Choledochal cyst is an uncommon premalignant anomaly. The morphology and pathogenesis of the premalignant lesion of cholangiocarcinoma arising from the choledochal cyst has not been well described. Herein, we report a rare case of bile duct adenoma arising from choledochal cyst with anomalous union of pancreaticobiliary duct (AUPBD). 50-year-old woman was admitted to our hospital with the complaint of epigastric pain. She had received common bile duct (CBD) exploration and choledocholithotomy and cholecystectomy 3 months earlier under the diagnosis of multiple CBD stones. Intraoperalive cholangiogram was not remarkable except CBD dilatation at that time. Endoscopic retrograde cholangiopancreatography revealed choledochal cyst with AUPBD and round filling defect which disappeared easily on the balloon cholaniogram. On magnetic resonance cholangiopancreatography, the filling defect was confirmed as 2 cm polypoid mass attached to the distal bile duct wall. At laparotomy, a soft whitish mass was palpable on the lower CBD. On histological examination, adenoma with focal carcinoma change arising from choledochal cyst was diagnosed.

Epiploic appendagitis is a relatively rare cause of acute abdominal pain. Usually, epiploic appendagitis is a benign and self-limited condition, but it can be clinically misdiagnosed as acute appendicitis or diverticulitis, so an inaccurate diagnosis may lead to unnecessary treatment. We recently managed 7 cases of epiploic appendagitis during 1 year and review these cases with an emphasis on the clinical diagnostic features. The main pathophysiologic mechanism underlying epiploic appendagitis is thought to be triggered by appendageal torsion and caused by a subsequent blood flow disturbance. This medical condition must be kept in mind when a patient with acute abdominal pain has well-localized pain which is characteristically sharp in nature and a mild systemic inflammatory response compared to the severity of the pain.

Overlap of autoimmune hepatitis and systemic lupus erythematosus (SLE) is a comparatively rare condition. Although both autoimmune hepatitis and SLE can share common autoimmune features such as polyarthralgia, hypergammaglobulinemia and positive ANA, it has been considered as two different entities. We report a case of anti- LKM1 positive autoimmune hepatitis who developed SLE two years later. The presence of interface hepatitis with lymphoplasma cell infiltrates and rosette formation points to the autoimmune hepatitis rather than SLE hepatitis. Autoimmune hepatitis is infrequently accompanied by SLE, therefore, it could be recommended to investigate for SLE in patients with autoimmune hepatitis. (Korean J Gastroenterol 2008;51:190-193)

Pneumatosis cystoides intestinalis (PCI) is an uncommon disease that involves submucosa or subserosa layer of gastrointestinal tract. We report a case of PCI in a 71-year-old man. The patient initially complained of weight loss for 3 months. Patient had no specific previous medical history. Simple abdominal X-ray demonstrated numerous small air densities on right lower abdomen. Colonoscopy revealed numerous sessile polypoid, balloon-like distended, protruding subepithelial mass covered with normal colonic mucosa from proximal ascending colon to hepatic flexure. Abdominal CT scan showed numerous intraluminal gas collection. Etiology and pathogenesis of PCI remain uncertain. PCI is often associated with various pulmonary disease, connective tissue disease, and endoscopic procedures. We reviewed literatures for possible cause of PCI in this case.
