Kawasaki disease in healthy young adult

Area of Science:

• Pediatrics
• Rheumatology
• Infectious Diseases

Background:

• Kawasaki disease (KD), also known as mucocutaneous lymph node syndrome, is an acute febrile illness predominantly affecting young children.
• Diagnosis typically requires fever lasting ≥5 days plus specific clinical criteria, excluding other known causes.

Observation:

• This report details a 26-year-old woman who met the diagnostic criteria for Kawasaki disease.
• The patient presented with prolonged fever and characteristic symptoms including conjunctival injection, mucous membrane involvement, extremity changes, rash, and lymphadenopathy.

Findings:

• The adult patient fulfilled the standard diagnostic criteria for Kawasaki disease, despite its rarity in this age group.
• The clinical presentation included key features such as fever, conjunctivitis, oral mucosal changes, extremity edema/desquamation, rash, and cervical lymphadenopathy.

Implications:

• This case underscores the necessity of considering Kawasaki disease in the differential diagnosis of febrile illnesses in adults presenting with compatible symptoms.
• Recognizing KD in adults is crucial for timely treatment and preventing potential cardiac complications, such as coronary artery aneurysms.
• Further research may be warranted to understand the epidemiology and clinical variations of Kawasaki disease in adult populations.
