To the editor, Olaquindox is an allergen and photoallergen specifically affecting pig breeders. Only a few cases of allergic and photoallergic contact dermatitis have been reported since 1985 (1–5). We report a new case which stresses the importance of Olaquindox as an allergen and photoallergen capable of inducing prolonged photosensitivity. A 53-year-old man presented in March 1999 with a photodistributed eczema on the face (sparing eyelids), neck and backs of the hands and fingers. He had been taking Rilmenidine (HyperiumA) and Diltiazem (MonotildiemA) for 4 years, Pravastatin (ElisorA) for 1 year withdrawn in March 1999. The patient was atopic. He had also worked as a pig breeder for 10 years and used azaperone (StresnilA), a sedative drug for pigs, oxytetracycline (DuphacyclineA) and Olaquindox, an antibiotic molecule which is added to the pigs food to avoid enteritis at the time of weaning. Olaquindox was included in a vitamin and mineral complex presented in powder form. The photobiological testing was performed with two sources of light: polychromatic irradiation (UVB, UVA, visible)
