Ovarian clear cell carcinoma with bilateral breast metastasis

Abstract

Clear cell carcinoma of ovary (CCCO) is a rare subtype of epithelial ovarian tumors that is associated with poorer prognosis due to relative chemoresistance and higher chances of recurrence. Metastasis to the breast is extremely rare. Here, we report a case of ovarian cancer with metastasis to bilateral breasts. A 46-year-old female presented with pain abdomen and mild distension. Examination revealed pelvic mass and bilateral breast lumps. Staging laparotomy and fine-needle aspiration cytology from bilateral breast lumps were done. Histopathology revealed CCCO with metastasis to bilateral breasts. Due to the rarity of CCCO, there are no standard guidelines for management. The patient should be subjected to maximum cytoreduction and chemotherapy. Metastasis to the breast from ovary can occur either due to retrograde lymphatic or hematogenous spread that confers a worse prognosis. Hence, in a patient with breast mass especially with a history of malignancy, breast metastasis should be differentiated from primary breast cancer.
