To present a case of synchronous bilateral breast cancer with different histological types and discuss the diagnostic and treatment challenges, emphasizing the rarity of such cases.
Key Findings:
The right breast lesion was invasive breast carcinoma with apocrine differentiation (triple-negative immunophenotype).
The left breast contained multifocal mucinous carcinoma (luminal-like immunophenotype).
At 31 months postoperatively, the patient remained disease-free with no signs of local recurrence or distant metastasis.
Interpretation:
Limitations:
The rarity of synchronous bilateral breast cancer cases limits generalizability due to the unique characteristics of each case.
Long-term outcomes beyond 31 months are not reported.
Conclusion:
This case illustrates the management of synchronous bilateral breast cancers with distinct histological types.
