腹腔鏡下手術後に診断された卵巣明細胞境界悪性腫瘍の1例

抄録

  Ovarian clear cell borderline tumors are extremely rare, accounting for less than 1% of all borderline ovarian malignancies. The preoperative diagnosis of ovarian borderline malignancy is difficult in some cases, and although the number of cases diagnosed incidentally after laparoscopy is increasing, the optimal treatment for each histological type is unclear. In this case report, we describe a 65-year-old woman who was diagnosed with a cystic ovarian clear cell borderline malignancy without adenofibromatous components after laparoscopy. She presented at our hospital due to an abnormal medical examination, and an MRI revealed a polycystic lesion in the left appendage area. No obvious malignant findings were observed, and laparoscopic bilateral salpingo-oophorectomy was performed. The pathology was determined to be cystic ovarian clear cell borderline malignancy. No additional postoperative treatment was given, and the patient was carefully monitored and has not experienced postoperative recurrence for 1.5 years.
