Gastric Subepithelial Tumor Diagnosed by Transabdominal Ultrasonography

Splenic Cyst Mimicking Gastric Subepithelial Tumor Diagnosed by Endoscopic Ultrasonography

Recent research reveal that the diagnosis of gastric extraluminal compressions mimicking subepithelial tumor is increasing in numbers as esophagogastroduodenoscopy becomes widespread. Endoscopic ultrasonography is a very useful tool for differentiating extraluminal compressions from subepithelial tumors. Gastric extraluminal compressions are due to compression by either normal adjacent organs o...

Endoscopic Ultrasonography in the Diagnosis of Gastric Subepithelial Lesions

Subepithelial lesions occasionally found in the stomach of patients undergoing endoscopy may be either benign lesions or tumors with malignant potential. They may also appear due to extrinsic compression. Discrimination of gastric subepithelial lesions begins with meticulous endoscopic examination for size, shape, color, mobility, consistency, and appearance of the overlying mucosa. Accurate di...

Gastric Schwannoma Diagnosed by Endoscopic Ultrasonography-Guided Trucut Biopsy

Schwannomas of the gastrointestinal (GI) tract are rare subepithelial tumors comprising approximately 3.3% to 12.8% of all mesenchymal tumors of the GI tract. On endoscopic ultrasound (EUS) they are seen as hypoechoic tumors arising most commonly from the 4th proper muscle layer. Although EUS helps to distinguish tumor characteristics, tissue sampling is required for differentiation with other ...

Rare Subepithelial Mass Diagnosed as Gastric Splenosis via EUS-FNA

A 20-year-old woman was referred for evaluation of a gastric subepithelial mass, noted incidentally on an esophagogastroduodenoscopy performed for evaluation of dyspepsia (Figure 1). She had a past medical history of Diamond-Blackfan syndrome status post bone marrow transplant, and recurrent acute pancreatitis status post total pancreatectomy with splenectomy 4 years before presentation. Endosc...
