Synchronous breast and kidney carcinomas are extremely rare with only 11 cases have been reported in the literature so far in the world. We present a case of a 40-year-old lady diagnosed with right invasive ductal cell carcinoma. During the workup of the patient, an incidental renal mass was identified. After appropriate investigations, the patient underwent a right modified radical mastectomy with a right partial nephrectomy. The patient recovered successfully and was put on regular follow-up post-discharge. We are reporting a case of synchronous presentation of carcinoma breast with RCC which is rare since in world literature, most of the multiple malignancies reported are metastasis/metachronous breast carcinoma with RCC. The aetiology of synchronous malignancy is complex, some primary tumours may not be symptomatic and detected in the routine metastatic workup, and this poses a challenge for the surgical team. Hence with the histopathological report and with the other clinical and radiological parameters, we made a final diagnosis of carcinoma right breast pT2N0M0 with synchronous renal cell carcinoma (RCC) pT1aN0M0. the patient was planned for adjuvant chemotherapy and advised regular follow-up.
