Massive intra-abdominal recurrence after robotic-assisted radical cystectomy: A case report and critical appraisal of literature.

RARC is a safe and feasible alternative to open radical cystectomy (ORC) with satisfactory operative time, little blood loss, and low transfusion rates. Despite this, RARC is associated with a low, but not neglectable, risk of atypical metastases like peritoneal implants and port-site metastasis. Although a small amount (7%) of RARC were performed in non-urothelial variants of bladder cancer, the sarcomatoid one can be related to a greater risk of atypical recurrence and special precaution should be taken to reduce potential causes of tumor seeding.
