Primary lymphoma of the conjunctiva is a rare type of cancer that affects the thin, transparent layer of tissue that covers the white part of the eye and the inner surface of the eyelids. It is a type of non-Hodgkin lymphoma, which is a cancer of the lymphatic system. Symptoms of primary lymphoma of the conjunctiva include redness, swelling, and pain in the eye, as well as blurred vision. Treatment typically involves chemotherapy and/or radiation therapy.

The most common symptom of primary lymphoma of the conjunctiva is a rapidly growing, painless, white or yellowish mass on the conjunctiva. Other symptoms may include redness, irritation, tearing, blurred vision, and a feeling of something in the eye.

The exact cause of primary lymphoma of the conjunctiva is unknown. However, it is believed to be associated with a weakened immune system, exposure to certain viruses, and genetic factors.

The primary treatment for primary lymphoma of the conjunctiva is usually radiation therapy. This may be combined with chemotherapy, depending on the type and stage of the lymphoma. Surgery may also be used to remove the affected area of the conjunctiva. In some cases, a combination of treatments may be used.

1. Exposure to ultraviolet radiation

3. Human immunodeficiency virus (HIV) infection
4. Chronic inflammation of the conjunctiva

Primary lymphoma of the conjunctiva is a rare form of cancer, and there is no standard treatment for it. Treatment options may include chemotherapy, radiation therapy, and/or surgery. The type of treatment used will depend on the type and stage of the cancer, as well as the patient's overall health.
