muscularis propria

It is characterized by deep folds into the muscularis propria.

Smaller tumors can usually be found to the muscularis propria layer of the intestinal wall.

Stage C1: Extending into muscularis propria but not penetrating through it.

The histologic findings of appendicits are neutrophils in the muscularis propria.

True diverticula involve all layers of the structure, including muscularis propria and adventitia.

Tumor invades through the muscularis propria into pericolorectal tissues.

Tumor invades deep muscularis propria (outer half).

The ova are initially deposited in the muscularis propria which leads to ulceration of the overlaying tissue.

Stage C2: Penetrating through muscularis propria.

If the muscularis propria escapes extensive damage, we assume that the impaired bowel propulsion is allowed to recover to some extent.

It is a true diverticulum, consisting of all 3 layers of the bowel wall which are mucosa, submucosa and muscularis propria.

Inflammation of the muscularis propria releases enzymes including collagenases which destroy the connective tissue of the bowel wall.

Similar ultrastructural features were present in the ileum and colon, with the most noticeable abnormalities present in the muscularis propria.

It invades the wall, infiltrating the muscularis mucosae, the submucosa and thence the muscularis propria.

In severe inflammation where the muscularis propria is infiltrated by phagocytic effector cells, profound dilatation may occur such as that seen in toxic megacolon.

These studies support our findings that clinically significant amyloid deposits in the muscularis propria are more likely in AL amyloidosis than in AA.

In comparing the AA, AL, and AH cases, we found an appreciable difference in the degree of amyloid deposits in the muscularis propria.

Table II shows the degree of amyloid deposition and destruction of organic structures in the muscularis propria, myenteric plexuses, and blood vessels of the small intestine.

Once massive amyloid dposits occur in the muscularis propria, this myopathy is thought to be an irreversible change because of the difficulty of elimination of this insoluble protein.

Once symptoms are present (e.g., dysphagia, in most cases), esophageal cancers have usually invaded the muscularis propria or beyond and may have metastasized to lymph nodes or other organs.

Studies on endoscopic ultrasound show slight trend toward thickening of the muscularis propria of the esophagus in nutcracker esophagus, but this is not useful in making the diagnosis.

In the most severe cases, transmural infarction with resulting perforation may be seen; after recovery, the muscularis propria may be replaced by fibrous tissue, resulting in a stricture.

The muscular coat (muscular layer, muscular fibers, muscularis propria, muscularis externa) is a region of muscle in many organs in the vertebrate body, adjacent to the submucosa membrane.

Extension into the muscularis propria (muscular layer of the esophageus) has meant a 20% 5YSR and extension to the structures adjacent to the esophagus results in a 7% 5YSR.
