Pathologic Features of Esophageal and Gastric Malignancies.

Esophageal and gastric carcinomas affect millions of individuals worldwide, placing a considerable burden on society. Unfortunately, preventative medicine falls short as screening methods for the upper gastrointestinal tract lack the ability to detect early onset disease. The overwhelming majority of cases present after symptoms appear when individuals have advanced disease with a poor prognosis. Further complicating matters, the anatomic location of these neoplasms engenders rapid tumor progression, which repeatedly thwarts successful surgical treatment. This chapter will focus on the pathological features of malignant neoplasms of the esophagus and stomach.
