Two cases of adult-onset Still's disease with orbital inflammatory lesions originating from the lacrimal gland.

Resum
Orbital inflammation has been rarely associated with adult-onset Still's disease (AOSD). We herein describe two AOSD patients who developed lacrimal gland enlargement with inflammation spreading to the contiguous tissues in the orbit. Case 1 was a 26-year-old woman who developed bilateral eyelid swelling while taking prednisolone (22.5 mg/day) for AOSD. The swelling of the eyelid worsened after other symptoms emerged, such as a fever, a rash, and arthritis. The laboratory findings, including leukocytosis, liver dysfunction, and ferritin elevation, also suggested an AOSD flare-up. Case 2 was a 62-year-old woman who presented with left eyelid swelling. She was diagnosed with AOSD at 45 years of age but sustained remission. During admission, she subsequently developed a fever, a rash, arthritis, lymphadenopathy, and ocular hyperemia. AOSD was suspected from the clinical course. We speculate that dacryoadenitis and orbital inflammation are manifestations of AOSD.
