Pathology for Medical II Students Lab 1f Squamous Cell
Carcinoma of the Esophagus (62000-80713)
Slide 1
Gross: This is an example of
an ulcerated squamous cell carcinoma of the esophagus. It differs
from a benign peptic ulcer of the esophagus in that it is a much
larger lesion and rather than being sharply punched-out, it has
irregular borders. Note the perforation in the center. |
 |
Slide 2
Is a low power view of the
histologic section in your class set. (M = mucosa; Sm = submucosa;
Mp = muscularis propria). The intact mucosa is to the left of the
arrow; the ulcerated carcinoma (C) is to the right. |
 |
Slide 3
Is taken at the juncture (arrow
head) of the normal mucosa (M) and the ulcerated carcinoma (C) and
it shows another common feature of esophageal cancer. The gross
margins of the cancer are often misleading because the tumor
frequently spreads longitudinally in submucosal lymphatics (double
arrows). |
 |
Slide 4
Is a section taken
through the full thickness of the esophageal wall. Carcinomas of the
esophagus are typically deeply infiltrating lesions and this one has
extended through the muscularis propria (arrows). |
