  • Title: Lethal Epstein-Barr virus associated NK/T-cell lymphoma with primary manifestation in the conjunctiva.
    Author: Widmer S, Tinguely M, Egli F, Thiel MA.
    Journal: Klin Monbl Augenheilkd; 2005 Mar; 222(3):255-7. PubMed ID: 15785994.
    Abstract:
    BACKGROUND: Lethal midline granulomas (LMG) are very rare angiocentric NK/T-cell lymphomas in association with Epstein-Barr virus. LMG are reported mainly in East Asia occurring in immune compromised patients. HISTORY AND SIGNS: A 41-year old male patient presented with a conjunctival swelling of his upper left eyelid. The lesion had increased over a period of 2 months despite topical corticosteroid treatment. Conjunctival biopsy revealed a highly malignant, CD3 + and BCL2 + extranodal T-cell lymphoma with features of an NK/T-cell origin (CD56 +, TIA + TCR-rearrangement: germline). All lymphoma cells were positive for Epstein-Barr virus RNA. The proliferation rate was highly elevated at 100 %. THERAPY AND OUTCOME: Systemic 1 (st) cycle chemotherapy with cyclophosphamide, doxorubicin, vincristin and prednisone resulted in a complete remission of the swelling within 4 days. However, one week later a massive conjunctival tumour reappeared with only partial regression after combined chemo- and radiotherapy. The patient died within a month because of untreatable pancytopenia due to malignant bone marrow infiltration. CONCLUSIONS: LMG is a rare but highly malignant Epstein-Barr virus associated NK/T-cell lymphoma that can occur in healthy, immune competent Caucasians. This is the first reported case of an LMG in an immune-competent Caucasian patient with primary ocular manifestation. The LMG has a high mortality rate despite systemic treatment and can be lethal within a few months or even weeks.
