A simian crease, one type of palmar crease.

A palmar crease is a type of crease on the palm. A single transverse palmar crease also called simian crease is sometimes associated with Down syndrome.[1] Other types of creases include the Sydney crease and the Suwon, or double transverse palmar crease.[2]

Analysis of palmar creases is not very objective on the contrary to fingerprint analysis.[3] Palmar creases are sometimes used as a preoperative landmark for identification of deep anatomical structures. This method was shown to be unuseful.[4]
