Gastric cancer, particularly adenocarcinoma, shows distinctive histological features. These include the presence of malignant cells forming irregular and disorganized glandular structures within the gastric mucosa. There may also be a desmoplastic reaction characterized by an increase in fibrous tissue, and the presence of signet ring cells is a hallmark of diffuse-type gastric adenocarcinoma. Early detection through histological examination is critical for the prognosis and treatment of gastric cancer.
