Pathophysiology: Dermoid cysts are congenital choristomas that result from the sequestration of embryonic epithelium between orbital bones, usually along suture lines. These ectodermal tissues are "pinched off" in characteristic locations in the orbit and grow until they become clinically apparent (Sherman 1984).

As two suture lines of the skull close during embryonic development, dermal or epidermal elements may be pinched off and form cysts. These cysts occur adjacent to a suture line (this is shown in Dermoid tumors of the globe, which are solid formations, are relatively common, whereas true dermoid cysts of the orbit are of the rarest occurrence, probably being rarer than intra-ocular retinoblastoma or sarcoma. The typical location of such a cyst is in the upper temporal quadrant of the orbit, near the lacrimal gland. Kiratli H, Bilgic S, Sahin A, Tezel CG. Dermoid cyst of the lacrimal gland.

Complete surgical excision is curative. Excision of Orbital Dermoid Cysts via Upper Eyelid Incision: A Review of 24 Cases Rustu Kose Abstract Background: Dermoid cysts are abnormally located masses arising from abnormal involution of superficial ectoderm during closure of sutures between bones. Dermoid cysts are the most common orbital masses in childhood.

On December 15, 1937, an operation was performed for removal of the cyst by Dr. Emile Holman, using local anes thesia. The skin incision was just above the lower orbital rim and extended almost the entire extent from inner canthus to outer canthus. Dermoid cysts of the orbit are uncommon lesions that occur primarily in the pediatric population. Lesions extending into the frontal sinus have not been reported before in the literature. In adults, orbital dermoids are more likely to present with bone erosion, and therefore they should be considered in the differential diagnosis for orbital and frontal bone lesions extending into the frontal sinus.

Cyst: dermoid cyst of orbit. The more common location for a dermoid cyst of the orbit is the upper outer part of the orbit. In the photo, the patient presents with a dermoid cyst in the upper inner part of the orbit. Dermoid cysts normally do not cause exophthalmos because they lie in front of the orbital septum.

Clinically, they manifest as cystic movable formations mostly localized Dermoid cysts of the orbit are uncommon orbital tumours that occur primarily in the pediatric population. They are divided into deep and superficial lesions with deep lesions presenting later in life. Depending on the location, size, the patient may present proptosis, diplopia, and restriction of eye movements. Orbital dermoid is an egg-shaped mass formed under the skin adjacent to the bones of the eye socket. The mass is smooth, yet firm and non tender. Dermoids can remodel the bone adjacent to them so they can comfortably sit in a depression in the bone.
