Prepubertal hypertrichosis is characterized by an excess of hair growth, seen during birth and progressing during childhood. [3] [6] In generalized hypertrichosis, excessive hair growth occurs all over the body, whereas in localized hypertrichosis, excessive hair growth only occurs in certain areas of the body. [2]
Each involves the external ear. The difference between them is that a cyst does not connect with the skin, but a sinus does. [ 3 ] Frequency of preauricular sinus differs depending the population: 0.1–0.9% in the US, 0.9% in the UK, and 4–10% in Asia and parts of Africa.
