Abstract PDF PubReader ePub

Schwannomas are uncommon neoplasms that arise from Schwann cells of the neural sheath. Gastrointestinal schwannomas are rare among mesenchymal tumors of the gastrointestinal tract, and only a few cases have been reported to date. Duodenal schwannomas are usually discovered incidentally and achieving a preoperative diagnosis is difficult. Schwannomas can be distinguished from other subepithelial tumors on endoscopic ultrasonography; however, any typical endosonographic features of duodenal schwannomas have not been reported due to the rarity of these tumors. Immunohistochemistry is essential to distinguish schwannomas from gastrointestinal stromal tumors and leiomyomas. We report a case of duodenal schwannoma found incidentally during a health check-up endoscopy. On endoscopic ultrasonography, this tumor was suspected as a gastrointestinal stromal tumor; therefore, the patient underwent laparoscopic wedge resection of the tumor. Histopathology and immunohistochemistry confirmed that the duodenal lesion was a benign schwannoma.

Magnifying Endoscopy for Esophageal Ectopic Sebaceous Glands: Mu Song Jeon, Gwang Ha Kim, Dong Young Jeong, Byeong Kyu Park, Moon Won Lee, So-Jeong Lee, Do Youn Park; Clin Endosc 2018;51(5):495-497. Published online February 26, 2018; DOI: https://doi.org/10.5946/ce.2017.187

Abstract PDF PubReader ePub

Ectopic sebaceous glands are found very rarely in the esophagus; heretofore, several cases have been reported. The sebaceous gland is originally a source of an endodermal origin; however, there have been controversies regarding whether the origin of the esophageal ectopic sebaceous gland is ectodermal or endodermal. Ectopic sebaceous glands of the esophagus usually do not cause symptoms; thus, they are often found incidentally on endoscopy for routine health screening. Endoscopic findings are characterized by single or multiple yellow patches or nodular lesions of various sizes, sometimes with small central openings. We report two cases of esophageal ectopic sebaceous glands found incidentally during endoscopy with magnifying endoscopic findings. The lesions were in the mid-esophagus and lower esophagus, respectively, and both endoscopic findings were similar as multiple yellowish patches or plaques. Magnifying endoscopy revealed the openings of the excretory ducts surrounded by circular microvessels in both cases.

A Rare Case of Early Gastric Cancer Combined with Underlying Heterotopic Pancreas: Jung Bin Yoon, Bong Eun Lee, Dae Hwan Kim, Do Youn Park, Hye Kyung Jeon, Dong Hoon Baek, Gwang Ha Kim, Geun Am Song; Clin Endosc 2018;51(2):192-195.

Abstract PDF PubReader ePub

Heterotopic pancreas in the stomach is usually asymptomatic and benign. Here, we presented a rare case of an early gastric cancer overlying a heterotopic pancreas. A 48-year-old woman underwent esophagogastroduodenoscopy, which revealed a subepithelial mass measuring 2.0×1.5 cm on the gastric antrum with a 1-cm erosive erythematous discoloration on the surface. A biopsy specimen showed moderately differentiated tubular adenocarcinoma. Endosonography showed a heterogeneous hypoechoic mass measuring 1.3×0.6 cm, with indistinct margins in the second and third layers of the gastric wall; anechoic tubular structures within the mass were suggestive of heterotopic pancreas. Distal gastrectomy was performed, which confirmed an early gastric cancer confined to the mucosa, and a separate underlying heterotopic pancreas. Although heterotopic pancreas is most likely benign, careful endoscopic observation of the mucosal surface is necessary to avoid overlooking a coincident early gastric cancer.

Background
/Aims: Gastric schwannomas are rare benign mesenchymal tumors that are difficult to differentiate from other mesenchymal tumors with malignant potential, such as gastrointestinal stromal tumors. This study aimed to evaluate the characteristic findings of gastric schwannomas via endoscopic ultrasonography (EUS).
Methods
We retrospectively reviewed the EUS findings of 27 gastric schwannoma cases that underwent surgical excision at Pusan National University Hospital during 2007 to 2014.
Results
Gastric schwannomas were mainly located in the middle third of the stomach with a mean tumor size of 32 mm. All lesions exhibited hypoechoic echogenicity, and 24 lesions (88.9%) exhibited heterogeneous echogenicity. Seventeen lesions (63.0%) exhibited decreased echogenicity compared to the normal proper muscle layer. Distinct borders were observed in 24 lesions (88.9%), lobulated margins were observed in six lesions (22.2%), and marginal haloes were observed in 24 lesions (88.9%). Hyperechogenic spots were observed in 21 lesions (77.8%), calcifications were observed in one lesion (3.7%), and cystic changes were observed in two lesions (7.4%).
Conclusions
During EUS, gastric schwannomas appear as heterogeneously hypoechoic lesions with decreased echogenicity compared to the normal proper muscle layer. These features may be helpful for differentiating gastric schwannomas from other mesenchymal tumors.

Acute Ectopic Pancreatitis Occurring after Endoscopic Biopsy in a Gastric Ectopic Pancreas: Seong Jun Lee, Gwang Ha Kim, Do Youn Park, Sang A Choi, Sang Hee Lee, Yu Yi Choi, Moo Song Jeon, Geun Am Song; Clin Endosc 2014;47(5):455-459. Published online September 30, 2014; DOI: https://doi.org/10.5946/ce.2014.47.5.455

Abstract PDF PubReader ePub

Ectopic pancreas is a congenital anomaly and the most common type of ectopic tissue in the gastrointestinal tract. Most patients with an ectopic pancreas are asymptomatic and rarely have complications. Ectopic pancreatitis after an endoscopic biopsy has not been reported. We report a patient who developed acute ectopic pancreatitis in the stomach after an endoscopic biopsy. A 71-year-old male patient presented with a subepithelial tumor (SET) in the stomach and had no symptoms. Endoscopic ultrasonography demonstrated a 30-mm hypoechoic mural mass, lobulated margins, and anechoic duct-like lesions. To obtain proper tissue specimen, endoscopic biopsy was performed through the opening on the surface of the mass. The pathologic results confirmed an ectopic pancreas. One day after the endoscopic biopsy, he developed persistent epigastric pain. His serum amylase and lipase elevated. Computed tomography of the abdomen showed swelling of the SET and diffuse edema of the gastric wall. His condition was diagnosed as acute ectopic pancreatitis occurring after endoscopic biopsy.

A Case of Squamous Metaplasia of the Stomach: Moo Song Jeon, Gwang Ha Kim, Do Youn Park, Jae Hoon Jeong, Dong Hwahn Kahng, Hye Yoon Jang, Jong Hyun Choi, Eun Kyoung Park; Clin Endosc 2013;46(4):407-409. Published online July 31, 2013; DOI: https://doi.org/10.5946/ce.2013.46.4.407

Abstract PDF PubReader ePub

Intestinal metaplasia of the stomach is a common metaplastic lesion associated with chronic gastritis and mucosal atrophy. However, squamous metaplasia is a comparatively rare condition. On endoscopy, squamous metaplasia is usually observed as a whitish mucosal lesion in the lesser curvature of the cardiac region of the stomach. When Lugol's iodine solution is applied, the lesion stains brown in the same way as normal esophageal mucosa. We report a case of 79-year-old man with a whitish flat lesion in the lesser curvature of the cardiac region on surveillance endoscopy after endoscopic treatment of gastric adenoma. The endoscopic biopsy showed stratified squamous epithelial mucosa.

A Submucosal Tumor-Like Recurrence of Early Esophageal Cancer after Endoscopic Submucosal Dissection: Jeong Cheon Choi, Gwang Ha Kim, Do Youn Park, Hyeog Gyu Seoung, Yong Jae Lee, Ji Hye Kim, Tae Kyun Kim, Hoseok I; Clin Endosc 2013;46(2):182-185. Published online March 31, 2013; DOI: https://doi.org/10.5946/ce.2013.46.2.182

Abstract PDF PubReader ePub

Early esophageal cancer is defined as a tumor invading the mucosa with or without lymph node or distant organ metastasis. In the current guidelines for early esophageal cancer, absolute indication for endoscopic resection include lesions limited to the epithelium or lamina propria mucosa not exceeding two-thirds of the circumference, and relative indications include lesions limited to the muscularis mucosa or the upper third of the submucosal layer and not accompanied by clinical evidence of lymph node metastasis. After endoscopic submucosal dissection for early esophageal cancer, locally recurrent cancer can occur, especially in the case of incomplete resection. Here, we report a rare case of a submucosal tumor-like recurrence after endoscopic resection of early esophageal cancer.
