This study was an open prospective study reporting the results of patch test data from a dermatology clinic at a tertiary care hospital in Jaipur, Rajasthan (India) from October 2012 to April 2014. Hundred patients (59 males and 41 females) with contact allergic dermatitis of hands were tested with standard series of 24 allergens consisting of Indian standard series of patch testing, expanded with allergens prepared from extracts of onion, garlic, soap and detergents. Occupationally the patients included were unskilled workers (53%), housewives (19%), skilled workers (10%), students and people engaged in white-collar jobs - 9%. The frequent sensitizers were found to be potassium dichromate (28%), nickel sulphate (25%), vegetable (10%), medicaments (7%), parthenium (6%), soap and detergents (5%), fragrance mix (4%), and paraben mix (3%). In majority of the patients, occupational substances were the causative allergens leading to contact dermatitis.
