Abstract

Metastasis to the kidney in patients without evidence of a widespread nonrenal malignancy is rare since focal renal mass is more likely to represent a primary renal tumour. We present a case of 56-year-old man with renal mass presented with a pain in right lumber region for two months, accompanied by intermittent episodes of Malena. PET CT scan revealed large FDG avid hypo dense mass lesion with markedly increased metabolic activity is identified in the segment VI of the liver, right adrenal gland, upper and mid pole of the right kidney along with abdominal lymph nodes with infiltrating tumour thrombus. Biopsy of mass was consistent with Metastatic Carcinoma Immunohistochemical profile consistent with CK 7, CK 20, villin, CDX2, SA-B2 positive in tumour cells whereas MUC5AC and Hep-Par-1 were negative, favouring lower gastrointestinal tract. He was treated with Fluorouracil and Oxaliplatin based chemotherapy protocol in combination with Bevacizumab with a palliative intent.
