Typically, patients are asymptomatic and usually only present symptoms (pain, erythema, discharge from pit) in relation to infection. Renal and inner ear anomalies may be associated.

Preauricular sinus and cyst
Preauricular sinuses, also known as preauricular pits and preauricular cysts, are common malformations present at birth that involve the external ear. A cyst does not connect with the skin, while a sinus does. Both ears are often affected. They may be associated with other defects such as branchio-oto-renal syndrome. They are often inherited from a persons parents. They affect about 0.1–0.9% of people in the US, 0.9% in the UK, and 4–10% in Asia and parts of Africa.
