Abstract
Mucinous tubular and spindle cell carcinoma (MTSCC) of the kidney is a rare type of kidney cancer. Accurate diagnosis depends on pathological examination. A huge left renal tumor was incidentally found by computed tomography (CT) examination of a 52-year-old lady. She underwent Laparoscopic radical left nephrectomy. The postoperative pathological diagnosis is Mucinous tubular and spindle cell carcinoma. Eight months later, she showed no signs of recurrence.
