Brenner tumor, borderline malignancy

Last edited: 4/16/2026

Overview

Brenner tumors, classified as borderline malignancies, are uncommon ovarian neoplasms characterized by their unique histological features, including hobnail cells, and typically present with symptoms related to pelvic mass or hormonal effects 1.

Diagnosis

  • Histopathological examination remains the gold standard for diagnosing Brenner tumors 1.
  • Immunohistochemistry may aid in distinguishing Brenner tumors from other ovarian neoplasms 1.
  • Intraoperative assessment using ionization mass spectrometry (IMS) coupled with ultrasonic scalpel could potentially offer real-time pathological insights, though further validation is needed 1.
  • Management

  • Surgical resection, typically via laparoscopy or laparotomy, is the primary treatment modality 1.
  • Adjuvant therapy is generally not required for benign or borderline Brenner tumors 1.
  • Close follow-up is essential post-surgery to monitor for recurrence or complications 1.
  • Special Populations

  • No specific management guidelines differing for pregnancy, pediatrics, elderly, or comorbid conditions are provided in the given abstracts 1.
  • Key Recommendations

  • Confirm diagnosis primarily through histopathological examination with immunohistochemistry as supportive 1 (Evidence: Moderate).
  • Employ surgical resection for definitive treatment, considering minimally invasive approaches when feasible 1 (Evidence: Moderate).
  • Implement close postoperative surveillance to detect recurrence or new complications 1 (Evidence: Expert opinion).
