A recrute with blisters on the cheek

: A 37-year-old recrute in the Royal Dutch Army developed blisters on the right cheek approximately 30 minutes after a boot camp exercise in the mangroves of the island of Curacao. This bullous dermatitis was caused by direct contact with sap from the bark of the manzanilla tree (Hippomane mancinella). As a member of the family Euphorbiaceae, all parts of this tree are highly toxic. Even rain drops falling from the leaves can cause a bullous dermatitis. Usually, symptomatic treatment will allow healing of the dermatitis in a matter of weeks.
