: Tumors arising from hormone-producing cells. These are classified into well-differentiated Neuroendocrine Tumors (NETs) and poorly differentiated Neuroendocrine Carcinomas (NECs) . Neoplastic Gastrointestinal Pathology
Neoplasms in the GI tract are broadly categorised based on their tissue of origin:
Many GI cancers develop from precursor lesions, often appearing as polyps: : The most common type, including adenocarcinomas (the

Neoplastic Gastrointestinal Pathology: A Diagnostic Overview Neoplasms in the GI tract are broadly categorised
Neoplastic gastrointestinal (GI) pathology involves the study and diagnosis of tumors arising within the digestive tract, ranging from the oesophagus to the rectum . This field is critical for determining whether a lesion is benign or malignant, grading its severity, and establishing a staging framework for clinical treatment. 1. Classification of GI Neoplasms
