The diagnoses which may be arrived at by examination of peroral small bowel mucosal biopsy specimens are presented. Celiac sprue, unclassified sprue (refractory sprue), infectious gastroenterititis, stasis syndrome and kwashiorkor have a severe mucosal lesion. Other clinical conditions are required to establish the diagnosis in these diseases. A number of diseases have specific diagnostic features. Included are Whipple's disease, abetalipoproteinemia, collagenous sprue, primary intestinal lymphoma, eosinophilic gastroenteritis, giardiasis, coccidiosis, strongyloidiasis, lymphangiectasis and the intestinal immunodeficiency diseases. Mucosal abnormalities may be present in other diseases but the diagnoses are usually made on other criteria than small bowel biopsy. These include vitamin B12 or folic acid deficiency, Crohn's disease, gastrinoma, acrodermatitis enteropathica, amyloidosis, chronic granulomatous disease, lipid storage diseases, histoplasmosis, capillariasis, cytomegalovirus infection, schistosomiasis and macroglobulinemia.

Involvement of the gastrointestinal tract in macroglobulinemia is exceedingly rare. We describe a patient with IgM biclonal immunoglobulin disorder associated with diffuse lymphoplasmacytic infiltration of the small intestine. This chronic illness was characterized by diarrhea, steatorrhea, and intestinal pseudo-obstruction. Full-thickness biopsy specimens of the jejunum showed stunted and fused villi, giardiasis, and a widespread cellular infiltrate in the lamina propria extending through the muscularis mucosae into the submucosa and muscular layers. The infiltrate had a cytologically benign appearance that was shown to be polyclonal by immunochemical stains. Intestinal vacuolated plasma cells were occasionally observed in electron microscopic study. The patient has not developed the features of Waldenstrom's disease on a clinical follow-up of 14 years.
