She was admitted, studied and diagnosed a giant tumor of gynecological viscus. It was decided to perform laparotomy. During surgery, it was observed that the tumor corresponded to the urinary bladder, so an urologist was requested. The operation continued and a big tumor of wide base was found that occupied the posterior and lateral left part of the urinary bladder, with necrosis areas of whitish color and a little soft consistency. The right ureteral meatus was catheterized, the left was not visible, and exeresis of the tumor was performed. A Foley catheter no. 20 was left by cystotomy. The urinary bladder was closed in 2 planes, and the abdominal cavity was checked. Normal uterus, ovaries, colon, intestine and liver were found. In the histological study, it was proved that the tumor was a pleomorphic rhabdomyosarcoma. Its evolution was followed and interconsultations were made with the oncology service for further treatment.(AU)
