Abstract
INTRODUCTION: Differentiating between primary and secondary ovarian cancer can be a difficult task. In hereditary conditions breast malignancies and primary ovarian cancer often coexist.
PRESENTATION OF CASE: We present a 45-year-old patient with an ovarian mass two years after the diagnosis of a lobular, triple negative breast carcinoma. There was concern whether the lesion represented a metachronous ovarian cancer or a metastasis of the lobular carcinoma. The final histological examination showed a metastatic lesion, deriving from the lobular breast carcinoma, as evidenced by the immunohistochemical profile; nevertheless, there were changes in hormonal receptor expression in the metastatic lesion compared to the primary, triple negative tumor. The patient underwent genetic testing for BRCA1 and BRCA2 mutations and was negative. In the adjuvant setting the patient received 6 cycles of chemotherapy with carboplatin and paclitaxel; eighteen months later, the patient remains without disease recurrence.
DISCUSSION AND CONCLUSION: This case report highlights the role of imaging, histology and predominantly immunohistochemistry as valuable tools in the assessment of ambiguous ovarian lesions after breast cancer.
