Abstract:
Objective:To investigate the clinicopathological characteristics of gastric adenocarcinoma of the fundic gland(GA-FG).Methods:A total of 6 patients with GA-FG admitted from January 2014 to May 2019 were identified at Shanghai Songjiang District Central Hospital.Analyzed endoscopic findings, pathological characteristics and immunohistochemical staining of the lesions and reviewed relevant literatures.Results:Among the 6 patients, 3 were male, 3 were female, and the mean age was 66 years. The most common clinical presentation was epigastric discomfort. Gastroscopic examination revealed an elevated or flat lesion in the body of the stomach, with a diameter of 0.4 to 1.0 cm. Histopathologically, they mainly composed of main cells, but there were also scattered parietal cells, arranged in an irregular tubular or cord-like structure, and formed anastomosis branches. The tumor cells were immunohistochemically positive for MUC6 and pepsinogen 1.Conclusions:GA-FG is a rare variant of well-differentiated adenocarcinoma. It is important to understand its clinical features and histological morphology for more accurate diagnosis.
