Of the 81 patients with PD, the males constituted 54% (44) and the mean age was 22 years (range: 1-51 years). The commonly affected groups were those aged 11-20 years (40.7%) and school or college students (50.6%). The common symptoms were pain, itching, redness, tenderness and blister formation. The lesions were erythematovesicular (70%), linear (54.3%) and kissing lesions (28.4%). All patients received some form of topical or oral steroid therapy and recovery was 100%. The mean duration from the onset till the recovery of the skin rash was 13 days (SD ± 8.3 days). PD outbreak is a self-limiting form of contact dermatitis.
