What is Lipodermoid cyst?
What is Lipodermoid cyst?
Ocular lipodermoid cysts and solid dermoid tumors are choristomas which are described as normal tissue growth in an abnormal location. Congenital epibulbar lipodermoid comprises adipose tissue that is covered by connective tissue.
What is a Dermolipoma?
Background: Dermolipoma is an uncommon benign tumor, congenitally occurring on the conjunctiva, and may be present at other sites. The appearance of dermolipoma closely resembles orbital fat prolapse and limbal dermoid, and therefore it is necessary to take this into account in diagnosis.
What causes Dermolipoma?
Dermolipoma is believed to be a congenital solid choristoma that is derived from an ectopia of the ectoderm to the conjunctiva, probably due to sequestration at the time of embryonic development of the eyelid.
What is a conjunctival dermoid?
Conjunctival limbal dermoids are lined by nonkeratinized conjunctival epithelium with goblet cells and appear as firm, subcutaneous masses. They sometimes contain dermal appendages, such as hair shafts, sebaceous glands and sweat glands.
What is a neoplasm of the eye?
Eye neoplasms can affect all parts of the eye, and can be a benign tumor or a malignant tumor (cancer). Eye cancers can be primary (starts within the eye) or metastatic cancer (spread to the eye from another organ). The two most common cancers that spread to the eye from another organ are breast cancer and lung cancer.
Are orbital tumors cancerous?
Orbital tumors can be benign or malignant, and they can be either primary (meaning the tumor originates there) or metastatic (meaning the tumor represents the spread of another cancer elsewhere in the body). Some orbital tumors occur most commonly in children, other types are more often diagnosed in adults.
What is orbital fat prolapse?
Subconjunctival prolapse of orbital fat is an uncommon clinical entity in which intraconal orbital fat herniates into the subconjunctival space. Its diagnosis is mainly clinical in character and usually based on palpation, patient clinical history, and lesion features along with a slit lamp examination.
How are conjunctival cysts treated?
Non-Surgical Treatment for Conjunctival Cysts
- Artificial tears or other lubricating drops.
- Prescription steroid drops to ease inflammation.
- Warm compresses, which may cause the cyst to break.
- Antibiotic ointment prescribed by a doctor, in case of infection.
What is ocular dermoid?
Dermoids of the eye, more commonly known as ocular dermoids, are simply normal tissue in an abnormal place. In this case, tissue grows on the cornea or the conjunctiva (the white of your dog’s eye and eyelid.)
Can limbal dermoid be removed?
The method of choice to treat a limbal dermoid is surgical excision. The use of amniotic membrane transplantation in the removal of a limbal dermoid has recently been described by others.
What is the most common neoplasm that affects the eye?
The most common malignant primary intraocular tumor in adults is uveal melanoma. These tumors can occur in the choroid, iris and ciliary body. The latter are sometimes called iris or ciliary body melanoma.
Do you have to have surgery for lipodermoid?
Unless these lesions enlarge dramatically, they should be observed without surgery, since excision may be complicated by ptosis, restricted ocular motility, or damage to the globe. ” Reference: Pavan-Langston, Manual of Ocular Diagnosis and Therapy, second edition, p.61, 1988.
How are lipodermoids treated in the left eye?
Lipodermoid on the left eye. Prior to surgery we have obtained a very detailed patient history and we have performed a thorough ophthalmologic examination, after which we have been able to have the exact diagnosis.
What kind of tumor is a lipodermoid tumor?
Lipodermoids are abnormal epibulbar growths of the adipose tissue. Epibulbar dermoids are benign congenital tumors that contain choristomatous tissue (choristomas are congenital overgrowth of normal tissue in abnormal locations) [ 1 ].
Where is the dissection of the lipodermoid carried out?
On the posterior surface of the lipodermoid, the dissection will be carried out between the lipodermoid and the Tenon’s. One should be careful of dissection too close to the lateral rectus muscle which could result in post-operative strabismus. If necessary, a muscle hook can be placed to identify the muscle.
