BACKGROUND: Textile allergy is a well-established entity, but there are relatively few Australian reports in this area. OBJECTIVES: To report the combined experience of textile contact dermatitis from the general and occupational contact dermatitis clinics at the Skin and Cancer Foundation, Melbourne, Victoria, Australia. PATIENTS/ METHODS: On the basis of the clinical suspicion of textile allergy, 2069 patients were tested with a textile series. RESULTS: One hundred and fifty-seven (7.6%) patients reacted to any of the textile-related allergens. The most common allergen was Basic Red 46 (20.2% of the positive reactions), followed by Disperse Blue 106 and Disperse Blue 124 (11.8% and 11.2%, respectively). Reactions to formaldehyde and formaldehyde-releasing chemicals accounted for 30.6% of the concomitant reactions, and reactions to p-phenylenediamine accounted for 12.6% of the concomitant reactions. The use of Disperse Blue mix yielded only 12.2% of patients sensitive to either of these two allergens, and it is not endorsed as a screening agent for textile dye allergy. CONCLUSION: Textile allergy is not uncommon. In Melbourne, Basic Red 46 in inexpensive, dark-coloured, acrylic-blend, men's work socks is the most important cause. It is important to test with samples of patients' clothing.
