* The gross appearance of colorectal [[Intestine Proliferative - Pathology #Adenocarcinoma|adenocarcinomas]]vary from pedunculated, particularly in the distal rectum, cobblestone, in particularly the middle rectum, and annular, also usually in the middle recutum, and may also have associations with tumour behaviour and prognosis.

* In cats, [[Intestine Proliferative - Pathology #Adenocarcinoma|adenocarcinomas]] have been reported to have been found in the ileum and ileocaecal region. Another study reports the jejunum to be the most common site.

* Metastasis occurs via lymphatic and vascular routes. For small intestinal [[Intestine Proliferative - Pathology #Adenocarcinoma|adenocarcinomas]] the most frequent sites of metastasis are the mesenteric lymph nodes. Other sites include the liver, kidneys, peritoneal cavity, omentum and lungs. Metastatic spread is commonly encountered at time of diagnosis.
