PurposeTo provide a detailed immunohistochemical analysis of juvenile idiopathic arthritis (JIA)-associated anterior uveitis.DesignInterventional case report.ParticipantOne patient.InterventionA 12-year-old patient had recurrent pauciarticular JIA and smoldering anterior uveitis in the right eye. Despite treatment with local and systemic corticosteroids and an anti–tumor necrosis factor agent, the right eye became hypotonous and painful and eventually was enucleated. The clinical history and histopathologic and immunohistochemical analyses of the enucleated globe were reviewed.Main Outcome MeasuresHistopathologic and immunohistochemical features of JIA-associated anterior uveitis.ResultsThe iris and ciliary body showed nongranulomatous chronic inflammation predominantly made up of plasma cells, Russell bodies, and plasmacytoid lymphocytes. The ciliary processes and pars plana ciliaris showed focal aggregates of CD20-positive cells with several CD3- and CD8-positive cells and occasional CD4- and CD68-positive cells. Pancytokeratin stain showed ciliary epithelial proliferation admixed with lymphocytes. The iris revealed κ-positive cells within the stroma and λ-positive cells on the surface. The iris infiltrate primarily was made up of immunoglobulin (Ig) G-positive cells with occasional IgA- and IgM-positive cells. The anterior chamber exudate was mainly positive for IgG and IgA.ConclusionsThe immunohistochemical findings suggest that JIA-associated nongranulomatous iridocyclitis is a primarily B-cell-infiltrative process.Financial Disclosure(s)The authors have no proprietary or commercial interest in any materials discussed in this article.
