[Distribution of Langerhans cells in the skin of patients with Hansen's disease].

Intra-epidermal OKT+ and OKla+ cells were identified and counted in 25 cases of Leprosy (7 lepromatous, 7 bordeline, 8 tuberculoid and 3 indeterminate). No significant variations were found in the number of Langerhans cells (OKT6+) in the clinical forms of the disease, nor marked variations were determined in the relation of OKT6+/OKla+ intra-epidermal cells. Nevertheless significant variation in the number of Langerhans cells were noted in several cases independently of the clinical form of the disease.
