mucocutaneous lymph node syndrome
Definition: a systemic vasculitis of unknown origin that occurs primarily in children under 8 years of age. Symptoms include a fever lasting more than 5 days; polymorphic rash; erythematous, dry, cracking lips; conjunctival injection; swelling of the hands and feet; irritability; adenopathy; and a perineal desquamative rash. Approximately 20% of untreated patients may develop coronary artery aneurysms. As the child recovers from the illness, thrombocytosis and peeling of the fingertips occur.
