Orbital lymphoma

Orbital lymphoma is a type of cancer that occurs in the lymphatic system, specifically in the orbit, the bony cavity containing the eye. It is a rare condition, accounting for only 1% of all lymphomas, but it is the most common primary orbital malignancy.

Symptoms

The most common symptoms of orbital lymphoma include a noticeable mass or swelling in the eye area, diplopia (double vision), and proptosis (bulging of the eye). Other symptoms may include redness, pain, and impaired eye movement.

Causes

The exact cause of orbital lymphoma is unknown. However, it is believed to be related to the body's immune response, and may be associated with certain autoimmune diseases and infections.

Diagnosis

Diagnosis of orbital lymphoma typically involves a combination of history taking, physical examination, imaging studies such as CT or MRI, and biopsy of the affected tissue.

Treatment

Treatment for orbital lymphoma usually involves radiation therapy, chemotherapy, or a combination of both. The choice of treatment depends on the stage and type of the lymphoma, as well as the patient's overall health.

Prognosis

The prognosis for orbital lymphoma is generally good, with a high rate of long-term survival. However, the prognosis can vary depending on the type and stage of the lymphoma, as well as the patient's overall health.
