Primary malignancies of different organs can occur in the same patient. If two or more primary malignancies are detected in the same patient at the same time, or within interval of two months, they are known as synchronous malignancies. Metachronous malignancies arise anew in some different organ and detected later. Synchronous breast and renal cell carcinoma (RCC) can occur rarely. We present a case of patient of breast cancer with synchronous primary malignancy of kidney. A 55 year old female patient presented with one month history of painless left breast lump. On CT scan, there was an incidental finding of right renal mass. On histopathological examination, the mastectomy specimen was reported as Infiltrating ductal Carcinoma along with in situ component and comedo necrosis. The nephrectomy specimen was reported as Renal Cell Carcinoma- Clear Cell Type. (Fuhrman grading- 2/4). The study of synchronous malignancies may provide important evidences not only for clinical evaluation and further treatments of these tumours, but also provide clues for the aetiology, pathogenesis and the future management of cancer including the development of effective screening and surveillance protocols, with the goal to treat patients effectively.
