Kawasaki disease with peritonsillar abscess as the first symptom:A case report

摘要

BACKGROUND Kawasaki disease(KD),also known as mucocutaneous lymph node syndrome,is an acute,self-limiting vasculitis of unknown aetiology that mainly involves the medium and small arteries and can lead to serious cardiovascular complications,with a 25%incidence of coronary artery aneurysms.Periton–Sillar abscesses are a rare symptom of KD and is easily misdiagnosed at its early stages.CASE SUMMARY A 5-year-old boy who presented to a community hospital with a 3-d fever,difficulty in opening his mouth,and neck pain and was originally treated for throat infection without improvement.On the basis of laboratory tests,ultrasound of submandibular and superficial lymph nodes and computed tomography of the neck,the clinician diagnosed the periamygdala abscess and sepsis that did not resolve after antibiotic therapy.On the fifth day of admission,the child developed conjunctival congestion,prune tongue,perianal congestion and desquamation,and slightly stiff and swollen bunions on both feet.A diagnosis of KD was reached with complete remission after intravenous immunoglobulin treatment.CONCLUSION Children with neck pain,lymph node enlargement,or airway obstruction as the main manifestations are poorly treated with intravenous broad-spectrum antibiotics.Clinicians should not rush invasive operations such as neck puncture,incision,and drainage and should be alert for KD when it cannot be explained by deep neck space infection and early treatment with aspirin combined with gammaglobulin.
