| The lesion appeared to be submucosal with an intact submucosa and muscularis propria interface. |
|
| The submucosa, muscularis propria and adventitia of the esophagus were normal. |
|
| It is generally confined to the submucosa, muscularis, and serosal layers, making endoscopic diagnosis difficult. |
|
| The tubular esophagus exhibits the typical structure of the gastrointestinal tract with an prominent muscularis mucosae and muscularis propria. |
|
| Tumors are considered invasive if they extend through the muscularis layer and into the submucosa. |
|
| About 500 mg of the tissue of the uterus near red isthmus, including the mucosa, muscularis and outer serosa was powdered under liquid nitrogen. |
|
| Large vascular spaces were observed to be deep in the hemorrhoid, separated from the surface by connective tissue and the muscularis mucosae. |
|
| Stomach specimens from normal control rats showed normal histological structures of the mucosa, submucosa as well as the muscularis. |
|
| The tumor invaded through the muscularis propria into pericolorectal fat tissues. |
|
| The submucosa contains the larger blood vessels that send branches to the mucosa, muscularis externs, and serosa. |
|
| The peritoneal aspect of the muscularis is invested with serosa. |
|
| Upon gross and microscopic pathologic examination, the tumor was character ized as an abdominal fibromatosis involving the small bowel serosa and muscularis propria. |
