Metastasis of Renal Carcinoma to ascending colon. A 50 year-old female with rectal bleeding and weight loss of more than 20 pounds. The patient had a negative barium enema , done elsewere, 4 months ago the patient had a negative barium enema , in another clinic. The patient underwent a unilateral nephrectomy, 3 years ago, due to renal carcinoma of the right kidney.

Metastasis of Renal Carcinoma to ASCENDING COLON . When the biopsy was taken an encapsulated tumor was observed. The tumorīs morphology was of a membrane-like capsule, which lead to the impression that the mass was not a typical carcinoma but of a different etiology.

The multilobulated tumor is observed. Bleeding is appreciated. During surgery, an invasive neoplastic tumor was found which extended from a displaced cecum, (due to prior nephrectomy) towards the lower border of the liver, without infiltrating that organ.
