Abstract
Colonic metastasis of uterine cancer is rare and most metastatic tumors are detected after a lapse of less than several years following the initial operation. We have experienced a case of uterine cancer recurred together with the infiltration into the descending colon 15 years after the initial operation.
The patient was a woman in her fifties who had undergone hysterectomy for uterine cancer, followed by irradiation therapy for the pelvis and periaortic area. Fifteen years after the operation, she was seen at a neighboring hospital because of left lateroabdominal pain, and was detected to have a tumor about 8 cm in diameter in the vicinity of the descending colon. She was referred to our hospital for the purpose of surgery, and underwent left hemicolectomy. The tumor was mainly situated at an extramural portion of the descending colon and revealed the same histological findings as the uterine cancer had. Accordingly colonic metastasis of uterine cancer was diagnosed.
Although colonic metastasis of uterine cancer is extremely rare, attention must be paid it as a possible diagnosis after surgery for uterine cancer. Further accumulation of clinical cases including data on long-term prognosis would be necessary.
