Single-port laparoscopic surgery as a useful diagnostic tool for primary ovarian lymphoma: a case report.

The preoperative diagnosis of ovarian lymphoma, a rare pathology, is often difficult. Consequently, laparotomy is usually performed under the presumptive diagnosis of ovarian cancer. In cases where the initial curative surgery for ovarian cancer is challenging, diagnostic laparoscopy is performed. Herein, we report a case in which single-port laparoscopic surgery effectively diagnosed primary ovarian lymphoma. A 55-year-old woman presented with abnormal uterine bleeding. PET-CT findings suggested ovarian cancer with multiple metastases. Single-port laparoscopic surgery was performed because curative surgery was deemed difficult. She had an uneventful recovery and was discharged on the fourth postoperative day. After the pathological diagnosis was made, she was referred to the hematology department for treatment. Diagnostic laparoscopy is recommended for advanced ovarian cancer to facilitate early postoperative treatment. This case highlights the utility of single-port laparoscopic surgery in the accurate diagnosis and early treatment of intraperitoneal malignancies.
