Pseudoinvasion of the colon and rectal tumors is characterized by the presence of epithelial tubules in the submucosal layer, in continuity with the neoplastic tissue across the line of the muscularis mucosae into the submucosa. To our knowledge, this is the second report of a case of a rectal LST with pseudoinvasion after resection of the rectal adenoma. A 74-year-old man was admitted to our department for the resection of a rectal tumor above the anal canal. When he was 58 years old, a rectal adenoma had been detected near the anal canal. Although transanal resection was performed, the polyp had recurred the following year, and the patient had again undergone transanal resection. After 12 years, a lesion was detected at the same site; the lesion showed a tendency to increase in size. Further evaluation revealed that it was a rectal LST extending to the dentate line of the anal canal. Endoscopic resection could not be performed, because the patient had undergone brachytherapy for prostate cancer; hence, laparoscopic assisted abdominoperineal resection was performed. He was transferred to the referring hospital on the 17th postoperative day without complications. The final pathologic diagnosis was rectal serrated adenoma with pseudoinvasion under the anoderm without malignancy. Tumors extending to the anal canal should be evaluated carefully so as to facilitate appropriate treatment, as recurrence of a rectal polyp may suggest pseudoinvasion of an adenoma.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"（背景） 歯状線にかかる直腸側方発育型腫瘍は，しばしば治療に難渋することがある．また大腸腫瘍の偽浸潤は，多くが有茎性病変であり側方発育型の形態で認めることは稀である．今回，われわれは肛門上皮下に側方発育型腫瘍の形態で偽浸潤を呈した症例を経験したので報告する．（症例） 74歳，男性．58歳時に直腸ポリープに対して経肛門的切除術を受けたが，翌年再発し再手術を受けた．その12年後に同部位に病変を認め，直腸側方発育型腫瘍の診断となった．前立腺小線源療法後であり内視鏡的切除は困難と判断され当科へ紹介となった．腫瘍は50×45mm大の4/5周性で，NBI（Narrow Band Imaging）観察で肛門上皮下への進展所見を認め，腹腔鏡下直腸切断術を施行した．最終病理診断は直腸鋸歯状腺腫で悪性所見は無く，肛門上皮下に腺腫の偽浸潤を認めた．（結語） まれながら大腸腫瘍切除術後の切除創には腺腫の偽浸潤が出現する可能性があり，慎重に治療方針を検討する必要がある．","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03685063","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040104","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"490","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"保坂, 優斗","creatorNameLang":"ja"},{"creatorName":"HOZAKA, Yuto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"138486","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"盛, 真一郎","creatorNameLang":"ja"},{"creatorName":"MORI, Shinichirou","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"138487","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"喜多, 芳昭","creatorNameLang":"ja"},{"creatorName":"KITA, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"138488","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"馬場, 研二","creatorNameLang":"ja"},{"creatorName":"BABA, Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"138489","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田辺, 寛","creatorNameLang":"ja"},{"creatorName":"TANABE, Kan","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"138490","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"夏越, 祥次","creatorNameLang":"ja"},{"creatorName":"NATSUGOE, Shoji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"138491","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-03-11"}],"displaytype":"detail","filename":"AN00040104_72_p1-7.pdf","filesize":[{"value":"614.9 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040104_72_p1-7","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/15675/files/AN00040104_72_p1-7.pdf"},"version_id":"e0261745-5137-4bc6-8088-1130caacb22b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Pseudoinvasion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Adenoma","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lateral spreading tumor","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"側方発育型腫瘍の形態で偽浸潤を呈した直腸腺腫の 1 例","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"側方発育型腫瘍の形態で偽浸潤を呈した直腸腺腫の 1 例","subitem_title_language":"ja"},{"subitem_title":"Lateral Spreading Tumor of the Rectal Adenoma with Anoderm Pseudoinvasion : A Case Report","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["59","5994"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-03-11"},"publish_date":"2021-03-11","publish_status":"0","recid":"15675","relation_version_is_last":true,"title":["側方発育型腫瘍の形態で偽浸潤を呈した直腸腺腫の 1 例"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-05-27T05:39:42.831188+00:00"}
