ARTICLE HIGHLIGHTS
Research background

Gastric glomus tumors are relatively rare, and there is little knowledge regarding their endoscopic ultrasound findings.

Research motivation

Knowledge of the endoscopic characteristics of gastric glomus tumor is helpful in the diagnosis and differential diagnosis, and avoiding unnecessary surgery.

Research objectives

To summarize the endoscopic ultrasound characteristics of gastric glomus tumors confirmed by histopathology, and to verify the effectiveness of these characteristics in clinical cases.

Research methods

The records of 12 consecutive patients undergoing endoscopic ultrasonography (EUS) examination, surgery and pathology analysis for gastric glomus tumors in one institution from 2013-2020 were reviewed. Analysis of the EUS characteristics of gastric glomus tumors (such as tumor location, shape, size, echogenicity, homogeneity, margins, layer of origin, and so on) was carried out.

Research results

Ten cases had smooth hemispherical bulges of the mucosa, the same color as the surrounding mucosa, and 2 cases had small concave ulcers on the mucosa surface, leading to hemorrhage. The lesions were located in the anterior wall of the gastric antrum in 3 cases and in the lesser curvature of the gastric antrum in 9 cases. EUS showed that the lesions were round, ranging in maximum diameter from 10 mm to 35 mm with a mean diameter of 20 mm. The echo was slightly hypoechoic, and uniform, accompanied by small hyperechoic spots in some. There were small anechoic areas in the larger lesions, and halos with a lower echo. The outer boundary of the halo was clear, and the inner boundary was fuzzy. All of the lesions originated from the muscularis propria.

Research conclusions

Typical manifestations of gastric glomus tumors include gastric antrum location, originate from the fourth layer, solitary, round and slightly hypoechoic lesions with halos at the margins.

Research perspectives

A multi-center study, with an expanded sample size and prospective verification is required.
