The anocutaneous line, also called the Hilton white line or intersphincteric groove, is a boundary in the anal canal.[1]
Below the anocutaneous line, lymphatic drainage is to the
superficial inguinal nodes.[2]
The anocutaneous line is slightly below the pectinate line and a landmark for the intermuscular border between internal and external anal sphincter muscles.
The anocutaneous line represents the transition point from non-keratinized
perianal skin.[3]
In live persons, the color of the line is white, hence the alternative name. It is named for John Hilton.[4]
