A 5-year-old with a Hand Burn

The mother reports the child spilled hot liquid while removing a cup from the microwave. Does the injury match the claim?

A 5 y/o boy is seen for a hand burn, 9 days post-injury. He was treated in the ED after scalding water spilled on the back of his hand. Silver sulfadiazine was prescribed. Initial blister burst within 1 day of burn. Pain now managable.

     

How severe is this burn? Was this an accident?
