Primary cutaneous nocardiosis is a rare disease. It is observed in people in contact with soil, after trauma. It is produced by an aerobic actinomyces which is found on the ground. We present a case of localized Nocardiosis placed on the left anatomical snuffbox. The patient was a 52 year old farmer. At the time of first consultation, the three year old lesions appeared as plaques which showed crusts and numerous suppurative fistulae, together with non painful nodules. He had no regional adenopathies. Material was taken for mycological direct and culture exams. A biopsy was taken for Anatomopathology. The patient remembered having suffered a trauma on the left hand by his tools in harvest time.
