A total number of sixty patients were assigned purposively. Among them thirty patients were belonged to Group A, treated with levamisole alone and another thirty patients belonged to Group B, treated with levamisole 160 mg weekly with topical 0.1% fluocinolone acetonide acetate on the lesions once a day for a duration of 6 months. Patients were followed up every 2 weeks interval and were continued up to 6 weeks. Out of all patients from group A, the mean sizes of the lesions were 8.17cm before treatment but 5.90cm, 4.32cm, and 3.57cm at 1st visit, 2nd visit and 3rd visit respectively after treatment.
