摘要:

Obstruction of the stomach or of the duodenum as a result of inflammatory pancreatic disease occurs in approximately 1 % of patients who develop pancreatitis. Duodenal compression is usually the cause of anatomic obstruction. We present a patient who developed anatomic gastric outlet obstruction, reflux esophagitis, and a severe motor disorder of the esophagus due to an annular pancreatic pseudocyst that totally surrounded the distal antrum. After draining the pseudocyst, the symptoms of gastric outlet obstruction and reflux esophagitis resolved, but the esophageal motor disorder persisted. Pseudocyst formation can present in unusual ways and must be considered in the differential diagnosis of gastric outlet obstruction and esophageal reflux. Persistence of the esophageal motor disorder suggests that peristalsis of the distal esophagus is a myogenic function.

摘要:

A patient with a carcinoid of the ampulla of Vater presented with jaundice, generalized pruritus and a palpable gallbladder. Percutaneous intrahepatic cholangiogram showed a small mass of the ampulla of Vater with intraluminal protrusion of the common bile duct. A pancreatico-duodenectomy was performed. Microscopically, the lesion was composed of solid nests of large cells with foamy cytoplasm which did not stain for mucin and were argyrophil and argentaffin negative. Ultrastructurally, tumor cells contained dense-core granules and whorls of microfilaments. Immunoperoxidase staining demonstrated neuron-specific enolase in tumor cells; however, there was no staining for immunoactive adrenocorticotropic hormone, bombesin, gastrin, somatostatin, calcitonin, glucagon, insulin, parathormone or carcinoembryonic antigen. There was no evidence of metastases to regional lymph nodes and the patient has no evidence of recurrence 18 months later.

摘要:

Fibrous histiocytomas are mesenchymal neoplasms that uncommonly involve visceral organs. Two patients are reported in whom fibrous histiocytoma arose in the colonic wall and the head of the pancreas, mimicking carcinoma of those sites at the initial presentation. Pathological features and therapy of these tumors are discussed.
