The investigators will enroll 27 subjects with newly diagnosed or previously treated MCD (who have not previously received rituximab) requiring treatment (B symptoms or hemoglobin \\<10 g/dL). Subjects will be treated with four weekly doses of rituximab. High-risk subjects (defined as patients with Eastern Cooperative Oncology Group (ECOG) performance status \\>2 or hemoglobin \\<8 g/dL) will also receive etoposide chemotherapy. Subjects will be followed for one year for toxicity and two years for survival. The primary outcome will be safety, defined as the frequency of ≥Grade 3 treatment-related Common Terminology Criteria for Adverse Events (AEs). Secondary outcomes will be event-free survival (death, progression, or development of NHL) and 1- and 2-year overall survival (OS). The investigators also aim to compare the cost-effectiveness of first-line rituximab treatment for MCD in Malawi to chemotherapy (using the investigators' historical controls)."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.

Previous rituximab use for MCD.\n3. Second active malignancy requiring systemic therapy.\n4. If HIV negative and a) hepatitis B virus surface antigen positive or b) a combination of HepB core antibody positive and HepB surface antibody negative (indicative of chronic infection) unless on tenofovir or lamivudine. All HIV-infected patients must be on tenofovir or lamivudine as part of the inclusion criteria.\n5. Active infection requiring systemic therapy.\n6. Treatment with any investigational drug within 28 days prior to registration.\n7. More than 7 days of corticosteroids immediately prior to enrollment.
