Answer: Cobblestone
Explanation:
Crohn's disease can be defined as an inflammatory bowel disease which may affect the segment of the gastrointestinal tract that covers the mouth to the anus. This disease is characterized by the formation of lesions in the colon as well as in the bowel typically in the submucosal layer.
The submucosal layer of the bowel takes the appearance of the cobblestone due to formation of the fissures and crevices also surrounded by the submucosal edema.
A tumor is an abnormal mass of tissue, which doesn't necessarily mean that you have cancer. Tumors can be benign, not cancerous, or they can be malignant, pre-cancerous. Another name for a tumor is a neoplasm.
