Dermoid cysts consist of keratinized epithelium and adnexal structures such as hair follicles, sweat glands, and sebaceous glands. They slowly enlarge with age. Dermoid cysts are histologically defined as surface epithelium encapsulating an inner lumen. They are well described in the literature as discrete, single masses, either circumscribed or dumbbell-shaped, with or without a longstanding fistula.

2005;24(2):145-8. Shields JA, Shields CL. Orbital cysts of childhood – classification, clinical features, and management. The commonest dermoid cysts are firm and smooth, mobile preseptal masses overlying the supero-temporal quadrant of the orbit and, less commonly, the supero-nasal quadrant. Many cysts have a variable periosteal attachment near the underlying fronto-zygomatic or fronto-ethmoidal sutures, but occasionally the dermoid will pass into or through defects in the neighbouring bone. Over a thirteen year period forty patients underwent surgery to remove an orbital dermoid cyst. Cysts which became manifest after the age of three years were deeper and larger than most that were Dermoid and epidermoid cysts of the orbit belong to choristomas, tumours that originate from the aberrant primordial tissue. 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.
