Background: Metastasis of extragenital neoplasms to the uterus are rarely encountered, and usually occur as a manifestation of advanced disease. Lobular carcinoma is the most common type of breast cancer that metastasizes to the uterus. Case Report: We report on a 56-yearold woman who 3 years previously was diagnosed with invasive lobular carcinoma of the breast and was treated with surgery followed by chemotherapy and radiotherapy. While the patient was on adjuvant anastrozole therapy for 2 years, she complained of vaginal bleeding. Because of endometrial thickening and a uterine leiomyoma detected during abdominal ultrasonographic ex-amination, a total hysterectomy with bilateral salpingooophorectomy was performed. Histopathologic examination of the specimens revealed carcinoma infiltration of the myometrium, endometrium, cervix, uterine tube, and left ovary. Immunohistochemical staining of tumoral cells with pancytokeratin and gross cystic disease fluid protein (GCDFP-15) proved the diagnosis of metastatic lobular breast carcinoma to the uterus. Conclusion: To our knowledge, this is the second case of lobular breast carcinoma metastasized to the uterus under anastrozole therapy. In women with lobular breast cancer under adjuvant anastrozole therapy, who present with vaginal bleeding, uterine metastasis of lobular carcinoma should be considered in the differential diagnosis.

“…To our knowledge, there are only 11 cases in the literature of endometrial polyp involvement by a metastatic neoplasia: one case of cutaneous melanoma [3] and breast cancer in the others [4][5][6][7][8][9][10][11][12]. Of these latter, seven patients were reported to be receiving adjuvant endocrine treatment with tamoxifene at the time of the diagnosis [6,[8][9][10][11][12].…”

Metastatic breast ductal carcinoma detected in a toremifene-associated endometrial polyp: case report and literature review

et al. 2009

Uterine metastases are rare events, but when they occur, the first extragenital neoplasm responsible is breast carcinoma. Toremifene, used in breast cancer hormonotherapy, has a partial estrogenic agonist effect in the endometrium, responsible for potential abnormalities, like polyps. A 53-yearold woman, receiving toremifene due to previously excised breast ductal carcinoma, presented with endometrial thickness during an abdominopelvic ultrasound follow-up. Hysteroscopy revealed an endometrial polyp, which was removed. Microscopic examination showed infiltration by a malignant ductal pattern neoplasm, with signet ring cells. The patient underwent hysterectomy and bilateral salpingo-oophorectomy. The final pathological diagnosis was metastatic breast carcinoma to the endometrium and cervix. This is the first reported case of breast metastases detected in a toremifene-associated endometrial polyp.

The potential role of HER2 upregulation in metastatic breast cancer to the uterus: a case report

Key Clinical MessageAbnormal uterine bleeding in a patient on maintenance hormonal therapy for breast cancer should raise concern for endometrial abnormalities including rare uterine metastasis from the breast. Hormonal receptor profile changes in metastatic lesions favoring human epidermal growth factor receptor 2 (HER2) overexpression may be involved in the pathogenesis of metastasis to the uterus.
