Kikuchi-Fujimoto Disease in Patients with Sjögren’s Syndrome

Sjögren’s syndrome is a chronic autoimmune exocrinopathy associated with dry eyes and dry mouth as major clinical manifestations. It is characterized by lymphocytic infiltration of lacrimal and salivary glands and autoantibody production, especially anti-Ro (or SSA) and anti-La (or SSB). Lymphoproliferative disorders are a feature of Sjögren’s syndrome, and can be considered an extraglandular manifestation of the disease. Kikuchi-Fujimoto disease or histiocytic necrotizing lymphadenitis is a rare form of lymphadenitis. It is reported more often in young adult women with localized lymphadenopathy (usually cervical), fever, rashes, and leukopenia. It is a self-limiting disease with resolution within 1 4 months in almost all patients. Sjögren’s syndrome has been reported in patients with other systemic diseases including SLE and lymphomas. Here we present a patient with Kikuchi-Fujimoto disease who developed Sjögren’s Syndrome 8 years after her diagnosis of Kikuchi-Fujimoto disease.
