Abstract

Background:

The increased risk of developing lymphoproliferative disorders, mainly linked with Epstein–Barr virus infection, is well documented in patients with cyclosporin-induced immunosuppression following organ transplantation. Lymphoproliferative disease is extremely rare in the non-transplant setting.

Methods:

We present the first published case of non-Epstein–Barr virus associated lymphoproliferative disease in a patient receiving long-standing cyclosporin therapy for psoriatic arthritis, which presented as a recurrent nasopharyngeal mass.

Results:

Histological examination showed lymphoid hyperplasia in repeated biopsies. Macroscopic clearance was persistently followed by aggressive recurrence. Spontaneous regression occurred upon cyclosporin withdrawal.

Conclusion:

This rare complication of cyclosporin therapy in non-transplant patients is highlighted from an otolaryngological perspective, as the sole presentation may be a recurrent nasopharyngeal mass. Repeated biopsies showing lymphoid hyperplasia, together with aggressive recurrence, should prompt immediate drug withdrawal to reduce immunosuppression and promote spontaneous regression.
