Synchronous primary ovarian tumours in postmenopausal women: A rare case report and literature review

The reported incidence of synchronous primary cancers of genital tract is 1-2%, among this synchronous primary ovarian tumour is rarest. Herein, a postmenopausal woman, who had previously undergone abdominal hysterectomy, presented with vague lower abdominal pain persisting for six months. A computed tomography scan confirmed the presence of an 8.1 x 8.2 cm cyst on her right ovary. Despite her CA125 levels being normal, she was scheduled for laparoscopic cystectomy. During the surgery, the left ovary was found to be enlarged, prompting bilateral salpingo-oophorectomy. Histological analysis revealed a serous cystadenoma in the left ovary and a mucinous cystadenoma in the right ovary.Most reported synchronous ovarian tumors are malignant, with only a few cases of benign synchronous ovarian tumors documented in the literature. Early diagnosis and reporting of such cases are crucial for improving our understanding of synchronous ovarian neoplasms, which can impact management strategies and help prevent complications.
