Preauricular Sinus and Cyst
Preauricular sinus and cyst (pronunciation: pre-aw-rik-yuh-lar si-nus and sist) is a congenital malformation that presents as a small pit or dimple located near the external ear, specifically in the preauricular region.
Etymology
The term "preauricular" is derived from Latin, with "pre" meaning before and "auricular" referring to the ear. "Sinus" and "cyst" are both derived from Greek, with "sinus" meaning pocket or sac and "cyst" meaning bladder or sac.
Definition

Symptoms
Symptoms of a preauricular sinus or cyst include a small pit or dimple on the outside of the ear, infection which may result in redness, swelling and pain, and drainage of clear, yellow or bloody fluid.
