The Sydney System for the classification of gastritis emphasized the importance of combining topographical, morphological, and etiological information into a schema that would help to generate reproducible and clinically useful diagnoses. To reappraise the Sydney System 4 years after its introduction, a group of gastrointestinal pathologists from various(More)
The term inflammatory bowel disease (IBD) is viewed as all-inclusive, covering the full panoply of intestinal disorders in which inflammatory changes are a prominent feature, including those of infectious, toxic, and intrinsic origin as well as the idiopathic entities ulcerative colitis and Crohn's disease. This chapter describes and discusses those aspects(More)
We examined 134 members of 16 families with Gardner's syndrome for pigmented ocular fundus lesions. Of 41 patients with documented Gardner's syndrome, 37 (90.2 percent) had such lesions. The lesions were bilateral in 32 of the patients (78.1 percent) and in 2 of 42 controls (4.8 percent). Twenty (46.5 percent) of 43 first-degree relatives at 50 percent risk(More)
The Peutz-Jeghers syndrome is an autosomal dominant hereditary disease characterized by hamartomatous polyps of the gastrointestinal tract and by mucocutaneous melanin deposits. The frequency of cancer in this syndrome has not been studied extensively. Therefore, we investigated 31 patients with the Peutz-Jeghers syndrome who were followed from 1973 to(More)
Severe gastrointestinal necrosis and strictures after an iron overdose are well described. However, mucosal injury in patients receiving therapeutic iron has received only scant recognition despite its wide use. We studied the clinical and histologic features of 36 upper gastrointestinal tract biopsies from 33 patients (24 gastric, 9 esophageal, 1(More)
Lymphocytic colitis, previously termed "microscopic colitis", is a clinicopathologic syndrome of watery diarrhea, grossly normal colonoscopy, and mucosal inflammatory changes. Since lymphocytic colitis is a new, incompletely characterized entity, a histopathologic study was performed to compare lymphocytic colitis (n = 16), collagenous colitis (n = 17),(More)
Collagenous colitis is a clinicopathologic syndrome with chronic watery diarrhea, diffuse colitis with surface epithelial injury, and a distinctive collagen band beneath the surface epithelium especially in the proximal colon. The cases of seven patients (including six middle-aged women) with chronic, watery, noninfectious diarrhea were studied.(More)
The histopathologic features of collagenous colitis were studied in 14 women and one man. All but one patient presented with chronic watery diarrhea: 10 had a history of thyroid disease or unspecified arthritis. All 15 patients showed characteristic thickening of the subepithelial collagen layer (SCL) in colorectal biopsy specimens, but in the distal(More)
The surgically created squamocolumnar junction in patients who have undergone an esophagogastrostomy after partial esophagogastrectomy provides a unique opportunity to study mucosal regeneration in the setting of gastroesophageal reflux. The pathological and clinical findings in 17 such patients are presented. In each patient the anastomosis had been(More)
