance of considering autoimmune\u2010associated IMT as a potentially reversible condition.<\/jats:p>","DOI":"10.1002\/rcr2.70621","type":"journal-article","created":{"date-parts":[[2026,5,15]],"date-time":"2026-05-15T02:06:52Z","timestamp":1778810812000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Autoimmune\u2010Associated Pulmonary Inflammatory Myofibroblastic Tumour: A Diagnostic and Therapeutic Challenge"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0750-3087","authenticated-orcid":false,"given":"Ng Boon","family":"Hau","sequence":"first","affiliation":[{"name":"Department of Medicine, Faculty of Medicine University Kebangsaan Malaysia, Hospital Canselor Tuanku Muhriz  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Low Hsueh","family":"Jing","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology and Critical Care, Faculty of Medicine University Kebangsaan Malaysia, Hospital Canselor Tuanku Muhriz  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nik Nuratiqah Nik","family":"Abeed","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine University Kebangsaan Malaysia, Hospital Canselor Tuanku Muhriz  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nor Safiqah","family":"Sharil","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine University Kebangsaan Malaysia, Hospital Canselor Tuanku Muhriz  Kuala Lumpur Malaysia"},{"name":"Internal Medical Unit, Faculty of Medicine and Health Science Universiti Sains Islam Malaysia  Nilai Negeri Sembilan Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nurul Aisyah Abd","family":"Rahman","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine University Kebangsaan Malaysia, Hospital Canselor Tuanku Muhriz  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Badrul Iskandar Abdul","family":"Wahab","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Laboratory Services, Faculty of Medicine Universiti Kebangsaan Malaysia, Hospital Canselor Tuanku Muhriz  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rose Azzlinda","family":"Osman","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine University Kebangsaan Malaysia, Hospital Canselor Tuanku Muhriz  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3788-4789","authenticated-orcid":false,"given":"Andrea Ban","family":"Yu\u2010Lin","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine University Kebangsaan Malaysia, Hospital Canselor Tuanku Muhriz  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,14]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"109","volume-title":"WHO Classification of Tumours: Soft Tissue and Bone Tumours","author":"Antonescu C.
