Glossary for Rectal bleeding

Adenocarcinoid tumor: A rare type of tumor that occurs in the gastrointestinal tract and tends to metastasize. The symptoms are determined by the location of the tumors.
Aminophyllin - Teratogenic Agent: Experimental studies on rats indicate that the use of Aminophyllin during pregnancy may cause various harmful effects on the fetus. The likelihood and severity of symptoms may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at. The effect on human fetuses has not been conclusively determined.
Anal Cancer: Cancer (malignant) that develops in the tissues of the anus.
Anal fissure: Tear in the anal region.
Attenuated familial polyposis: A genetic condition characterized by the development of adenomatous polyps mainly in the colon and rectum. There may be hundreds or thousands of polyps and these polyps have a predisposition for becoming cancerous. The attenuated form of the condition is distinguished by the development of polyps in old age rather than during the first decades of life.
Bannayan-Zonana syndrome: A rare genetic disorder characterized by macrocephaly, intestinal polyposis, pigmentation of penis and benign tumor-like growths.
Bushmaster poisoning: The Bushmaster is a poisonous snake found in America.
Chancroid: An sexually transmitted disease caused by the Haemophilus ducreyi bacteria and is characterized by painful genital ulceration.
Colorectal Polyps: Polyp growths in the colon or rectum.
Constipation: Difficult or dry bowel movements
Crohn's disease: Crohn's disease causes inflammation of the digestive system. It is one of a group of diseases called inflammatory bowel disease. The disease can affect any area from the mouth to the anus. It often affects the lower part of the small intestine called the ileum.
Dilor - Teratogenic Agent: There is evidence to indicate that exposure to Dilor (a bronchodilator) during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
Diverticular Disease: Protrusions of the colon wall (diverticulosis) or their inflammation (diverticulitis)
Dyphylline - Teratogenic Agent: There is evidence to indicate that exposure to Dyphylline (a bronchodilator) during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
Enterocolitis: Serious type of intestinal infection
Familial polyposis - classical: An inherited condition where polyps develop in the lining of the gastrointestinal tract. The polyps are initially benign but may become malignant if untreated.
Familial polyposis, autosomal recessive: An inherited condition where polyps develop in the lining of the gastrointestinal tract. The polyps are initially benign but may become malignant if untreated. The autosomal recessive form of this condition is characterized by fewer polyps than in other forms (less than 100) and is due to mutations in a different gene.
Fissures: Any cleft or groove especially a deep fold in the cerebral cortex involving its entire thickness
GI hemorrhage: gastrointestinal hemorrhage describes every form of hemorrhage (loss of blood) in the gastrointestinal tract, from the pharynx to the rectum
Gastrointestinal bleeding: Internal bleeding in the digestive tract
Hemorrhoids: Swollen blood vessels around the anus.
Hereditary nonpolyposis colon cancer: A rare disorder characterized by the inherited predisposition to develop colorectal cancer as well as cancers in other locations, particularly near the bowel. Even though sufferers face an increased risk of various cancers it does not mean that they will actually develop the cancer.
Juvenile polyposis of infancy: A genetic inherited risk of developing gastrointestinal tumors. The condition is characterized by gastrointestinal polyps which have a high risk of eventually becoming malignant. The polyps can cause gastrointestinal symptoms even if they aren't malignant.
Juvenile polyposis syndrome, infantile form: A genetic inherited risk of developing gastrointestinal tumors. The condition is characterized by gastrointestinal polyps which have a high risk of eventually becoming malignant. The polyps can cause gastrointestinal symptoms even if they aren't malignant.
Lufyllin - Teratogenic Agent: There is evidence to indicate that exposure to Lufyllin (a bronchodilator) during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
Lynch syndrome I: A rare disorder characterized by the inherited predisposition to develop colorectal cancer which usually occurs at a younger age than non-inherited forms. Type I differs from Type II in that there is an increased risk of colorectal cancers but not necessarily other cancers.
Lynch syndrome II: A rare disorder characterized by the inherited predisposition to develop colorectal cancer in the colorectal which usually occurs at a younger age than non-inherited forms. Type II differs from type I in that there is an increased risk of cancers in various parts of the body as well as colorectal cancer.
Lynch syndrome type I: Lynch syndrome is a rare disorder.The estimated proportion of all Colorectal cancers that are caused by Lynch syndrome depends on how this syndrome is defined, with traditional definitions being based on family history and age of onset. It is also known as hereditary nonpolyposis colorectal cancer syndrome(HNPCC). The syndrome is classified as Type I in the absence of extracolonic cancers and Type II if these are present.
Lynch syndrome type II: Lynch syndrome is a rare disorder.The estimated proportion of all Colorectal cancers that are caused by Lynch syndrome depends on how this syndrome is defined, with traditional definitions being based on family history and age of onset. It is also known as hereditary nonpolyposis colorectal cancer syndrome(HNPCC). The syndrome is classified as Type I in the absence of extracolonic cancers and Type II if these are present.
Microscopic collagenous colitis: Microscopic collagenous colitis refers to inflammation of the colon that is only visible when the colon's lining is examined under a microscope. The appearance of the inner colon lining in microscopic colitis is normal by visual inspection during colonoscopy or flexible sigmoidoscopy.
Microscopic lymphocytic colitis: Microscopic lymphocytic colitis refers to inflammation of the colon that is only visible when the colon's lining is examined under a microscope. The appearance of the inner colon lining in microscopic colitis is normal by visual inspection during colonoscopy or flexible sigmoidoscopy.
Microscopic ulcerative colitis: Microscopic ulcerative colitis refers to inflammation of the colon that is only visible when the colon's lining is examined under a microscope. The appearance of the inner colon lining in microscopic colitis is normal by visual inspection during colonoscopy or flexible sigmoidoscopy.
Nonpolyposis colorectal cancer, familial: A rare disorder characterized by the inherited predisposition to develop colorectal cancer. Even though sufferers face an increased risk of various cancers it does not mean that they will actually develop the cancer.
Oxcarbazepine - Teratogenic Agent: There is evidence to indicate that exposure to Oxcarbazepine during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
Pancytopenia: A term used to describe a lack of all of the different types of blood cells - red and white blood cells and blood platelets. Cancer, infections and toxins are some of the causes of pancytopenia. Symptoms depend on the severity of the deficiency.
Pelvic lipomatosis: A rare disorder where benign fatty growths develop in the pelvic area. Mainly occurs in obese, hypertensive, black males during old age. The main symptoms of the disorder tend to be related to compression of various genitourinary organs by the abnormal mass.
Proctitis: A chronic inflammatory disease of the rectum which causes bloody diarrhea.
Rambaud-Galian syndrome: A very rare syndrome characterized by the progressive deposition of a substance called hyaline in blood vessels of the digestive tract and kidneys. Calcification of the brain is also present.
Rectosigmoid neoplasm: A tumor that originates in the upper rectal area or sigmoid colon. The tumor may be benign or cancerous.
Turcot syndrome: A rare inherited disorder characterized by benign growths on the inside of the gastrointestinal tract and central nervous system tumors.
Ulcerative colitis: Ulcerative colitis (Colitis ulcerosa, UC) is a form of inflammatory bowel disease (IBD). Ulcerative colitis is a form of colitis, a disease of the intestine, specifically the large intestine or colon, that includes characteristic ulcers, or open sores, in the colon.
Vulvar cancer: Cancer (malignant) that develops in the tissue of the vulva.
