Intestinal polyp - intestinal polyp

Japanese: 腸管ポリープ - ちょうかんポリープ(英語表記)intestinal polyp
Intestinal polyp - intestinal polyp
A general term for localized tumors (polyps) that protrude into the intestinal lumen. They may originate from the mucosal epithelium or from submucosal tumors. As such, their morphology is diverse, ranging from spherical, mobile with a stalk, to hemispherical without a stalk, or even slightly elevated. They may range in size to the point of blocking the lumen. They may be single or multiple. When there are more than 100 of them, the term polyposis is used. Depending on the tissue that makes up the tumor, they may be classified as tumorous or non-tumorous.

Japanese:
腸管内腔に突出する限局性腫瘤(ポリープ)の総称。粘膜上皮に由来することもあり,粘膜下腫瘍によることもある。したがって形態も多様で,球状で茎をもって移動するものから,茎のない半球状や,ごくわずかな高まりを示すものまである。大きさも管腔をふさぐほどの大きさに及ぶものまである。単一のこともあり,多発のこともある。100個以上多発する場合,ポリポーシスという名称が用いられる。腫瘤を構成している組織により,腫瘍性と非腫瘍性とに分ける。
