[Focal epithelial hyperplasia in lepromatous leprosy].

Focal epithelial hyperplasia Heck (FEH) is most likely caused by human papilloma virus. It mainly occurs in children and young people showing no associated diseases. For the first time, we describe a case of FEH in a patient with lepromatous leprosy who due to persistent erythema nodosum leprosum has been treated with a lang-term glucocorticoid therapy. The question of the competence of lepromatous patients in resisting certain viral infections arises.
