    Notes: Abstract Two patients with carcinoma of the cystic duct presented with obstructive jaundice due to extrinsic compression of the common hepatic duct by the tumor. Sonography and computed tomography showed dilatation of the intrahepatic bile ducts and gallbladder. In one patient, a calculus seen in the gallbladder neck suggested Mirizzi syndrome. In the other, a small soft tissue mass was indistinguishable from a common duct tumor or an enlarged lymph node. In both cases, direct cholangiography demonstrated extrinsic compression and displacement of the common duct with proximal biliary dilatation and nonvisualization of the gallbladder. Carcinoma of the cystic duct should be considered whenever there is evidence of cystic duct obstruction and/or when cholangiography shows extrinsic mass effect on the common duct.

    Notes: Abstract A traumatic neuroma of the intestine arising at the site of a previous ileocolic anastomosis is reported. Barium enema examination showed an extramucosal mass in a patient who presented with abdominal pain, rectal bleeding, and anemia. Although rare, traumatic neuroma should be included in the differential diagnosis of an intestinal mass occurring after intestinal surgery.

    Notes: Summary A 52-year-old woman initially presented to our medical center with synchronous, submucosal tumors of the esophagus, stomach, and transverse colon. The gastric and colonic tumors were resected, and both displayed infiltrating sheets of polygonal cells with coarsely granular cytoplasm and small vesicular nuclei. The neoplastic cells of both tumors were immunoreactive for S-100 protein. Ultrastructural studies revealed the lysosomal nature of the cytoplasmic granules. Although the esophageal mass was not resected, it was felt that this represented another focus of granular cell tumor of the gastrointestinal tract. Two years later, she presented with disseminated squamous carcinoma of the esophagus. At autopsy, a submucosal granular cell tumor was found adjacent to the squamous carcinoma of the esophagus. To our knowledge, this is the first reported case of synchronous granular cell tumors that involved multiple segments of the gastrointestinal tract, one of which was later associated with a squamous carcinoma of the esophagus.

    Notes: Abstract To determine the incidence and significance of Campylobacter pyloriin patients undergoing routine endoscopic evaluation at this hospital, biopsies of the antrum were obtained from 132 patients and from 15 asymptomatic volunteers. Specimens were cultured and silver stained for the presence of C. pyloriand were examined histologically. C. pyloriwas detected in 67 (51%) patients and two (13%) volunteers (P=0.006).In patients, C. pyloriwas found significantly more often when the mucosa was inflamed (67%) than when the mucosa was normal (13%), and both volunteers with C. pylorihad chronic gastritis on histological examination. When compared to the volunteers, patients with upper gastrointestinal symptoms had a significantly increased prevalence of antral inflammation, even if the endoscopic examination was normal. C. pyloriis infrequently found in young asymptomatic adults but is found in both asymptomatic volunteers and patients in association with all forms of histological antral gastritis which is prevalent in patients with both normal endoscopic findings and peptic ulcer disease.
