Ocular adnexal lymphomas: a review.

Area of Science:

• Ophthalmology
• Hematology
• Oncology

Background:

• Ocular adnexal lymphomas represent a small fraction of non-Hodgkin lymphomas and extranodal lymphomas.
• The majority are primary extranodal lymphomas, with mucosa-associated lymphoid tissue (MALT) lymphoma being the most common type (up to 80%).

Purpose of the Study:

• To provide a comprehensive review of ocular adnexal lymphomas.
• To cover incidence, histology, immunophenotyping, molecular and cytogenetic advances, clinical features, outcomes, and prognostic factors.
• To discuss associations with Chlamydia psittaci and IgG4-related sclerosing disease, and review treatment modalities.

Main Methods:

• Literature review encompassing incidence, histology, immunophenotyping, molecular/cytogenetic data, clinical features, and outcomes.
• Discussion of prognostic factors and specific associations (Chlamydia psittaci, IgG4-related disease).
• Review of traditional therapies (surgery, radiotherapy, chemotherapy) and novel treatments (immunotherapy, radioimmunotherapy).

Main Results:

• Ocular adnexal lymphomas are a heterogeneous group, predominantly MALT lymphomas.
• Recent advances in molecular and cytogenetics are shaping understanding and potentially treatment.
• Associations with specific infections and conditions are increasingly recognized.

Conclusions:

• A thorough understanding of ocular adnexal lymphomas requires integrating incidence, histology, molecular data, and clinical presentation.
• Emerging associations and novel therapies offer new avenues for patient management.
• Multidisciplinary approaches are crucial for optimizing outcomes in these rare malignancies.
