Enteritis cystica profunda with lipoma in the second portion of the duodenum: a case report.

Enteritis cystica profunda (ECP), a rare and benign condition, is defined as the displacement of the glandular epithelium into the submucosa and more profound layers of the small intestinal wall leading to the formation of mucin-filled cystic spaces. ECP frequently occurs in the ileum or jejunum and is associated with diseases such as Crohn disease and Peutz-Jeghers syndrome. ECP also develops in the absence of known pathology.

[Anisakiasis Induced Segmental Jejunum Obstruction].

Human anisakiasis is a disease caused by an infestation of the third stage larvae of family anisakidae. The ingested larvae invade the gastrointestinal wall, causing clinical symptoms that include abdomen pain, nausea, and vomiting. Although enteric anisakiasis is extremely rare, it can induce intestinal obstruction.

Predictive Factors for Severe Outcomes in Ischemic Colitis.

Background/aims: Ischemic colitis includes a wide clinical spectrum ranging from mild to severe forms. This study aimed to determine the factors that are related to the occurrence of severe ischemic colitis.

Methods: This multicenter study was conducted retrospectively in Korea.

Adenosquamous carcinoma of the ascending colon: a case report and review of the literature.

An adenosquamous carcinoma is a malignancy that has both glandular and squamous histologic components. Both components are malignant and have potential to metastasize. An adenosquamous carcinoma of the large bowel is rare, and its clinicopathologic behavior is not fully understood.

Efficacy of endoscopic submucosal resection with a ligation device for removing small rectal carcinoid tumor compared with endoscopic mucosal resection: analysis of 100 cases.

Aim:   Conventional endoscopic mucosal resection (EMR) of carcinoid tumors is often associated with involvement of the resection margin, which necessitates further intervention. Endoscopic submucosal resection with a ligation device (ESMR-L) is a novel technique for the removal of carcinoid tumors. The aim of the present study was to compare the clinical usefulness of endoscopic submucosal resection with a ligation device with that of EMR for the complete resection of rectal carcinoid tumors.

[A case of isolated hepatic lymphangioma].

Hepatic lymphangioma is a rare benign neoplasm. It usually occurs as a part of systemic lymphangiomatosis. Isolated hepatic lymphangioma is extremely rare.

Aberrant expression of MUC3 and MUC4 membrane-associated mucins and sialyl Le(x) antigen in pancreatic intraepithelial neoplasia.

Introduction: Ductal adenocarcinoma of the pancreas has recently been suggested to arise from histologically identifiable ductal lesions known as pancreatic intraepithelial neoplasia (PanINs). Altered levels and patterns of mucin gene expression have been reported to occur in epithelial cancers.

Aim: To examine the pattern of expression of membrane-associated mucins, MUC3 and MUC4, and a mucin-associated carbohydrate tumor antigen, sialyl Le(x), in these precursor lesions and ductal adenocarcinoma of the pancreas.

Aberrant expression of MUC5AC and MUC6 gastric mucins and sialyl Tn antigen in intraepithelial neoplasms of the pancreas.

Background & Aims: It has recently been suggested that infiltrating adenocarcinoma of the pancreas arises from histologically well-defined precursor ductal lesions called pancreatic intraepithelial neoplasia (PanIN-1A, -1B, -2, and -3). This study examined alterations in the pattern and the level of expression of several mucin genes (MUC1, MUC2, MUC5AC, and MUC6) and mucin-associated tumor antigens (Nd2 and sialyl Tn) in these precursor lesions.

Methods: We examined 139 PanINs and 68 infiltrating ductal adenocarcinomas of the pancreas by using immunohistochemistry and in situ hybridization methods.
