Abstract
ABSTRACT
An epidermoid cyst is one of the most common benign cysts of the skin. The cyst is
filled with keratin flakes and its wall is composed of keratinized, stratified, squamous
epithelium. Epidermoid cysts can occur anywhere on the body, usually along the
lines of embryonic fusion and mostly on the face, scalp, neck, chest, and upper
back. Around 80% of the epidermoid cysts are seen in ovaries and testicles whereas,
in the head and neck, they account for only about 7% and 1.6% of epidermoid
cysts are reported in the oral cavity. The condition can be congenital or acquired.
Congenital causes are rare and may be caused by the entrapment of ectodermal
elements intradermally or subcutaneously during embryogenesis. Acquired causes
of an epidermoid cyst may result from traumatic or iatrogenic implantation of
epithelial cells into the dermal layer or from obstruction of a pilosebaceous unit in
the hair follicle. Surgical excision completes the treatment.
