NCIt definition : A rare disorder affecting the digestive tract. Its cause is unclear but may be attributed,
in part, to increased collagen synthesis without adequate fibrolysis. It is characterized
histologically by atrophy of mucosal villi and crypts with extensive subepithelial
collagen deposition. Clinical signs include nausea, vomiting, diarrhea and weight
loss. Unlike celiac sprue (celiac disease), a gluten-free diet does not predict a
certain regression of the disease. The clinical course follows a progression of malabsorption
leading to nutritional deficiencies, small bowel ulceration/perforation, lymphoma
and infection. Prognosis is usually dismal.;
