What is a malignant intestinal tumor also known as?

A malignant intestinal tumor is most commonly referred to as a lymphosarcoma. Lymphosarcomas are malignant neoplasms that arise from lymphoid tissue, which can include the intestines among other locations in the body. These tumors are part of a broader category known as lymphoid neoplasms, which encompass a range of malignancies originating from lymphatic tissues.

While other types of tumors can occur in the intestines, such as carcinoid tumors, which are also malignant but arise from neuroendocrine cells, the term lymphosarcoma specifically denotes a malignant growth that is particularly associated with the lymphatic system. Additionally, benign adenomas, which are non-cancerous growths found in the intestinal tract, do not fit the description of a malignant tumor, making them an incorrect choice in this context. Thus, lymphosarcoma best represents the malignant intestinal tumor in question.
