Out of 50 patients there were 32 (64%) females (housewives 36%) patients and 18 (36%) male (farmers 12%). Itching was the most common presenting symptom in 39 patients (78%) least was hypopigmentation and pain in 2%. Forehead was the most common site of involvement in 25 patients (50%) least were cheeks in 15 patients (30%). Erythema was the commonest morphological presentation seen in 36 patients (72%).
