Dermoid cyst orbit

It frequently consists of skin, hair follicles, and sweat glands, while other commonly found components include clumps of long hair, pockets of sebum, blood, fat, bone, nail, teeth, eyes, cartilage, and thyroid tissue. 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.

As they grow slowly, less than 25% of them are identified at birth, and they usually manifest in the first decade of life. Clinical features include a painless subcutaneous mass along the zygomaticofrontal and the frontoethmoidal sutures 1,3.

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 2010-07-01 · 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.

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.

A case of a giant dermoid cyst 01 the orbit associated with microphthalmia in a two-year old female child is reported. Clinical diagnosis of the condition was made when the child was two months old, although it had been observed at birth by the parents.

Unlike teratomas, these lesions are not neoplasms, but rather represent closed sacs lined by an ectodermal epithelium (, 2 –, 9). Samuels 4 in 1936, before this society, reported the histologic study of 13 dermoid cysts but failed to differentiate orbital from paraorbital growths. Many reports of isolated cases of oil, or dermoid.
