Conjunctival Inflammation and Panuveitis as Manifestations of Ig-G4-Related Disease: A Case Report.

PURPOSE

To report a case of isolated conjunctival inflammation as initial manifestation of IgG4-related disease and subsequent development of panuveitis.

CASE REPORT

A 75-year-old female presented with a diffuse mass lesion in the temporal area of the left eye, involving the conjunctiva, and an abscessed corneal ulcer. An incisional biopsy was diagnostic of IgG4-related disease with an elevated IgG4/IgG ratio (>40%) and the presence of >10 cells that tested positive for IgG4/CGA. No other ocular, orbital or systemic manifestations were noted at the time of diagnosis. After a year of treatment with topical dexamethasone, oral prednisone, and methotrexate, the patient developed panuveitis, which was controlled by increasing steroids and switching to rituximab.

CONCLUSION

IgG4-related disease is a rare entity that can be particularly challenging to diagnose if it manifests in an atypical manner. Continuous follow-up of patients is crucial as relapses and worsening of symptoms can occur despite treatment.
