Serous Carcinoma of the Peritoneum with Metastases to the Breast and Axillary Lymph Nodes].

Metastasis of peritoneal serous carcinoma to the breast and axillary lymph nodes is rare. We present a case of serous carcinoma of the peritoneum with metastases to the breast and axillary lymph nodes. A 72-year-old woman was diagnosed with Stage III peritoneal serous carcinoma in November 2009; she was treated with 6 courses of paclitaxel and carboplatin. In December 2015, she had a palpable mass(2×2 cm)and enlarged axillary lymph nodes. Mammography did not reveal any mass(C1)and ultrasonographic examination demonstrated a partially ill-defined hypoechoic mass with a diameter of 8.7× 7.1 mm. Cytological examination of the axillary lymph node revealed malignancy; breast carcinoma metastasis was suspected and the patient underwent breast-conserving surgery. Histopathological examination of the specimens(breast and axillary lymph nodes)revealed adenocarcinoma, and immunohistochemistry analysis showed that the specimens were CK7(+), CK20(-), CA125(+), PAX8(+), and GCDFP15(-). Taken together, the results indicated peritoneal serous carcinoma metastases to the breast and axillary lymph nodes. We report a case of serous carcinoma of the peritoneum with metastases to the breast and axillary lymph nodes.
