Postsplenectomy Kawasaki disease in a 17-year‑old male

Kawasaki disease (KD) is characterized with an acute systemic vasculitis of the
medium- and small-sized vessels. This disease mainly involves children within the age of 6
months to 5 years and it is often self-limited and patients seem to recover well; however, it may
lead to devastating and fatal cardiovascular complications such as coronary artery aneurysm.
Thus, early diagnosis and appropriate management of this disease have a significant effect on
improving the prognosis and preventing its serious complications. Adult-onset KD (AKD) is rare
and often misdiagnosed. Here we report a rare case of KD that occurred in a 17-year-old young
adult who presented 4 weeks post splenectomy, with clinical signs and symptoms consistent
with AKD. This may potentially highlight the association of AKD with infectious etiologies
