An early case of mycetoma caused by a Nocardia species is described. The lesion, which appeared on the nose, clinically resembled granuloma faciale. Response to oral sulfonamide therapy was prompt and complete. It is emphasized that an initially pustular or crusted lesion evolving into a lesion clinically resembling granuloma faciale should be carefully studied mycologically, since effective therapy of mycetomas is dependent on early and accurate diagnosis.
