Dermoid cysts originate from totipotential germ cells ( which are present at birth ) that differentiate abnormally, developing characteristics of mature dermal cells.

A "'dermoid cyst "'is a teratoma of a cystic nature that contains an array of developmentally mature, solid tissues.
23.
A dermoid cyst is a mature cystic teratoma containing hair ( sometimes very abundant ) and other structures characteristic of normal skin and other tissues derived from the ectoderm.
24.
The dermoid sinus gene is believed by some to be recessive, meaning that the animal must receive one defective gene from each parent in order to develop the condition.
25.
When, due to an error of diagnosis, the technique is applied to a dermoid cyst ( teratoma ) or other tumor, the risk of subsequent tumor recurrence and cancer is much increased.

Another type of XX gonadal dysgenesis is known as 46, XX gonadal dysgenesis epibulbar dermoid, which follows the similar symptoms as the regular syndrome, though it also shows signs of epibulbar dermoid ( eye disorder ).

28.
As dermoid cysts grow slowly and contain mature tissue, this type of cystic teratoma is nearly always malignant, a squamous cell carcinoma usually develops in adults, while infants and children usually present with an endodermal sinus tumor.
29.
In any case, because of the genetic nature of this potentially dangerous condition, most breeders and veterinarians advise against breeding animals that have a dermoid sinus, or have a parent that is known to carry the gene.
30.
They occur when skin cells and things like hair, sweat glands, oil glands or fatty tissue get trapped in the skin as a baby grows in the womb . Dermoid cysts are present at birth ( congenital ) and are common.
