Purpuric agave dermatitis☆☆★★

Wilford Hall Medical Center, Lackland Air Force Base. San Antonio, Texas

Abstract 

Agave Americana is a low growing, thick, long-leaved, subtropical plant used for medicinal, commercial, and ornamental purposes. The plant’s sap contains calcium oxalate crystals, acrid oils, saponins, and other compounds. Despite these known irritants, Agave-induced irritant dermatitis has rarely been reported. Previous case reports have noted a papulovesicular eruption consistent with an irritant contact dermatitis. We report a case of Agave-induced purpura in an otherwise healthy patient. Histopathology was consistent with an evolving leukocytoclastic vasculitis. (J Am Acad Dermatol 1999;40:356-8.)
