A standard treatment for patients with primary intraocular lymphoma (PIOL) remains unclear. This study retrospectively analyzed the clinical features and outcomes of 19 patients with PIOL who were treated with a first-line therapy comprising combined intravenous high-dose methotrexate and intravitreal methotrexate between January 2003 and December 2013. Thirteen (68.4 %) patients were female, and the median age at diagnosis was 57 (39-77 years). Diagnoses were based on the identification of abnormal lymphoid cells in vitreous fluid. Ten (52.6 %) patients had bilateral eye involvement, and six had concurrent central nervous system (CNS) involvement. All 19 patients achieved complete remission (CR) as confirmed by cytological examination of vitreous and cerebrospinal fluid and brain imaging if CNS was involved. Patients with concurrent brain involvement required a longer time to achieve CR. However, the duration of complete remission did not differ between patients with and without CNS involvement. The 5-year overall survival rate was 55.8 % for the total cohort and was higher (68.8 %) in patients with isolated PIOL than in those with concurrent CNS involvement. In all patients, methotrexate treatment was well tolerated, with manageable side effects. We conclude that combined intravitreal methotrexate and systemic high-dose methotrexate treatment is effective in patients with PIOL.

Objectives:Primary hepatic lymphoma is an uncommon cause of hepatic space-occupying lesions.Methods:We describe the case of a 73-year-old man with primary hepatic lymphoma, who presented with a low-grade fever and lower limb weakness which had progressed in the past 2 months.Results:Abdominal ultrasound and computed tomography showed multiple small hepatic tumors. Echo-guided biopsy of the hepatic tumor demonstrated primary hepatic diffuse large B cell lymphoma. Moreover, bone marrow was uninvolved, but the bone marrow smear disclosed hemophagocytosis, which is uncommon in diffuse large B cell lymphoma. Chemotherapy with bendamustine and rituximab treatment was initiated with a dramatic response: hepatic tumors markedly shrank in size shown by follow-up computed tomography and the patient returned to his normal life. Nevertheless, the response was sustained for only 8 months. Finally, the disease resisted further chemotherapy and this patient died of a severe Klebsiella pneumoniae infection.Conclusion:Chemotherapy with bendamustine and rituximab has shown a dramatic, but not durable, response in the present case with old age and multiple comorbidities.
