Abstract:

Primary ovarian borderline mucinous adenofibroma with mucinous adenocarcinoma is clinically rare. We report a case of a 47-year-old female patient who presented with a self-palpable pelvic mass that was gradually enlarging, accompanied by occasional lower abdominal pain. Transvaginal ultrasound revealed a medium-echogenic mass in the left adnexal region. The patient initially underwent complete tumor resection, followed by hysterectomy, right salpingo-oophorectomy, appendectomy, omentectomy, and regional lymphadenectomy at a higher-level hospital. Postoperative pathology confirmed the diagnosis as primary ovarian borderline mucinous adenofibroma with mucinous adenocarcinoma, stage ⅠA. The patient recovered well postoperatively with no signs of recurrence. Ovarian mucinous tumors are more commonly metastatic than primary. Diagnosis requires comprehensive evaluation based on clinical history, imaging examination, surgical exploration, gastrointestinal endoscopy, and immunohistochemical findings. A definitive diagnosis can only be made after excluding metastasis from tumors of the digestive system, endometrium, cervix, and other sites. Surgery is the primary treatment modality.
