Felty Syndrome in a Patient Presenting With Bilateral Scleritis and Multiple Autoimmune Syndrome: A Case Report.

Autoimmune diseases can result in additional symptoms and complications impacting various organ systems beyond the joints. These can affect the eyes, skin, respiratory, cardiac, and renal systems. Recognizing and understanding these diverse manifestations, such as the severe eye issues seen in rheumatoid arthritis (RA) and the potentially life-threatening Felty syndrome, is crucial for clinicians to promptly identify and treat these conditions effectively. In this case presentation, we report on a patient admitted for bilateral scleritis, which was found to be secondary to multiple autoimmune syndrome type 3. During the patient's hospital stay, Felty syndrome was incidentally diagnosed due to the observed combination of RA, splenomegaly, and absolute neutropenia. Prompt recognition of this condition allowed the patient to receive appropriate care, including oral steroids, hydroxychloroquine, and methotrexate, decreasing the risk of severe complications.
