Even though patients with lymphoma sometimes present with malignant pleural effusion, chylous effusion is rarely encountered as a presenting feature in such patients. We present a 47-year-old woman diagnosed as follicular lymphoma who presented with chylothorax. Complete response to combination chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone was achieved.
