Clothing dermatitis frequently goes unrecognized either because the clinical picture is mistaken for other disorders, such as seborrheic dermatitis, and pruritus, or because it is difficult to trace the causal agent.
Contact dermatitis to disperse dyes, especially to azo dyes, has been well known and the most frequent sources of sensitization to dyes are dresses, stockings, and trousers made of synthetic fabrics.
We described a case of hat band contact dermatitis due to disperse dyes, proven by a patch test. although chrome was not proven by the diphenylcarbazide method, many dyes known to be contact allergens were proved in different kinds of hat bands.
