title: Transitional cell carcinoma of ureter simulating left colonic malignancy-a rare case.
abstract: We reported a case of ureteric tumor, an uncommon disease presenting with colonic obstruction. This 52-year-old lady presented with history of colicky pain left lower abdomen for 5 months. Colonoscopy revealed circumferential nonnegotiable stricture at 25 cm from anal verge, and colonoscopic biopsy was inconclusive. Contrast-enhanced computed tomography (CECT) showed a growth involving sigmoid colon and left ureter with proximal left hydroureteronephrosis with nonfunctioning left kidney. Guided fine needle aspiration cytology (FNAC) showed features of an adenocarcinoma. The patient was operated with a diagnosis of carcinoma colon and underwent low anterior resection with left nephroureterectomy. Histopathology of resected specimen revealed ureteric transitional cell carcinoma with colon infiltration. She had smooth postoperative recovery.
