Inter-pathologist reproducibility in classifying extraovarian implants in borderline serous ovarian tumor and low-grade serous carcinoma

Key Points

• Significant challenges exist in classifying non-invasive implants and low-grade serous carcinoma metastases among pathologists.
• In a diagnostic evaluation of multiple cases, pathologists showed variability in interpretation, affecting care.
• Focused on distinguishing between borderline serous tumors and low-grade serous carcinoma metastases, with an emphasis on accurate classification.
• Highlights the urgent need for consensus-based diagnostic algorithms to improve accuracy in pathology.
