| [ Summary ] | Colorectal carcinomas (CRCs) in patients with Lynch syndrome are characterized by medullary growth, poorly differentiated histology, mucinous or signet ring differentiation, tumor infiltrating lymphocytes and Crohn's-like lymphocytic reactions. These features are also commonly accepted as being CRC associated with a high probability of microsatellite instability. Lynch syndrome is therefore defined as a patient harbored pathogenic germline mutation in one of the DNA mismatch repair genes. Recognition of these histological features may contribute to the detection of CRC derived from this significant hereditary disease in routine pathological practice. | |
