| polyp | 1. <pathology> Growth, usually benign, protruding from a mucous membrane. 2. <plant biology> The sessile stage of the Cnidarian life cycle, the cylindrical body is attached to the substratum at its lower end and has a mouth surrounded by tentacles bearing nematocysts at the upper end, Hydra and the feeding polyps of the colonial Obelia are examples. (14 Oct 1997) |
| myomatous polyp | A polyp that consists of benign neoplastic tissue derived from nonstriated (smooth) muscle. Synonym: fleshy polyp. (05 Mar 2000) |
| cystic polyp | A pedunculated cyst. Synonym: hydatid polyp. (05 Mar 2000) |
| pulp polyp | hyperplastic pulpitis |
| Hopmann's polyp | <otolaryngology> A papillomatous overgrowth of the nasal mucous membrane. Synonym: Hopmann's polyp. (05 Mar 2000) |
| sessile polyp | Any form of polyp that has a relatively broad base. (05 Mar 2000) |
| hydatid polyp | A pedunculated cyst. Synonym: hydatid polyp. (05 Mar 2000) |
| hyperplastic gastric polyp | <radiology> Regeneration polyp, inflammatory polyp, most common type of gastric polyp (75-90%), histology: proliferated gastric mucosa with acute and chronic inflammatory infiltrates in lamina propria, location: randomly distributed in stomach, associated with, chronic atrophic gastritis, pernicious anaemia, findings: sharply delineated polyp with smooth circular border, Mexican hat sign: stalk seen en face overlying the head of the polyp, sessile/pedunculate; usually multiple, usually less than 1 cm, no contour defect in stomach (12 Dec 1998) |
| hyperplastic polyp | A benign small sessile polyp of the large bowel showing lengthening and cystic dilation of mucosal glands; also applied to non-neoplastic gastric mucosal polyp's. Synonym: metaplastic polyp. (05 Mar 2000) |
| nasal polyp | <otolaryngology> A projection of the mucosa lining the nasal and paranasal sinuses that is rounded and elongated within the nasal cavity. A common cause for nasal airway obstruction in patients who suffer from allergic sinusitis. They are found more commonly in those with chronic allergic rhinitis or sinusitis. Large nasal polyps can interfere with nasal breathing and are often removed surgically to improve breathing and decrease chronic allergic symptoms. (27 Sep 1997) |

| duodenal polyp | Pedunculated growths in the lining of the duodenum (first part of the small intestine). (27 Sep 1997) |
| inflammatory polyp | A projecting mass of granulation tissue, large numbers of which may develop in ulcerative colitis; may become covered by regenerating epithelium. Synonym: inflammatory polyp. (05 Mar 2000) |
