WebCrypt abscesses are the accumulation of inflammatory cells within the crypts of the gastrointestinal tract. There are two types of crypt abscesses: neutrophilic and apoptotic. The main causes of crypt abscesses, including infections and inflammatory bowel disease, involve acute inflammation. WebThe histologic features include increased numbers of intraepithelial lymphocytes, villous shortening or flattening, crypt hyperplasia, and infiltration of the lamina propria with lymphoid cells. These changes form a spectrum from mild to severe, and this spectrum can be quantified using a numerical grading scale called the Marsh criteria.
