Incomplete Kawasaki disease in the 2-month-old infant: A case report.

RATIONALE

The diagnosis of Kawasaki disease (KD) is difficult and is often delayed for children whose age falls outside the typical age range of 6 months to 5 years, especially for those with incomplete KD (IKD) or atypical features.

PATIENT CONCERNS

A 2-month-20-day-old girl presented to our hospital with a chief complaint of intermittent fever for 1 day and 1 episode of seizure, with poor feeding and swelling of feet.

DIAGNOSIS

Until the appearance of red cracked lips, a diagnosis of IKD was considered. A rise in periungual desquamation of the hands confirmed the diagnosis.

INTERVENTIONS

Intravenous immunoglobulins were administered and aspirin and dipyridamole were used orally.

OUTCOME

The temperature, C-reactive protein, and erythrocyte sedimentation rate returned to normal level and there was no coronary artery lesion.

LESSONS

This case highlights that the diagnosis of IKD should be considered in children whose primary presentation is fever and neurologic features, lacking principal clinical findings, particularly those <6 months of age.
