Introduction/Background Breast cancer is the most common cancer affecting women. The prognosis of this disease depends on the occurrence of metastatic disease. In this case, surgical castration may be proposed as a therapeutic option. The discovery of a malignant ovarian lesion during or after treatment raises the question of whether it is of primary or secondary origin.

Methodology Retrospective study at the Mohammed VI center for cancer treatment CHU Ibn Rochd Casablanca, over a period spanning 10 years, from June 2013 to March 2022. The study included 76 patients with breast cancer who had undergone therapeutic bilateral oophorectomy and on whom a secondary lesion had been discovered incidentally.

Results 7 cases of malignant ovarian lesions. Bilaterality in 5 cases, 2 cases metastatic lesions involved only one ovary.

Conclusion The appearance of an ovarian metastasis, like any other secondary location, appears to be an element of severity in the history of breast cancer. The presence of an ovarian lesion challenges the gynaecologist and pathologist to predict whether a new ovarian cancer is primary, or secondary to a known primary.

Disclosures provide an overview of secondary ovarian lesions discovered incidentally on bilateral oophorectomy specimens performed as part of surgical castration in the treatment of breast cancer.
