A Case of Invasion of Muscularis Propria of Gastric Inflammatory Fibroid Polyp
이지현,유진세,정호연,김희만,류훈,조미연,김현수 대한상부위장관ㆍ헬리코박터학회 2015 Korean Journal of Helicobacter Upper Gastrointesti Vol.15 No.4
Inflammatory fibroid polyp (IFP) is an uncommon benign tumor and a proliferative disease localized to the submucosal area of the gastrointestinal tract. IFP has been detected more frequently with the increasing use of endoscopy. Histologically, gastric IFP is mostly limited to the submucosa, rarely invading the muscle layer. However, we experienced a case of gastric IFP invading the proper muscle layer. A 62-year-old man was referred for evaluation of epigastric pain. Contrast enhanced computed tomography of the abdomen and endoscopic examination revealed a stomach mass. IFP was histologically confirmed by surgical resection, and the patient was discharged without complication. IFP originating in the stomach that invades the muscularis propria is rare compared to that originating in the large or small intestine. The incidence of gastric IFP is relatively low. Invasion of the muscularis propria by IFP depends not only on the location but also the size of the IFP. There have been no published reports on the outcomes of gastric IFP invading the muscularis propria, therefore close follow-up of the present patient is important.

A Case of Dermatomyositis in a Patient with a Neuroendocrine Tumor at the Ampulla of Vater
박정은,강태영,유진세,이향선 대한내과학회 2017 대한내과학회지 Vol.92 No.6
Dermatomyositis is an autoimmune disease characterized by chronic muscle inflammation that results in specific dermatological signs and decreased muscle strength. It is known to have a strong association with malignancy. Most neuroendocrine tumors arise from the gastrointestinal tract, with less than 1% of cases occurring at the ampulla of Vater. While cases of dermatomyositis associated with neuroendocrine tumors have been reported internationally, to date there have been no cases reported in Korea. This case report presents a 33-year-old male who had undergone pylorus-preserving pancreaticoduodenectomy for a neuroendocrine tumor located at the ampulla of Vater, and had been followed at the hospital after his procedure. Three years post-surgery, the patient developed serious muscle weakness in his upper-right and lower-left extremities, and was subsequently diagnosed with dermatomyositis. This paper presents the first domestic case of dermatomyositis developing in the context of a neuroendocrine tumor at the ampulla of Vater. A literature review on this subject follows in the discussion.
