Cribriform

Cribriform is a term used in anatomy and pathology to describe a sieve-like structure or pattern. The term is derived from the Latin word "cribrum" which means sieve and the suffix "-form" which means shape or resemblance. The term is often used to describe the appearance of certain tissues under a microscope, particularly in the context of cancer diagnosis.

Anatomy

In anatomy, the term cribriform is often used to describe the cribriform plate of the ethmoid bone in the skull. This thin, delicate structure separates the nasal cavity from the brain and is perforated with many tiny holes, or foramina, through which the olfactory nerves pass.

Pathology

In pathology, a cribriform pattern is often seen in certain types of cancer, including adenoid cystic carcinoma and some forms of prostate cancer. In these cases, the cancer cells form clusters with multiple small spaces, resembling a sieve. This pattern can be an important diagnostic feature.
