Pre-auricular pit

Pre-auricular pit

Description : Pre-auricular pits are shallow invaginations in the skin of the face which are located just in front of the anterior border of the anterior crus of the helix.

A cheesy discharge of desquamated keratin debris is sometimes encountered.

Pre-auricular pits are inherited by means of an autosomal dominant gene with incomplete penetrance and are most commonly seen in orientals, occurring in 10-14% of the population, and in blacks (5%).

They are most commonly unilateral (75%).
