Objective:

To present a case of synchronous primary breast carcinoma and metastatic high-grade serous ovarian carcinoma, highlighting the diagnostic challenges, treatment approaches, and the significance of genetic factors in management.

Approach:

Key Findings:

• Breast metastasis from high-grade serous ovarian carcinoma is rare, with only 0.03%-0.6% of malignant breast neoplasms being metastatic, underscoring the need for careful diagnostic evaluation.
• The case illustrates the importance of distinguishing between primary breast carcinoma and metastatic ovarian carcinoma using morphology and immunohistochemistry, with implications for treatment strategies.
• The patient had a pathogenic BRCA mutation and HRD-positive status, which significantly influenced treatment decisions and highlights the importance of genetic assessment in similar cases.

Interpretation:

The coexistence of primary breast carcinoma and metastatic ovarian carcinoma presents significant diagnostic challenges, necessitating a multidisciplinary approach that includes genetic assessment.

Limitations:

• The rarity of the case limits the generalizability of findings, and potential biases in case selection should be acknowledged.
• Long-term outcomes and efficacy of treatment strategies in similar cases remain to be established.

Conclusion:

This case emphasizes the need for careful diagnostic evaluation in patients with breast lesions and known ovarian carcinoma, and the importance of genetic assessment in guiding treatment.
