Primary Serous Cystadenocarcinoma of Broad Ligament: A Case Report with Laparoscopic, Histopathologic and Immunohistochemical Findings

Abstract

An 86-year-old Japanese woman underwent an examining laparoscopy for removing the huge pelvic tumor. At laparoscope examination, the cystic tumor was found within the left broad ligament, while the ovaries, fallopian tubes and uterus showed almost normal appearance. The tumor was removed together by total laparoscopic hysterectomy and bilateral salpingo-oophorectomies after the suction of serous content in the broad ligament. Cytological findings of the ascites suggested serous carcinoma. The resected ovaries and fallopian tubes were grossly and histologically normal. Histological examination of the solid part of broad ligament tumor, closely next to the fallopian tube, revealed a serous adenocarcinoma. Immunohistochemically, the tumor cells were strongly positive for CK7, WT-1,
