Allescheria (Petriellidium) boydii sinusitis in a compromised host.

The first case of Allescheria (Petriellidium) boydii sinusitis is reported. The organism was isolated from the maxillary sinus in an elderly, diabetic, chronic alcoholic man on maintenance hemodialysis who developed a syndrome resembling mucormycosis. Infections with A. boydii are infrequent and are most commonly limited to Madura foot. In addition, several cases of pulmonary and central nervous system involvement have been described. There is no established therapy for A. boydii, since the published data on antimicrobial sensitivity are limited. Our organism was inhibited by 1.25 mg of amphotericin B per ml and 0.15 mg of miconazide per ml.
