While in Mexico a 34-year-old woman injured her left foot with a cactus. This resulted in the development of black grain maduromycosis due to Madurella grisea. Prolonged griseofulvin therapy had no effect on this condition. This is believed to be the fifth case of maduromycosis from M grisea seen in the United States and probably the first instance of maduromycosis from this fungus contracted in Mexico.
