Endoscopic ultrasound (EUS) is is a technique used for the exploration of the digestive system, enabling the diagnosis and classification of gastric tumors. The aim of our study was to describe the contribution of EUS and fine needle aspiration in the diagnosis and determination of the histological type of gastric tumors. Our study consists of a retrospective descriptive study involving 36 patients. The mean age was 54 ± 14.4 years, with a female-to-male sex ratio of 2. EUS revealed an ulcerated and polypoid appearance with prominent folds in half of the cases. Fine needle aspiration biopsy was performed in 80.5% of cases. The histopathological findings were predominantly gastrointestinal stromal tumors and adenocarcinomas.
