A Case of Gastric Granular Cell Tumor: Review of Literature and Features of Endoscopic Ultrasonography

Granular cell tumor was originally described as granular cell myoblastoma by Abrikossoff. The incidence of GCT in the gastrointestinal tract is low, and most granular cell tumors occur in the esophagus and large bowel. Gastric granular cell tumors are rare and difficult to distinguish from carcinoid tumors by gross endoscopic findings and endoscopic ultrasonography findings. We report a case of gastric granular cell tumor, treated by endoscopic submucosal dissection, and review the endoscopic ultrasonography findings of recently reported gastric granular cell tumors.

Variant Angina Associated with Migrating Spontaneous Occlulsive Vasospasm of Right Coronary Artery / 고신대학교의과대학학술지

Variant angina is a syndrome of cyclical chest pain at rest caused by vasospasm and associated with ST-segment elevation. Most of these cases are induced by the provocation with ergonovine or acetylcholine, and mechanical irritation of coronary artery by catheter, but spontaneous migrating spasm in right coronary artery is very rare. We report a fifty one year old male patient presenting as a variant angina due to spontaneous migrating spasm in right coronary artery during diagnostic coronary angiogram. The spasm was relieved spontaneously or by the administration of intracoronary nitroglycerin. No chest pain was documented after medication with calcium-channel blocker and nitrates on 6 month clinical follow-up. This paper presents our experience with a patient presenting with migrating coronay vasospasm of right coronary artery.
