What does cribriform mean?

Pathologists use the word cribriform to describe cells that are growing and connecting together in a way that creates a pattern of small holes in between the cells. This pattern of growth can only be seen after the tissue sample is examined under the microscope.

Cribriform is an abnormal pattern of growth that can be seen in many different types of tumours. For this reason, this pattern of growth is not a diagnosis and pathologists use it along with other information about the tumour to make a diagnosis.

Examples of tumours that can show a cribriform pattern of growth:
