Infected, giant borderline ovarian tumor: A case report

Gigantic borderline ovarian cancer, also known as giant borderline ovarian tumor, is a rare subtype of borderline ovarian cancer. This type of ovarian cyst can be associated to various complication, including superinfection.

We present the case of a 30-year-old woman who sought medical attention due to chronic abdominal pain and a rapid increase in abdominal girth over the past four months. Pelvic ultrasound and pelvic magnetic resonance imaging (MRI) revealed an abdominal-pelvic mass of 27 ∗ 12 cm. The tumoral markers were elevated. During her hospitalization, she developed a fever along with abdominal pain and biological inflammatory syndrome. Surgical intervention a 30-cm-long solid cystic mass located on the right ovary, accompanied by moderate ascites. The surgical procedure included a right adnexectomy, omentectomy, and appendicectomy, with cytology performed. Postoperative antibiotics were administered, and the patient showed favorable clinical and biological progress. The anatomopathological examination confirmed a 35-cm borderline mucinous tumor with signs of infection.

Giant borderline ovarian tumor is characterized by the presence of an ovarian mass measuring at least 10 cm in diameter. Infectious complications are rare, and their clinical features usually mimic those of a peritonitis. Treatment is based on antibiotics and chirurgical removal of the tumor based on the FIGO classification along with peritoneal biopsies and cytology.

This study explores the diagnosis, treatment, and prognosis of infected giant borderline ovarian tumors.
