RESUMO
Mycetoma or Madura foot is a chronic infection of the foot characterized by swelling and multiple sinuses. The sinuses discharge pus composed of colored granules which contain the infecting organism. Although this entity is still rare in the United States, an increasing immigrant population and rapid air transportation have resulted in a greater number of cases being reported. A case of Madura foot is presented in which initial cultures yielded Staphylococcus aureus. Dicloxacillin was prescribed and this led to some improvement in the condition. Later, a gram-stained specimen of exudate from an inguinal site showed actinomycetes. Because of this finding, amoxicillin was then administered. As a result, the condition dramatically improved with subsequent healing of the involved bone.
