Abstract

We report a rare case of Epstein-Barr virus (EBV)-positive polymorphic B-cell lymphoproliferative disorder (LPD) involving the lacrimal gland of a 28-year-old, apparently immunocompetent woman. She presented with a chief complaint of orbital swelling and tenderness and was found to have a lesion involving the right lacrimal gland and distal superior and lateral rectus muscles. Histology of the lesion revealed histiocytes with pleomorphic nuclei, reactive lymphocytes, and scattered cells that resembled the Reed-Sternberg (R-S) cells of classical Hodgkin lymphoma. The R-S-like cells were positive for PAX5 and CD30 and negative for CD15, supporting a diagnosis of polymorphic B-cell LPD. In situ hybridization for EBV-encoded RNA demonstrated the presence of EBV. Most EBV-positive polymorphic B-cell LPDs are associated with immunodeficiency. However, the patient described is HIV-negative and has no identifiable defects in immunoglobulin levels or cell-mediated immunity. This raises the question of whether she has an underlying immunodeficiency resulting from subtle changes in T-cell physiology, or whether chronic EBV infection contributed to her immune dysfunction through an unclear mechanism. The orbital mass partially regressed with chemotherapy, and the patient has done well clinically with no recurrence of this EBV-LPD for over 2 years.
