Identification and classification of dysplasia in patients with ulcerative colitis or Crohn's disease in the large intestine is a challenge. Surveillance programs in these patients aim to detect colitis-associated dysplasia at an early stage, as the risk of these patients developing colorectal cancer is considerable. Good communication and discussion between pathologists and endoscopists is essential to help reach unequivocal diagnoses and to improve the management of colitis-associated dysplasia.
