概要

23歳,未婚婦人におげる卵巣漿液性嚢胞腺腫(低悪性度)に合併した悪性旁卵巣腫瘍の極めて稀な1症例を報告した.旁卵巣腫蕩は10×l0×9cm大で,左広間膜に位置し,単胞性嚢胞状で,内腔に面して小乳頭状の増殖を示していた.組織学的には分化型の乳頭状漿液性嚢胞腺癌で,腫瘍細胞は比較的背が低く,3〜4層までの増殖を示し,時に絨毛を有するものも混している.異型性も可成り認められるところもあり,リンバ管内浸潤を疑わぜる部分もあるが,核分裂像は稀である.電顕的にもこれら細胞形態像は確かめちれている.右卵巣腫瘍は8x7×6cm大,左は6×4×4cm大で,何れも多胞性嚢胞状で組織学的に右は乳頭状漿液性嚢胞腺腫(低悪性度)で,左は良性の漿液性嚢胞腺腫である.旁卵巣腫蕩および右卵巣腫瘍の一部に,銀好性細胞が認められたことは全く新しい発見であり,その意義に関しては今後の研究に残されている.息者は術後化学療法が行われ,経過観察中であるが,現在(術後1年6カ月)までのところ再発の徴侯はない.
