Orbital lymphoma

Orbital Lymphoma

Orbital lymphoma (/ɔːrˈbaɪtəl ˈlɪmfəʊmə/) is a type of cancer that occurs in the lymphatic system, specifically in the orbit (eye socket).

Etymology

The term "Orbital lymphoma" is derived from two words. "Orbital" comes from the Latin word "orbita" which means "track or path", referring to the eye socket. "Lymphoma" is derived from the Latin word "lympha" meaning "water", and the Greek word "oma" meaning "disease or tumor".

Definition

Orbital lymphoma is a form of non-Hodgkin's lymphoma that primarily affects the orbit. It is a rare disease, accounting for only 1% of all lymphomas. The most common type of orbital lymphoma is marginal zone B-cell lymphoma, also known as MALT lymphoma.

Symptoms

Symptoms of orbital lymphoma may include proptosis (bulging eyes), diplopia (double vision), red eye, and vision loss. Some patients may also experience pain or discomfort in the eye area.

Diagnosis

Diagnosis of orbital lymphoma typically involves a combination of medical history, physical examination, imaging studies, and biopsy. Imaging studies such as CT scan or MRI can help to identify the location and extent of the tumor. A biopsy is necessary to confirm the diagnosis and determine the type of lymphoma.

Treatment

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

Prognosis

The prognosis for patients with 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 response to treatment.
