**"Is that a piercing?!"**
Very commonly I am asked "Hey! Do you have your ears pierced there?" Well the answer is "NO!" What my mistaken piercings are actually Preauricular glands! Preauricular glands are something you are either born with or your not. They're often mistaken as a piercing and usually come in one ear and not the other. However, I'm the lucky one that got not one but two of them.

It's not a freckle! I swear! Preauricular Sinus/glands are located near the front of the ear and mark the entrance to a sinus tract that may travel under the skin near the ear cartilage. These tracts are lined with squamous epithelium and may sequester to produce epithelial-lined subcutaneous cysts or may become infected, leading to cellulitis or abscess.

Lymph nodes at Surface: 1. Occipital (retroauricular) 2. Mastoid 3. Superficial Parotid 4. Deep Parotid 6. Infraauricular 7. Intraglandular parotid Facial Lymph Nodes: 8. Buccinator 9. Nasolabial 10. Mandibular 11. Anterior Cervical (Superficial jugular) 12. Superficial Cervical (External jugular)
 * 5. Preauricular **

A preauricular sinus can either happen by chance or you can inherit them. Over 50% of cases overall are unilateral which just means one ear or the other and are found to be by chance. It occurs more commonly on the right side (right ear). Bilateral meaning both sides of your head (both ears) are commonly found to be inherited. When preauricular sinus glands are inherited, the paten is incomplete autosomal dominance which reduces it by 85%. ======

ps....this is two pictures! I was serious about having them! media type="youtube" key="M-aUukFk-tY" height="315" width="420" This is exactly what will happen if you don't take care of your preauricular glands/sinus. This has never occurred to me however, I pay very close attention to keeping them clean. Sources:

 * Wikipost #1 – Genetics**

**Cyclopia** This birth defect doesn’t allow the orbits of the eye into two cavities. This happens in every 1 in 250 babies. The face will be missing or the nose will be non-functioning and that nose will either be above the eye or on the back of the head. Most babies don’t make it till birth and some are still born. There two children with Down Syndrome that have been born with one eye. Cyclopia is usually caused by genetic problems or toxins consumed by the mother. This is when the two eyes are suppressed into one. Which is the result in Cyclopia. (A) Phenotype cyclopia could be distinguished into five different groups when the eye pigmentation is developed. It is not only humans that can have trouble with cyclopia. Its actually very common in animals. There are reports of kittens being born with it regularly. However, the kittens tend not to survive and usually are either born dead or die within the first few hours of being born. Especially with the kitten, the poorly functioning nose may completely cut off breathing and cause suffocation. Other animals may have this condition and may die within a few days of birth rather than a few hours.  This picture is very unlikely that this kitten could have survived to this stage in life however, it is possible. This image however, is very realistic, cyclopia is commonly found in mammals. media type="youtube" key="wH4t2bq4mJI" height="19" width="420" This is a rare case considering it is not only large but is very unique. This rare shark has an obvious case of cyclopia.
