Abstract:
A 67-year-old male developed primary gastric squamous cell carcinoma (SCC) 13 years after undergoing distal gastrectomy for gastric cancer. Gastroscopy revealed a type 2 gastric remnant tumor and tumor biopsies revealed poorly differentiated carcinoma. The patient underwent remnant gastrectomy with lateral segment hepatectomy, splenectomy, partial resection of diaphragm, and distal partial esophagectomy. The histological findings revealed SCC without an adenocarcinoma component in the gastric remnant tumor. The patient died 13 months after surgery due to multiple-organ metastasis of gastric SCC. The post-operative prognosis of gastric SCC cases tends to poorer than that of gastric adenocarcinoma. Early diagnosis is important to improve the prognosis of primary gastric SCC and pathogenetic analysis of gastric SCC may contribute to improving the diagnosis and treatment of carcinogenesis and the prognosis of gastric SCC.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
