Maxillary sinus infection with Allescheria boydii (Petriellidium boydii)

Allescheria boydii (Petriellidium boydii) has previously been described as a cause of Madura foot and pulmonary and other visceral infections. This report describes infection of the maxillary sinus and facial soft tissue with A. boydii in a compromised host. The infection did not respond to antibiotics, including amphotericin B and 5-fluorocytosine. Miconazole was not used in our patient, although in vitro data obtained after death indicated sensitivity of the fungus to miconazole.
