Eosinophilic Gastroenteritis Masquerading as Ampullary Adenoma

Abstract: Eosinophilic gastroenteritis is a rare gastrointestinal disorder of undetermined etiology that is characterized by eosinophilic infiltration of the gut wall. The presenting symptoms depend on the site and depth of intestinal involvement and varies from nausea, vomiting, and abdominal pain to acute bowel obstruction. Pancreaticobiliary obstruction caused by eosinophilic gastroenteritis is rare. We report a 39-year-old man who presented with abdominal pain, vomiting, abnormal liver tests, and a duodenal mass on … Show more

“…Involvement of the serosal layer may cause peritoneal irritation, which can lead to ascites, peritonitis and perforation in more severe cases; intestinal intussusception may occur in the serosal type as well[17]. An additional manifestation of the disease, peripapillary duodenal disease, which is secondary to the eosinophilic infiltration of the peripapillary duodenal region, might result in pancreatitis and biliary obstruction[18,19]. …”

“…EG may present as gross appearance of a malignant gastric ulcer, however presentation as gastric or duodenal ulcer is extremely rare. As EG lacks specific symptoms and may mimic malignancy (even surgery had been reported in EG patient for suspicion of malignancy),[ 2 3 4 ] it should be considered in the differential diagnosis of atypical cases as the present case which had a nonhealing gastric ulcer with the appearance of a malignant lesion, however, without constitutional symptoms of gastric malignancy. EUS in cases of EG may show thickening of mucosa and submucosa or normal wall layer pattern in cases of mucosal form of the disease.…”

“…EG can be divided into mucosal form (may present as pain, nausea, vomiting, diarrhea, fecal occult blood loss, anemia, or protein-losing enteropathy), muscular form (present as intestinal obstruction) and serosal form (present as ascites). [ 1 2 ] The presenting symptoms depend on the site and depth of intestinal involvement. In the present case, both CT and EUS suggested malignancy.…”

“…Peripheral eosinophilia and elevated IgE are suggestive findings of initial laboratory testing. 3,15 Additional testing may include allergy evaluation by skin and serum radioallergosorbent tests, albumin and protein levels, ␣-1 antitrypsin levels, and analysis of ascitic fluid for eosinophils. 1 Radiologic tests are nonspecific but may show varying degrees of inflammation such as mucosal thickening and irregularity.…”
