[Histoid variety of lepromatous leprosy]

Three cases of the so-called "histoid variety" of lepromatous leprosy are reported. This variety has definite clinical features, associated with characteristic histological and bacteriological findings. Some of the features presented by our patients are similar to those described originally by Wade, especially the resistance to treatment. Considering the discrepancies existing among the authors that studied the subject, our opinion is that further studies should be done in order to elucidate the controverted points.
