Case report
A 62-year-old white woman was diagnosed with infiltrating ductal carcinoma by stereotactic core biopsy. The patient underwent mastectomy and sentinel lymph node biopsy. Lymph node metastases were found in 2 sentinel lymph nodes, and a completion axillary dissection was performed. The tumor measured 3.5 cm, with skin and dermal lymphatics invasion that was estrogen receptor/progesterone receptor (ER/PR) positive and HER-2/neu negative. Thirteen of 16 lymph nodes were involved with metastatic
Discussion
Although multiple primary malignancies are not unusual, the incidence of cancer-to-cancer metastasis is very uncommon.1, 2 There have been <60 cases of metastases from cancer to benign tumors1 and only 47 cases of cancer-to-cancer metastases.1, 3, 4 Most of these metastases were found after death. There are no previous reports of breast cancer that was metastatic to a resected RCC.
RCC is the most common tumor found to coexist with other malignancies.1 Rabbani et al5 reported a 27.4% incidence
