Study Notes
Classification of Bowel Neoplasms (WHO 5th Edition, 2019)
- The classification includes various types of benign and malignant tumors in the bowel.
- Benign epithelial tumors and precursors include hyperplastic polyps, serrated dysplasia, adenomatous polyps, tubular adenomas, villous adenomas, and tubulovillous adenomas.
- Gastrointestinal stromal tumors and adipose tissue and (myo)fibroblastic tumors are also classified.
- Malignant epithelial tumors include adenocarcinoma, adenoma-like adenocarcinoma, micropapillary adenocarcinoma, mucinous adenocarcinoma, poorly cohesive carcinoma, signet ring cell carcinoma, medullary adenocarcinoma, adenosquamous carcinoma, carcinoma with sarcomatoid component, and undifferentiated carcinoma.
- Mesenchymal tumors, such as inflammatory myofibroblastic tumor, desmoid fibromatosis, solitary fibrous tumor, lipoma, inflammatory fibroid polyp, plexiform fibromyxoma, leiomyoma, leiomyosarcoma, rhabdomyosarcoma, haemangioma, and glomus tumor, are also included.
- Neural tumors like schwannoma, granular cell tumor, perineurioma, ganglioneuroma, and ganglioneuromatosis are part of the classification.
- Site-specific hematolymphoid tumors, including MALT lymphoma, duodenal-type follicular lymphoma, enteropathy-associated T-cell lymphoma, and intestinal T-cell lymphoma, are categorized.
- Haematolymphoid tumors occurring with some frequency in the digestive system, such as diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, Burkitt lymphoma, plasmablastic lymphoma, and posttransplant lymphoproliferative disorders, are included.
- Neuroendocrine tumors are classified based on grade, including grade 1, grade 2, grade 3, L cell tumor, glucagon-like peptide-producing tumor, PP/PYY-producing tumor, and enterochromaffin cell carcinoid.
- Tumors of uncertain differentiation, such as hematolymphoid tumors, PEComa, synovial sarcoma, and gastrointestinal clear cell sarcoma/malignant gastrointestinal neuroectodermal tumor, are also categorized.
- Other tumors of the digestive system, including mucosal melanoma, serotonin-producing carcinoid, germ cell tumors, neuroendocrine carcinoma, and digestive system metastases, are included.
- The simplified classification of bowel neoplasms includes categories for epithelial tumors (benign and malignant), neuroendocrine tumors, mesenchymal tumors, and others.
