Orbital lymphoma
Orbital Lymphoma[edit | edit source]
Orbital lymphoma is a type of non-Hodgkin lymphoma that occurs in the orbit, the bony cavity in the skull where the eye and its appendages are situated. It is a rare condition that can affect the eye socket, leading to various ocular and systemic symptoms.
Pathophysiology[edit | edit source]
Orbital lymphoma is characterized by the proliferation of malignant lymphocytes within the orbital tissues. The most common type of orbital lymphoma is mucosa-associated lymphoid tissue (MALT) lymphoma, but other types such as diffuse large B-cell lymphoma and follicular lymphoma can also occur.
Clinical Presentation[edit | edit source]
Patients with orbital lymphoma may present with a variety of symptoms, including:
- Proptosis (bulging of the eye)
- Diplopia (double vision)
- Ptosis (drooping of the eyelid)
- Vision impairment
- Periorbital swelling
These symptoms result from the mass effect of the lymphoma within the confined space of the orbit.
Diagnosis[edit | edit source]
The diagnosis of orbital lymphoma typically involves:
- Clinical examination
- Imaging studies such as CT scan or MRI of the orbit
- Biopsy of the orbital mass for histopathological examination
Treatment[edit | edit source]
Treatment options for orbital lymphoma depend on the type and stage of the lymphoma and may include:
In some cases, a combination of these treatments may be used to achieve the best outcome.
Prognosis[edit | edit source]
The prognosis for patients with orbital lymphoma varies depending on the type and stage of the disease. MALT lymphoma generally has a good prognosis with appropriate treatment, while more aggressive types like diffuse large B-cell lymphoma may have a more guarded prognosis.
