Fuchs syndrome: a case of fever, mucositis and conjunctivitis

Description

A 5-year-old boy presented with fever and cough of 2 weeks' duration, conjunctivitis and lip swelling with blistering for 6 days, and 1 day of skin rash. His past medical history was significant for incomplete Kawasaki disease (KD) at 3 years of age with no cardiac sequelae.
