A Case Report of Conjunctival Extranodal Marginal Zone Lymphoma Treated with Intralesional Rituximab Injection Therapy

To describe the safety and efficacy of intralesional rituximab (anti-CD 20 monoclonal antibody) therapy in a patient with conjunctival extranodal marginal zone lymphoma.A single case report from a tertiary referral center.A 43 years old female patient with low-grade conjunctival extranodal marginal zone lymphoma who was completely and safely treated with intralesional rituximab therapy was presented. After four injections per week, intralesional rituximab injections were given monthly, and the treatment was completed in 6 months. Near-total regression was achieved at the end of the tenth cycle. No recurrence was observed during the 20-month follow-up period.The intralesional rituximab is a cost-effective and well-tolerated treatment for low-grade conjunctival lymphoma. The intralesional rituximab therapy may be prefer in the patients with low grade conjunctival lymphoma instead of radiotherapy. There will be needed further researches in this area.
