Any form of unregulated growth in the<unk>  may cause<unk> . The exact etiology is unclear. However, risk factors may contribute to the formation of<unk> . There are four different types of<unk>  including inflammatory, hamartomatous, serrated, and adenomatous<unk> , which have different pathogenesis. Inflammatory<unk>  are non-neoplastic<unk>  that occur following intestinal inflammation, infections, or ischemia. Hamartomatous<unk> is an overgrowth of mature cells and connective tissue elements including smooth muscle, lamina propria, and cartilage, and fat. They are covered by a hypertrophic epithelium. Serrated<unk>  are different<unk>  which have variable malignant potential. They include hyperplastic, sessile serrated and traditional serrated<unk> . Hyperplastic<unk>  are the most common<unk> . Hyperplastic<unk> is infolding of the crypt epithelium that forms serration or saw-toothed appearance. Sessile serrated<unk>  are flask-shaped crypts, with dilatation and branching but not pedunculated. Traditional serrated adenomas are serrated<unk>  that are protuberant and pedunculated, which are located in left<unk> . Traditional adenoma also known as conventional<unk> , are developed throughout the<unk> . They are the most prevalent<unk>  that have malignant potential.
