Rationale: Ovarian or adnexal tumors are very rare in patients below the age of 18 years, most of them being functional cysts, only 10% being malignant. We report 3 cases of ovarian tumors with the aim of revealing the particularities regarding the diagnosis and management of benign and malignant ovarian tumors in pediatric patients.
Patient concerns: The 1st case, a 9-year-old girl presented for diffuse abdominal pain, distended abdomen and rapid increase in abdominal volume. The 2nd case describes a 13-year-old female patient admitted for acute abdominal pain and nausea, and the 3rd one was an 18-year-old female teenager who presented for distended abdomen, intermittent diffuse abdominal pain and rapid increase in abdomen volume.
Diagnoses: The abdominal ultrasound revealed in all 3 patients suggestive signs for ovarian tumors.
Interventions: The 1st patient underwent laparotomy with adnexectomy, and the histopathological exam showed the diagnosis of dysgerminoma. The 2nd patient underwent laparoscopy with adnexectomy, and the histopathological exam revealed a borderline tumor. The 3rd patient benefited by a laparotomy with left ovariectomy, and the histopathological exam pointed out a mature teratoma.
Outcomes: The outcome was favorable in all 3 cases, but the patients with dysgerminoma and mature teratoma were further referred to the oncologist for proper assessment.
Lessons: Laparoscopy may represent the first choice for uncomplicated ovarian masses. The diagnosis and the therapeutic plan must be based on symptoms, pelvic ultrasound, the time of menarche and the potential serum markers.
