摘要

在臨床上胃炎性肌纖維母細胞腫瘤發生在成人為非常罕見。我們的病例報告中描述一位55歲婦人罹患胃炎性肌纖維母細胞腫瘤。該病患有升結腸腺癌並接受右半結腸切除術之過去病史。當時在大腸癌術前之腹部電腦斷層檢查顯示除了升結腸腫瘤外，並無發現胃部腫瘤。但在術後一年之腹部電腦斷層追蹤檢查中，意外發現一顆約3公分胃部腫瘤。同時該病患無腹部不適之情形。進而安排上胃腸道內視鏡作進一步檢查。上胃腸道內視鏡顯示一顆約3公分之粘膜下腫瘤位於胃體部（胃大彎側），疑似胃基質腫瘤所致。因此，患者接受外科手術切除胃部腫瘤。最後，病理報告為胃炎性肌纖維母細胞腫瘤。在術後追蹤一年後，目前無復發之情形。

Stomach involvement by inflammatory myofibroblastic tumor (IMT) in adults is extremely rare. We present a 55-year-old woman with a gastric IMT. A gastric mass was found incidentally while performing an abdominal computed tomography (CT) screen examination due to a prior history of adenocarcinoma of the ascending colon with right hemicolectomy after 1-year follow up. Previously abdominal CT revealed no gastric tumor before the right hemicolectomy. Abdominal CT showed a round shaped, protruding, and hypo-attenuated mass of approximately 3.0 cm in diameter in stomach. Upper gastrointestinal endoscopy revealed one submucosal mass of approximately 3.0 cm in diameter, located at the greater curvature side of the middle gastric body. Submucosal tumor, such as gastrointestinal stromal tumor (GIST) was highly suspected initially. After surgical resection, the pathological diagnosis was consistent with an IMT that originated from the gastric wall. No tumor recurrence was noted after 1-year follow-up.
