The paper reports a 42-year-old woman with a painful, irreducible right inguinal mass that had been present for six months and worsened with menstruation, initially diagnosed via CT and MRI as inguinal endometriosis associated with an inguinal hernia. Exploratory laparoscopy confirmed no obvious intra-abdominal ectopic endometriosis and identified a right external inguinal hernia, and the authors performed tumor excision combined with a front-approach approach for hernia repair; pathology established the final diagnosis as endometriosis. The authors note a limitation inherent to case reports and cite that other reports describe recurrence at the same or different sites after inguinal lesion excision, though in this single patient there was no recurrence over four years. This paper is centrally about endometriosis — specifically inguinal (inguinial) endometriosis managed with exploratory laparoscopy to assess concurrent lesions.

Abstract

症例は42歳の女性で，半年前からの月経に伴う右鼠径部の有痛性腫瘤を主訴に受診した．右鼠径部に15 mm大の圧痛を伴う腫瘤を認め還納は不能であった．CTおよびMRIで右鼠径部に腹腔内から連続する軟部腫瘤を認め，鼠径ヘルニアに合併した鼠径部子宮内膜症と術前診断した．挙児希望があり，診断および切除を目的に手術を施行した．審査腹腔鏡で腹腔内に明らかな異所性子宮内膜症がないことと右外鼠径ヘルニアを確認した．前方アプローチを併用し，腫瘤の摘出とヘルニア修復術を行った．病理検査で子宮内膜症と最終診断した．術後4年，他の部位を含め子宮内膜症の再発を認めていない．鼠径部病変切除後に同所性または異所性に再発した報告例も散見するため，特に挙児希望などで術後に薬物療法を行えない症例では，審査腹腔鏡で併発病変の有無を確認することは有用であると考えられた．
