* The primary insult is to crypt cells.

** Crypt cell death leads to dilated gland lumens (cysts).
 
** Production is impaired, eventually leading to insufficient cells for villi. 
 
* Enterocytes lost to lumen are replaced by increasingly immature cells.
 
** Gives rise to severe malabsorption.
 
* If damage is severe, erosions/ulcers may form which may eventually heal.
 
** Even if there are no ulcers, damage can be long-term
 
*** Causes long-term malabsorption.
 
* Examples include:
 
** '''Parvovirus'''
 
*** Target crypt cells.
 
** '''Lymphoma'''
 
*** Numerous neoplastic lymphocytes compress crypts.
 
** '''Cytotoxic chemicals'''
 
*** Dividing crypt cells are susceptible.

Villus Atrophy

  • Commonly seen in enteric disease.
  • Occurs when more enterocytes are lost than are produced in the crypts.
  • Causes malabsorption of nutrients and water.
  • There are two main types of villus atrophy:

Villus atrophy with intact/hypertrophic crypt glands

Villus atrophy with damage to crypts

Enteritis Particularly Associated with Villus Atrophy

Rotavirus

Cryptosporidium
