Pigmentation Of The Mucosa is the result of numerous small hemorrhages or occurs as a part of a general discoloration often seen in chronic malaria. The mucosa is of a dark, slaty discoloration.

Calcification of the stomach in small areas has sometimes been found in certain poisonings, such as bichlorid of mercury, that are accompanied by rapid absorption of lime salts from the bones. Particles of calcium carbonate are found in the interstitial tissue.

Gastromalacia is a condition of softening of the stomach walls due to post-morten changes resulting from the action of the gastric juices. Is most marked when there is hyperacidity and in that part of the stomach that has been most dependent, the portion that contained the stomach contents. If the organ was anemic, the mucous membrane appears pale gray in color and somewhat gelatinous in consistency. If congestion was present, the mucosa will be dark brown. This is particularly marked along the veins, the hemoglobin being transformed into hematin. Sometimes perforation may occur, but this can be recognized readily, as there will be no local inflammatory reaction or peritonitis.

Gastroptosis

Gastroptosis is a downward displacement of the organ, either acquired or congenital, and is very frequently a part of a general displacing or splanchnoptosis of all the abdominal viscera. Is quite commonly due to dilatation following pyloric obstruction.
