Abdominal pain- MedGen UID:
- 7803
- •Concept ID:
- C0000737
- •
- Sign or Symptom
An unpleasant sensation characterized by physical discomfort (such as pricking, throbbing, or aching) and perceived to originate in the abdomen.
Melena- MedGen UID:
- 7523
- •Concept ID:
- C0025222
- •
- Pathologic Function
The passage of blackish, tarry feces associated with gastrointestinal hemorrhage. Melena occurs if the blood remains in the colon long enough for it to be broken down by colonic bacteria. One degradation product, hematin, imbues the stool with a blackish color. Thus, melena generally occurs with bleeding from the upper gastrointestinal tract (e.g., stomach ulcers or duodenal ulcers), since the blood usually remains in the gut for a longer period of time than with lower gastrointestinal bleeding.
Gastric adenocarcinoma- MedGen UID:
- 82961
- •Concept ID:
- C0278701
- •
- Neoplastic Process
An adenocarcinoma arising from the stomach glandular epithelium. Gastric carcinoma often produces no specific symptoms when it is superficial and potentially surgically curable, although up to 50% of patients may have nonspecific gastrointestinal complaints such as dyspepsia.
Polyposis of gastric fundus without polyposis coli- MedGen UID:
- 357403
- •Concept ID:
- C1868001
- •
- Neoplastic Process
Multiple polyps in the acid-secreting mucosa of the gastric body and fundus. Fundic gland polyps (FGP) are usually 1 to 5 mm in size, though larger polyps have been found. FGPs are typically sessile, shiny, translucent, pale to pinkish in color (resembling the surrounding mucosa), and often exhibit tiny surface blood vessels. These polyps have characteristically been observed to chunk off or detach entirely at the base when removed with cold forceps, in contrast to other types of gastric polyps.
