Hilton's white line is a boundary in the anal canal.^[1]

Below it, lymphatic drainage is to the superficial inguinal nodes.^[2]

Hilton's white line is slightly below the pectinate line, a landmark for the intermuscular border between internal and external anal sphincter muscles.

This line represents the transition point from non-keratinized stratified squamous epithelium of the anal canal to keratinized stratified squamous epithelium of the anus & perianal skin.^[3]

In live persons the color of the line is white, hence the name.

It is named for John Hilton.^[4]
