Paraovarian tumor of borderline malignancy is rare. Only 13 cases in Japan, including the present cases, and 40 cases overseas have been reported. We report two cases of paraovarian tumor of borderline malignancy. Case 1: A 38-year-old woman was found to have a right ovarian cyst. Transvaginal ultrasonography showed a unilocular cystic tumor and a solid part of 8 mm in diameter within the tumor. Malignancy could not be ruled out, therefore the laparotomy was performed. The tumor was paraovarian tumor. Intraoperative rapid histological diagnosis was made and the patient was diagnosed with a serous borderline tumor. There has been no recurrence 1 year after surgery. Case 2: A 30-year-old woman was found to have a right hydrosalpinx, or an ovarian cyst, with a solid part inside. Transvaginal ultrasonography showed the solid part within the tumor was 14 × 9 mm. Laparoscopic surgery was performed and we diagnosed the tumor as paraovarian cyst. Histological diagnosis was mucinous borderline tumor. There has been no recurrence 11 months after surgery.
交界性恶性卵巢旁肿瘤较为罕见。在日本，包括本病例在内仅有13例报告，在海外有40例报告。我们报告两例交界性恶性卵巢旁肿瘤。病例1：一名38岁女性被发现右侧卵巢有囊肿。经阴道超声检查显示为单房囊性肿瘤，肿瘤内有一个直径8毫米的实性部分。无法排除恶性可能，因此进行了剖腹手术。该肿瘤为卵巢旁肿瘤。术中进行了快速组织学诊断，患者被诊断为浆液性交界性肿瘤。术后1年无复发。病例2：一名30岁女性被发现右侧输卵管积水或卵巢囊肿，内部有实性部分。经阴道超声检查显示肿瘤内实性部分为14×9毫米。进行了腹腔镜手术，我们将该肿瘤诊断为卵巢旁囊肿。组织学诊断为黏液性交界性肿瘤。术后11个月无复发。
