[Foot mycetoma of double etiology].

A patient coming from an area of dry tropical forest was studied. This patient had in his right foot two tumor-like growths localized, one in the anterior and superior part of the foot, the other near the malleoli. From the first tumor, light-colored grains were obtained, and Actinomadura madurae was cultured. From the tumor near the malleoli only black grains were isolated from which a Pyrenochaeta sp. was cultured.
