We report a case of anaplastic lymphoma kinase (ALK)\u2010positive small bowel IMT detected by capsule endoscopy (CE). A 24\u2010year\u2010old woman presented with epigastric pain. Contrast\u2010enhanced computed tomography revealed a 2\u2010cm mass in the small intestine. Double\u2010balloon endoscopy was attempted but failed to reach the lesion. CE demonstrated a submucosal tumor\u2010like protrusion with mild surface erythema and conspicuous whitish villous changes. Laparoscopy\u2010assisted partial resection of the small intestine was performed, and histopathological examination with immunohistochemistry confirmed ALK\u2010positive IMT. The postoperative course was uneventful, and no recurrence was observed during 8 months of follow\u2010up. This case indicates that CE can provide clinically useful information for the evaluation of small bowel submucosal lesions beyond the reach of conventional endoscopy. IMT should be considered in the differential diagnosis of erythematous small bowel tumors in young patients.<\/jats:p>","DOI":"10.1002\/deo2.70327","type":"journal-article","created":{"date-parts":[[2026,4,11]],"date-time":"2026-04-11T12:05:37Z","timestamp":1775909137000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Primary Anaplastic Lymphoma Kinase\u2010Positive Inflammatory Myofibroblastic Tumor of the Small Bowel Detected by Capsule Endoscopy: A Case Report"],"prefix":"10.1002","volume":"6","author":[{"given":"Tomoyuki","family":"Niwa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasushi","family":"Hamaya","sequence":"additional","affiliation":[{"name":"First Department of Medicine Hamamatsu University School of Medicine  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Asai","sequence":"additional","affiliation":[{"name":"First Department of Medicine Hamamatsu University School of Medicine  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsuhiro","family":"Ito","sequence":"additional","affiliation":[{"name":"First Department of Medicine Hamamatsu University School of Medicine  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoru","family":"Takahashi","sequence":"additional","affiliation":[{"name":"First Department of Medicine Hamamatsu University School of Medicine  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shunya","family":"Onoue","sequence":"additional","affiliation":[{"name":"First Department of Medicine Hamamatsu University School of Medicine  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Osawa","sequence":"additional","affiliation":[{"name":"Department of Endoscopic and Photodynamic Medicine Hamamatsu University School of Medicine  Shizuoka Japan"},{"name":"Department of Advanced Medical Science for Regional Collaboration Hamamatsu University School of Medicine  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mayu","family":"Sakata","sequence":"additional","affiliation":[{"name":"Second Department of Surgery Hamamatsu University School of Medicine  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroya","family":"Takeuchi","sequence":"additional","affiliation":[{"name":"Second Department of Surgery Hamamatsu University School of Medicine  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ken","family":"Sugimoto","sequence":"additional","affiliation":[{"name":"First Department of Medicine Hamamatsu University School of Medicine  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,11]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/94.5.538"},{"key":"e_1_2_11_3_1","volume-title":"WHO Classification of Tumours of Soft Tissue and Bone","author":"Fletcher C.
