The writer has discovered in Curupaity (National Leprosarium, Rio de Janeiro), three cases of verrucous dermatitis in C 3 type lepers. He suspected it to be an association of leprosy with Dermatilis verrucosa blastomycetica (Chromoblastocycosis) but various attempts to cultivate the fungus (Acrotheca or Hormodendrum Pedrosoi) responsible for the disease gave negative results and also the histopathologic aspect of the verrucous tissue proved it to be a leprotic granuloma without mycotic association. The writer's conclusion, based upon the cultural and histopathological studies, is that the verrucous dermatitis observed is due to leprosy alone, considering it as a new syndrome of the disease and not a new clinical form. He has called it « Dermatitis verrucosa leprotica » and made suggestions to all doctors of leprosaria to look for new cases and to study their etiology and pathogeny. Electrocoagulation improved the lesions.
