A severe cryptitis may lead to a crypt abscess. Pathologic processes that lead to Crohn's disease, i.e. progressive intestinal crypt destruction, are associated with branching of the crypts. Causes of crypt branching include:
WebIn between the villi are crypts (Crypts of Lieberkuhn) that invaginate down into the mucosa. The villi should be approximately 3 times the height of the crypts. The epithelium is intestinal type, which means goblet cells are interspersed among the tall columnar absorptive cells known as enterocytes. WebSubjective methods to grade celiac disease histological severity include the Marsh-Oberhuber and Corazza-Villanacci systems. Quantitative histology uses villus height (Vh), crypt depth (Cd), and intra-epithelial lymphocyte count (per 100 enterocytes) to provide objective measures of histologic changes including Vh:Cd ratio.
