Anocutaneous line

Anocutaneous line is a term used in anatomy to describe the line that separates the anus from the perineum. This line is also known as the Hilton's white line, named after the British surgeon John Hilton.

Etymology

The term "anocutaneous line" is derived from the Latin words "anus", which means ring or circle, and "cutaneous", which refers to the skin. The term "Hilton's white line" is named after John Hilton, a British surgeon who first described this anatomical feature.

Anatomy

The anocutaneous line is a visible line that separates the anus from the perineum. It is formed by the junction of the skin and the mucous membrane of the anus. This line is important in surgical procedures involving the anus and perineum, as it marks the boundary between the internal and external parts of the anus.

Clinical significance

The anocutaneous line is an important landmark in surgical procedures involving the anus and perineum. It helps surgeons to identify the boundary between the internal and external parts of the anus, which is crucial in procedures such as hemorrhoidectomy and anal fissure repair.
