Atypical Kawasaki in a 15-Month-Old Infant: Diagnosis Is Not Always Easy

Introduction: Kawasaki disease (KD) is an acute systemic febrile vasculitis in young children and infants, which affects medium and small caliber vessels. Case report: A 15-month-old male patient who initially consulted for left cervical lymphadenopathy against a background of fever. The diagnosis of an adenophlegmon has been suspected. Outpatient treatment was administered. The course was marked by the persistence of fever and regression of lymphadenopathy. Clinical examination during the check found cheilitis and peeling of the perineum with biological inflammatory syndrome. The patient received aspirin anti-inflammatory dose and perfusion of immunoglobulins with good progress. Conclusion: In the case of an adenopathy in infants associated with prolonged fever, one should always be wary of a Kawasaki even in the absence of other clinical criteria.
