The ones in and around the eye are usually comprised of skin, hair, and/or fat [See figure 1]. Fig. 1: A dermoid is an overgrowth of normal, non-cancerous tissue in an abnormal location. Communication of these lesions with the central nervous system is rare and occurs in the nasal region. There are few clinical reports of temporal dermoid cysts presenting with intracranial extension, and we present a 15-year-old girl with a fronto-orbital dermoid cyst with intracranial extension and bone erosion. Orbital dermoid cyst may cause local complications due to mass effect. Giant orbital cysts may cause lo cal deformity of the bone and ocular motility prob lems (Reim et a!., 1975).

Dermoid Cyst WHAT IS A DERMOID? A dermoid is an overgrowth of normal, non-cancerous tissue in an abnormal location. Dermoids occur all over the body. The ones in and around the eye are usually comprised of skin, hair, and/or fat [See figure 1]. Fig. 1: A dermoid is an overgrowth of normal, non-cancerous tissue in an abnormal location.
dermoid cyst. DISCUSSION Dermoid cysts within the ocular region are thought to arise from sequestered benign ectodermal tissue, often at suture lines. The most common involved suture lines are the zygomatico-frontal suture in 2/3 and the fronto-ethmoidal suture in 1/3 of patients [4,5] .Orbital dermoids frequently have an intracranial extension.
1993). The cyst is a congenital lesion that forms from epithelial cells that are trapped during embryogenesis beneath the surface epithelium, often near bony structures.
30 Dec 2015 Orbital dermoid is a congenital benign cystic teratoma (choristoma) that originates from aberrant ectodermal tissue. In these tumours, there is

We describe a case of a dermoid cyst involving the orbit and frontal sinus of an adult treated at our tertiary referral center, and we review the literature on dermoid cysts of the orbit and frontal sinus. A 28-year-old Caucasian man presented with right-sided supraorbital swelling …
Some orbital dermoid cysts extend into the anterior and middle cranial fossae, into the nasal cavity, andmaybeattached to the optic-nerve sheath in the apex of the orbit. Whenthe dermoid has eroded bone the radiographic changes are diagnostic; a well-defined translucent area is surrounded by bone of increased density. What does an orbital dermoid look like? An orbital dermoid presents as an egg-shaped mass under the skin adjacent to the bones of the eye socket. The mass is smooth, firm, and not painful.

Patrick DeRespinis MD Pediatric Ophthalmology | Residency: New Jersey Medical School | Fellowship:Manahattan Eye, Ear & Throat Hospital Author of " Super Si orbital region, these cysts most commonly arise near the developing sutures of the orbital bones (5,8). Epidermoid cysts are thought to develop later in embryonic life, after the ectodermal cells become committed to a single cell type. They are lined only by squamous epithelium. In contrast, dermoid inclusion cysts have a more complex Dermoid cysts are common periorbital lesions.

Orbital dermoid cysts Laterally a tail of the cyst extends through the lateral wall of the orbit curving around the margin of the orbital rim deep to the temporalis. Posteriorly the bone is deficient in a number of areas with the cyst communicating with the middle cranial fossa with no evidence of extension into the intracranial compartment, and no changes in the Dermoid cysts account for about 3-9% of all orbital masses and 0.04-0.6% of primary orbital tumors. The frequent site of origin is the superotemporal quadrant of orbit.
