Plaque psoriasis following Kawasaki disease and varicella

Area of Science:

• Pediatrics
• Dermatology
• Infectious Diseases

Background:

• Kawasaki disease is an acute febrile illness primarily affecting young children.
• Psoriasis is a chronic autoimmune condition.
• Varicella (chickenpox) is a common viral infection.

Observation:

• A 15-month-old boy was diagnosed with Kawasaki disease.
• The patient subsequently developed varicella 7 days after Kawasaki disease onset.
• Diffuse plaque psoriasis appeared 43 days after the initial Kawasaki disease diagnosis.

Findings:

• This case presents a rare triple association: Kawasaki disease, varicella, and psoriasis.
• Individual associations between these conditions have been previously documented.
• The co-occurrence of all three is exceptionally uncommon in medical literature.

Implications:

• Increased awareness of these rare triple associations is needed among healthcare providers.
• Further research may elucidate potential pathogenetic links between these conditions.
• Recognizing these combined presentations is crucial for comprehensive patient management.
