粘液性嚢胞腫瘍との鑑別が困難であった単胞性の漿液性嚢胞腫瘍の1例

米田傑,張淑美,伊藤哲也,丸山雅史,児玉亮,尾崎弥生,村木崇,浜野英明,新倉則和,上原剛,宮川眞一,田中榮司
日本消化器病学会雑誌 108(11), 1916-1923, 2011
症例は40歳代女性．膵尾部単胞性嚢胞にて経過観察中，1年半の経過で増大を認めた．嚢胞内に隔壁様構造を認め，cyst in cystの形態を示したため粘液性嚢胞腫瘍を疑い切除したが，病理組織学的に単胞性の漿液性嚢胞腫瘍であった．画像所見の経過と病理所見からは嚢胞の増大は出血によるものと推測され，また隔壁様構造は肉芽組織であった．多彩な形態をとる漿液性嚢胞腫瘍の診断において，貴重な症例と考えられた.
