ABSTRACT
Numerosas especies de plantas y sus derivados pueden causar reacciones cutáneas por diversos mecanismos: dermatitis irritativa de contacto, dermatitis alérgica de contacto, urticaria de contacto y fotodermatitis. Se presenta un caso de dermatitis irritativa de contacto tras la exposición a la savia de Agave americana. Representa un cuadro cutáneo descrito en escasas ocasiones y que, aunque habitualmente se presenta como una erupción papulovesiculosa, en el paciente descrito aparece con lesiones purpúricas en la zona de contacto
