RESUMO
Gastric glomus tumors (GGTs) are rare mesenchymal neoplasms that arise from cells of the glomus body. These occur in the submucosa of the gastric wall and are usually benign in nature. However, it is difficult to predict tumor behavior due to the lack of reliable histological features. Diagnosis can be challenging due to the lack of specific clinical features, and radiologic and endoscopic findings. Computed tomography (CT) scan, esophagogastroduodenoscopy (EGD), and endoscopic ultrasound (EUS) are key diagnostic modalities. However, the final diagnosis depends on the postoperative immunohistochemical and pathological analysis. Most GGTs can be cured by surgical or endoscopic resection. We report a case of GGT in a middle-aged woman who presented with new-onset anemia and was found to have a gastric mass that was later diagnosed as GGT after immunohistochemical staining.
