<strong>Tóm tắt</strong> U mô đệm đường tiêu hóa (Gastrointestinal Stromal Tumor – GIST) hầu hết nằm ở dạ dày, ruột non, đại trực tràng, hiếm gặp ở tá tràng. Chúng tôi báo cáo một trường hợp GIST tá tràng hiếm gặp ở người bệnh nữ 48 tuổi được chẩn đoán qua cắt lớp vi tính (CLVT) và nội soi thực quản – dạ dày – tá tràng, đã được phẫu thuật và khẳng định bằng kết quả giải phẫu bệnh. <em>Từ khóa:</em> U mô đệm đường tiêu hóa, GIST, u tá tràng. <strong> </strong> <strong>Tài liệu tham khảo</strong> <ol> <li>Ito T, Kushida T, Sakurada M, Tanaka K, Sato K, Maekawa H.

We report a rare case of duodenal GIST in a 48-year-old female patient identified with computed tomography scan (CT scan), esophagogastroduodenoscopy, and confirmed by histopathology examinations. <em>Keywords:</em> Gastrointestinal stromal tumor, GIST, Duodenal Tumor. <strong> </strong> <strong>References </strong> <ol> <li>Ito T, Kushida T, Sakurada M, Tanaka K, Sato K, Maekawa H.
