Alternaria infection of the skin and joints. A report of two cases involving the hand.

Alternaria is a fungus that is usually saprophytic but occasionally causes skin infections. Involvement of other structures is exceedingly rare. We report two cases in which a joint was also affected. The possible precipitating role of intraarticular glucocorticoid therapy is discussed. Both patients achieved a full recovery after itraconazole therapy, given for 12 and seven months, respectively.
