An 80-year-old male complained of lower abdominal pain and tarry stool, in January, 2004 on colonoscopy, a type 2 tumor was noted in the transverse colon. A diagnosis of adenocarcinoma (Group V) was made based on the histopathology. On computed tomography (CT) images, in addition to liver metastasis and lymph node metastasis, left renal hydronephrosis was found. The patient was seen by the urological service and renal cell cancer was diagnosed. Thus, the patient presented with two independent cancers. The patient refused surgical treatment and was not seen for 5 months. He received neither anticancer treatment nor any medications. In august, 2004, repeat colonoscopy was done, and the IIc lesion was no longer visible, a biopsy was done at the site where the lesion had been located, and on pathology, no cancer cells were noted. In August, 2004 the patient also had a right nephrectomy. Since that time, the colonic lesion was followed at regular intervals. In January, 2007, 30months after the disappear once of the lesion on colonoscopy and the right nephrectomy, the patient was alive with no signs of recurrence. This finding suggests that spontaneous regression can occur in patients with colonic.
