Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by a chronic type 2 inflammatory response in the paranasal sinuses. Group 2 innate lymphoid cells (ILC2) are potent innate immune cells that contribute to type 2 inflammation by producing cytokines such as IL-4, IL-5 and IL-13. There is increasing evidence suggesting that ILC2 ...Conventional endometrial, endocervical, or adenomyomatous pedunculated, or sessile lesion with histologic features diagnostic of polyp.

A polyp is a projection (growth) from the inner lining into the lumen (hollow center) of the colon or rectum. There are different types of polyps, which look different when seen with a microscope. Most polyps are benign (non-cancerous) growths, but cancer can start in some types of polyps. The gut-associated lymphoid tissue (GALT) system consists of scattered lymphoid cells in the lamina propria and organized lymphoid aggregates or follicles in the mucosa or submucosa [ 1 - 5 ]. GALT serves as part of both the immune system and the mucosal repair system of the gastrointestinal tract [ 1, 6 ].Sometimes cells in your body grow out of control, a process called mutation. Some of the abnormal cells can turn into polyps and other types of tumors. Tubular adenomas are often small -- less ...Polyp of colon.
