RESUMEN
We describe a patient with mycetoma or Madura foot, in which histopathological stains of the bone and surface cultures suggested three different organisms including Nocardia species as the cause. Criteria for the diagnosis of the organisms, differentiation between colonizer and pathogen, and significance of mixed infections are discussed.
Descrevemos um paciente com micetoma ou maduromicose de pé, no que colorações histopatológicos de osso e de culturas superficiais sugeriram três organismos diferentes, incluindo espécies de Nocardia como causador. Os critérios de diagnóstico dos organismos, a diferenciação entre colonizador e patógeno, e a significância das infecções mistas são discutidos.

Nodular granulomatous perifolliculitis is a well-recognized infection of the dermal and subcutaneous tissue caused by dermatophytes, which normally do not invade beyond the epidermis. We report here one such case that occurred in an immunosuppressed individual. The patient was a 35-year-old farmer who presented with small pruritic eruption that had initially appeared on the lower leg and then had gradually spread to hair-bearing areas of the body, finally producing nodular and pustular inflammatory lesions with exacerbations and remissions. Fungal examination by direct potassium hydroxide mount and culture revealed Trichophyton rubrum. Granulomatous changes were seen on histopathological examination. The patient completely responded to systemic antifungal therapy.

Neste trabalho, os autores estudam a localizaçäo de lesöes únicas de hanseníase, em 317 pacientes paucibacilares, registrados no ambulatório do CMS Jorge Saldanha e no Hospital Estadual de Curupaiti, ambos localizados em Jacarepaguá, Rio de Janeiro. A localizaçäo preferencial das lesöes, sua relaçäo com sexo e idade e os possíveis fatores de interferência nesta distribuiçäo na populaçäo estudada säo discutidos. Estes achados säo comparados com os resultados obtidos em pesquisas similares, realizadas por outros autores no contimente asiático e africano
