Diagnosis by polymerase chain reaction of ocular posttransplant lymphoproliferative disorder after pediatric renal transplantation.

PURPOSE: To report diagnosis by polymerase chain reaction of intraocular posttransplant lymphoproliferative disorder in a pediatric renal transplant patient.

DESIGN

Observational case report.

METHODS

Retrospective review.

RESULTS

An 11-year-old girl developed infectious mononucleosis 15 months after renal transplantation for focal segmental sclerosis. Papillitis and hypopyon uveitis developed 8 months later, followed by iris nodules. Diagnosis of intraocular posttransplant lymphoproliferative disorder was made by polymerase chain reaction of aqueous humor for Epstein-Barr virus and confirmed by histopathology of an iris biopsy specimen. Infiltrating iris lymphocytes in the biopsy specimen were positive for Epstein-Barr DNA. Polymerase chain reaction also revealed gene rearrangement of the variable region of the heavy immunoglobulin chain, consistent with a monoclonal B-lymphocyte population. Iris nodules resolved with reduction in immunosuppressive medication.

CONCLUSION

Polymerase chain reaction for Epstein-Barr virus may be helpful in diagnosis of intraocular posttransplant lymphoproliferative disorder.
