RESULTS: Various morphological pattern observed in our study was fissured pattern (43%), hyperkeratotic (12%), lichenoid (10%), pompholyx (4%), fingertip eczema (1%), ring pattern (1%) and mixed morphology (6%). Potassium dichromate was the commonest sensitizer observed in our Study (18.9%), followed by paraphenylenediamine (6.75%). In our study, current relevance was 79%, doubtful was 15%. CONCLUSION: Fissured pattern was the most common pattern noted in our study. Potassium dichromate was the commonest sensitizer observed in our study.
