Introduction: In patients with female genital tract cancers, during treatment, differentiating between a tumor recurrence and a benign phenomenon is of great importance. This study aimed to report a case of retroperitoneal lymphocele in a patient with primary ovarian cancer. Case Presentation: A 49-year-old woman diagnosed with papillary serous ovarian carcinoma was referred to the oncology clinic in 2017. She was treated with an optimal surgical staging and underwent adjuvant chemotherapy. After 3 courses of chemotherapy, she complained of a large abdominal mass in the umbilical area. Evaluating the mass confirmed retroperitoneal lymphocele, which was treated with a non-surgical therapy. Conclusions: Pelvic mass in patients with previous ovarian cancer is not necessarily due to the recurrence of the tumor and the possibility of lymphocele diagnosis should be considered. Since preventing the causes of lymphocele is very difficult, it is only necessary to carefully follow-up and provide essential consultations for highrisk patients.
