Metastatic ovarian serous carcinoma presenting as inflammatory breast cancer: a case report.

A 42-year-old woman presented with localized irritation, erythema and sharp pain in the one breast. After unsuccessful treatment for mastitis, an oncology consultation was obtained. A breast biopsy revealed an invasive carcinoma and a diagnosis of inflammatory breast cancer was made. The patient was treated with neo-adjuvant chemotherapy and subsequently underwent bilateral mastectomy. A total abdominal hysterectomy and bilateral salpingo-oophorectomy was also performed at the same time due to the presence of a pelvic mass. Morphologic and immunohistochemical examination of the specimens helped to clarify the correct diagnosis of primary ovarian carcinoma with widespread metastases to bilateral breasts.
