We observed a 65 years old male patient with pruritus, scaling erythema and liquenification areas on the face, neck, forearms and hands. For six years he had a story of episodic crisis of exsudative erythema associated with farm work. The skin biopsy showed irregular acantosis with slight hyperkeratosis and a mild multifocal lymphohistiocytic infiltrate, with many eosinophils. The patch tests with the Contact Dermatitis Portuguese Group of Study standard tray were positive for colophony, perfume mix and lactone mix. The patch tests with plant series were positive to atranorin, usnic acid, alantolactone, Parthenolide, lichen mix, Frulania dilatata, Achillea millefolium and Tanacetum extracts. Treatment was started with oral prednisone and hydroxyzine plus topical hydrocortisone and emollient cream with great improvement. The patient was advised about the avoidance of possible allergens sources. This kind of multisensitization to plants is an uncommon finding and poses diagnostic and therapeutic problems. This patient had a sustained recovery by avoiding farm work and by removal of in house plants.
