A 75-year-old man was referred to our urology service with painless haematuria. The delayed phase on a subsequent computed tomography (CT) abdomen and pelvis showed a filling defect in the left renal pelvicalyceal system, suspicious for a transitional cell carcinoma. The patient underwent ureteroscopic biopsy suggestive of a papillary neoplasia, before progressing to a laparoscopic radical left nephrouretectomy. Final histology revealed a fumarate hydratase-deficient renal cell carcinoma with clear margins. The patient was subsequently referred for genetic counselling. © BMJ Publishing Group Limited 2021.
