Metastatic Renal Cell Carcinoma Masquerading as a Breast Lumpa Clinical Insight Into a Synchronous Case of Oligometastatic Renal Cell Carcinoma

Abstract

Introduction: Renal Cell Carcinoma (RCC), a highly vascular tumor may present with rare metastasis at initial presentation. Synchronous breast metastasis from clear cell renal cell carcinoma is very rare and correlates with poor prognosis. In absence of any renal complaints, a breast lump can mimic a primary breast carcinoma or benign breast disease. A 55-year-old fema Case History: le, presented with a swelling in the right breast. Physical examination was suggestive of a benign swelling in view of well-dened margins, no lymphadenopathy, no skin changes. Fine needle aspiration cytology was done twice and was inconclusive. Tru-Cut biopsy revealed metastatic RCC. Mammography showed BIRADS-IV lesion and PET-CT revealed oligometastatic disease with breast and a small solitary lung metastasis. The patient underwent simultaneous right cytoreductive nephrectomy and lumpectomy. Early detection and surgical resecti Conclusion: on of limited metastatic disease is important, as the treatment instituted at an earlier stage when it is amenable to surgical resection improves the survival considerably
