Recalcitrant infectious uveoscleritis: A case report of a coinfection by Epstein-Barr virus and Talaromyces marneffei

INTRODUCTION AND IMPORTANCE: In an immunocompromised patient, there has never been a report of Epstein-Barr virus (EBV) and Talaromyces marneffei co-infection. Treatment with intravenous ganciclovir for EBV-associated uveitis has only been explored in a few cases. CASE PRESENTATION: A 47-year-old HIV-positive female presented with scleral nodule and vascularized iris tumor in the left eye. After the ancillary laboratory workup, EBV was detected by polymerase chain reaction on aqueous humor and scleral tissue analysis. The lesion subsided completely with systemic and local ganciclovir therapy. Subsequently, recurrent scleral nodule with iris plaque developed and was pathologically diagnosed as Talaromyces marneffei. The employed treatment, including intravenous amphotericin B and intracameral amphotericin B injection, was successful in attaining a significant regression of the lesion. CLINICAL DISCUSSION: Although EBV treatment is debatable, our combination of systemic and local ganciclovir therapy demonstrated regression of EBV-caused scleral nodule and iris plaque. The organism's identification was complicated by Talaromyces marneffei, but it was easily treated. CONCLUSIONS: In HIV-infected patients, EBV-associated sclerouveitis can be successfully treated with systemic and local ganciclovir therapy, and there is a possibility of coinfection with Talaromyces marneffei.
