臨床医の考える臨床画像と病理所見の対比—小腸

Clinician's Consideration of Clinical Images and Pathological Findings in the Small Intestine

要旨●小腸病変の臨床画像と病理組織学的所見の対比について，Meckel憩室内翻症，小腸GIST，小腸Peutz-Jeghers型ポリープの3例を提示する．臨床上注目する部位に割を入れ，病理組織像と対比する必要がある．X線造影検査・内視鏡検査時には，ルーペ像・病理組織像を想像しながら施行するよう心がける．また切除した病理標本は必ず自ら顕微鏡で確認し，臨床所見と病理組織学的所見について病理医とディスカッションする姿勢が肝要である．

　Three cases of small intestinal lesions—Meckel's diverticulum, small intestinal gastrointestinal stromal tumor, and Peutz−Jeghers-type polyps—are presented here to illustrate the contrast between clinical images and pathological findings. The clinical focus of each case should be created and compared with the histopathology. Additionally, cross-sectional and histopathological images should be analyzed during radiographic and endoscopic examinations. It is also crucial to examine the excised pathological specimen under a microscope and discuss the clinical and histopathological findings with a pathologist.
