Actinomycetoma caused by Nocardiopsis dassonvillei

• We report a case of mycetoma caused byNocardiopsis dassonvilleiin a 39-year-old man. He had multiple nodules and draining sinuses on the anterior aspect of his right leg just below the knee. Few cream-colored granules were seen in the exudate. The biopsy specimen showed gram-positive, non-acid-fast granules with distinct borders. An aerobic actinomycete isolated from the lesion was identified asN dassonvillei. We think that this is the first reported case of mycetoma caused byN dassonvillei. (Arch Dermatol1985;121:1332-1334)
