Core Tip
Core Tip: Submucosal hematoma of the stomach or esophagus is rare and can result due to endoscopic therapy, coagulopathy, trauma, anticoagulation therapy, or repeated vomiting. The presence of both esophageal and gastric submucosal hematomas is rare. We present a 57-year-old male with huge gastric and esophageal submucosal hematomas. Endoscopy showed esophageal stenosis; computed tomography confirmed the diagnosis of gastric and esophageal submucosal hematomas associated with arterial malformations. The patient has a history of hypertension. The appearance of vascular malformations in the patient may be due to long-term hypertension causing endothelial damage in the blood vessels. Vascular embolization of the malformed arteries was performed first, followed by conservative treatment of the hematomas. The patient’s symptoms were relieved, and the hematomas were reduced.
