A Case in Which Metachronous Ovarian Metastasis Developed 9 Months after Surgery for Cecal Carcinoma Perforation and Peritonitis
Summary
The patient was a 78-year-old woman who underwent surgery for cecal carcinoma perforation and peritonitis(ileocecal resection and ileostomy)in January 2012. Liver metastasis was observed on the postoperative computed tomography(CT)scan and chemotherapy was performed. However, in October, a CT scan revealed a tumor, 9 cm in diameter, in the right ovary. Based on the results of a positron emission tomography(PET)-CT scan, this was suspected to be primary or metastatic ovarian cancer, and bilateral salpingo-oophorectomy was performed the following January. Histopathology and immunostaining indicated that this was a cytokeratin(CK) 20-positive and CK7-negative adenocarcinoma, and the patient was diagnosed with metastatic cecal carcinoma.
要旨
症例は78歳,女性。2012年1月に盲腸癌穿孔,腹膜炎にて手術(回盲部切除術,人工肛門造設術)施行。術後CTにて肝転移を認め,化学療法を行ったが10月のCTにて右卵巣に径9 cm大の腫瘤を認め,PET-CTでも原発性または転移性卵巣癌が疑われ,2013年1月に手術(両側付属器摘出術)施行。病理組織学所見では腺癌を認め,免疫染色ではcytokeratin(CK)7(-),CK20(+)であり,盲腸癌の転移と診断された。
