An active case search method was used, covering a population of 14,653 students, in 53 schools within the municipal network. Clinical examination gave rise to a leprosy diagnosis for 20 students, which represents a detection coefficient of 13.6/10,000 students. Cutaneous lymph bacilloscopy was performed on all cases, and it was positive in two samples. The predominant clinical form was the indeterminate form, with 12 cases (60%), followed by the tuberculoid form, with five (25%) and the dimorphous form with two (10%). Biopsies were then taken from the lesions of 11 patients, and histopathological analysis showed common findings of hyperkeratosis, mononuclear inflammatory infiltrate and ectasia of vessels and isolated arrector pili muscles. The study also enabled identification of some other infectious skin diseases: pityriasis versicolor in 793, scabies in 361 and dermatophytosis in 119. A variety of nonspecific conditions were also detected, such as scars, nevi and excoriation, in 1,020 students.</p>  a0037-8682
