A rare benign renal tumour presenting as polycythaemia in a teenage girl.
We present the case of a 15-year-old girl who presented with polycythemia. CT abdomen revealed an enhancing mass in the upper pole of her left kidney with features suggestive of renal cell carcinoma. She underwent a laparoscopic radical nephrectomy. Histology demonstrated a well circumscribed, focally encapsulated, round blue cell tumour showing areas of microcalcifications and numerous psammoma bodies. Imunostaining showed diffuse positive staining for CD 57. This was consistent with a diagnosis of metanephric adenoma a rare benign epithelial renal tumour.
