: Tumors arising from hormone-producing cells. These are classified into well-differentiated Neuroendocrine Tumors (NETs) and poorly differentiated Neuroendocrine Carcinomas (NECs) .

: The GI tract is the most common extranodal site for lymphomas. Common types include Diffuse Large B-Cell Lymphoma (DLBCL) and MALT lymphoma . 2. Pre-Neoplastic Lesions and Polyps

Neoplasms in the GI tract are broadly categorised based on their tissue of origin:

Neoplastic gastrointestinal pathology: an illustrated guide - Gut

: The most frequent mesenchymal tumor.

: Non-epithelial tumors of the GI wall.

Many GI cancers develop from precursor lesions, often appearing as polyps:
