Mycetoma caused by Nocardia asteroides.

During the last 5 years six cases of mycetoma have been referred to the Razi Hospital, Thehran. Nocardia Asteroides was found to be the causative agent in one case only. Five of the patients were males, all being rice farmers, and one was a female. All of them belonged to Northern Iran which has a mediterranean climate. Treatment of the condition still remains unsatisfactory and ineffective and amputation may have to be performed as a last resort.
