Diseases Associated with Gastrointestinal and Extra-Intestinal Cancers - Page 2
FAP may present with some extraintestinal manifestations like bone tumors called osteomas, dental abnormalities (unerupted teeth, congenital absence of one or more teeth, supernumerary teeth, dentigerous cysts and odontomas), congenital hypertrophy of the retinal pigment epithelium (CHRPE), desmoid tumors, and extracolonic cancers (thyroid, liver, bile ducts and central nervous system).
Familial gastric cancer, cancer of the stomach, hereditary diffuse gastric cancer and other germline genetic gastric cancers are associated with cancer elsewhere in the GI tract; so also, are pancreatic cancers and hereditary pancreatitis.
Helicobacter pylori (H. Pylori) and diffuse gastritis are associated with cancer of the stomach. H. Pylori, a comma shaped bacillus, infects the stomach, mainly in areas of poor sanitation; and manifests the symptoms of acid peptic disease.
