Conclusion:
KD is a rare condition, and it should be considered in differential diagnoses of tender lymphadenopathy, especially lymphadenopathy localized to the cervical region and recurrent fever with AIH. Although the disease takes a self-limiting clinical course in most cases, we reported a case of KD with a prolonged relapse of ten years. Our case emphasizes the association of KD with autoimmune conditions other than SLE. Full recovery with a good response to corticosteroid regimen was achieved after the recurrence; therefore, considering the recurrence of KD, long-term follow-up of patients with KD should be implemented.
