Objective To study the various morphological patterns and to identify the exogenous allergens causing hand eczema(HE) with the use of Indian standard series of patch test.
Methods This was a cross-sectional prospective study conducted over a one year period from January 2018 to January 2019 and a total of 60 patients with hand eczema aged 18years and above were included. Patch tests were applied to upper back and readings were recorded after 48hours. Data were coded and analysed at the end of study.
Results Of the 60 patients, 37 (64%) were females and 23(36%) were males. About 28 (46.7%) of them were between age group of 41 to 60 years. House wives 14 (23.3%) were most commonly affected followed by farmers 13 (21.7%). The common morphological pattern seen was chronic scaly eczema in 18 patients (30%) followed by nummular eczema in 11 patients (18.3%). Atopic history was positive in 16 (26.6%) patients. Patch test was positive in 13 (22%) patients and most common allergen found was potassium dichromate.
Conclusion Potassium dichromate was the commonest sensitizer observed in our study especially among construction workers and labourers. Patch test played a pivotal role in identifying the triggering allergens and this in turn will be helpful for the patients in avoidance of allergens thereby significantly improving the quality of life.
