An epidermoid cyst is a benign cyst, developed out of ectodermal tissue. Histologically, it is made of a thin layer of squamous epithelium.
It's very common for women and can be found on the major or minor labia.
The more general term for an Epidermal Inclusion Cyst (which strictly means implantation of epidermal elements into the dermis), Epidermoid cyst includes cysts originating from the infundibular portion of the hair follicle.
The majority of Epidermal Inclusion Cysts do in fact originate from the infundibular portion of the hair follicle thus explaining the interchangeable, yet technically incorrect, use of these two terms.
These cysts are caused by a bacterium and form into a pimple-like shape.
It's very common for women and can be found on the major or minor labia. For some individuals, it doesn't even irritate. For others, it can hurt and when touched, it can release pus. If any of this occurs, its best to discuss it with a doctor.
In contrast to pilar cysts, epidermoid cysts usually present on parts of the body with relatively little hair.
Although they are not malignant, it is possible for malignant tumors to arise from them.
