ABSTRACT
Four cases of human dermatophilosis observed in Rio de Janeiro, Brazil, are reported. Data that suggest nail infection by Dermatophilus congolensis are presented. The clinical spectrum of the disease ranged from an asymptomatic infection to a pustular eruption. Our findings suggest that epidermal Langerhans cells play a role in the pathogenesis of the infection.

An extensive and severe actinomycetoma by Nocardia asteroides, a rare etiologic agent of this infection in Brazil, observed during a 9 year follow-up is reported. Unsuitable social and financial conditions led to amputation as the only possible solution for this case, no signs of infection relapse having been observed in three years after his surgery.
