What is the cribriform pattern?

The cribriform pattern refers to a histological appearance characterized by small, sieve-like spaces or holes within a tissue, often seen in certain types of tumors, particularly in prostate cancer and some types of Breast cancer. This pattern typically indicates a specific arrangement of cells and can be associated with more aggressive tumor behavior. The term "cribriform" is derived from the Latin Word for "sieve," reflecting the perforated look of the tissue architecture. Pathologists use this pattern as part of their diagnostic criteria to assess tumor characteristics and guide treatment decisions.
