How common is conjunctival lymphoma?

Epidemiology. Approximately 2-8% of extranodal lymphomas occur within the adnexa of the eye [1]. Of these, approximately 25% occur within the conjunctiva [2]. Estimated incidence of conjunctival lymphoma is 2-4/1,000,000 [1].

How common is ocular lymphoma?

Intraocular lymphoma is rare, with fewer than 200 cases being reported. This type of lymphoma is estimated to represent 1% of NHLs, 1% of intracranial tumors, and less than 1% of intraocular tumors.

Is conjunctival lymphoma cancerous?

Lymphoma is among the most common malignant conjunctival tumor. As the symptoms are often minimal, it is imperative for the general ophthalmologist to be alert for the characteristic “salmon patch” appearance of these neoplasms or to suspect lymphoma in individuals with unexplained chronic follicular conjunctivitis.

Is lymphoma of the eye curable?

Treatment. Ocular lymphomas don’t improve on their own. Because of the nonspecific nature of primary intraocular lymphoma presentation, the condition is a diagnostic challenge. The prognosis for this condition remains poor with a five-year mortality of less than 25%.

Can you get lymphoma in your eye?

Lymphoma is a cancer that originates in white blood cells called lymphatic cells. When lymphoma develops in the eye, it is called primary intraocular lymphoma (PIOL), and it is almost always a type of lymphoma called non-Hodgkin’s B cell lymphoma.

Is ocular lymphoma hereditary?

Genetics may also play a role in the development of ocular lymphoma. Some people may inherit a gene from their parents that increases the chance of developing this type of cancer.

How is ocular lymphoma diagnosed?

The diagnosis of intraocular lymphoma is typically made by removal of cells (vitrectomy biopsy) from the eye with subsequent cytopathologic evaluation. Lymphoma biopsy should be performed at a center with ophthalmic pathology services used to working with small specimens.

What is conjunctival melanoma?

Abstract. Conjunctival malignant melanoma is a pigmented lesion of the ocular surface. It is an uncommon but potentially devastating tumor that may invade the local tissues of the eye, spread systemically through lymphatic drainage and hematogenous spread, and recur in spite of treatment.

What is conjunctival amyloidosis?

Conjunctival amyloidosis is an uncommon condition which usually arises secondary to chronic infection or trauma to the eye. It is rare to find significant deposits of amyloid involving the conjunctiva alone in the absence of a known antecedent infective, traumatic or hereditofamilial disorder.

What is conjunctival hemangioma?

Conjunctival capillary hemangioma is a rapidly developing tumor derived from endothelial cells that has rarely been reported in patients over 60 years old [3, 6]. Most cases of reported conjunctival hemangiomas are congenital, asymptomatic, and said to involute by age seven [6].

How does ocular melanoma start?

Doctors know that eye melanoma occurs when errors develop in the DNA of healthy eye cells. The DNA errors tell the cells to grow and multiply out of control, so the mutated cells go on living when they would normally die. The mutated cells accumulate in the eye and form an eye melanoma.
