Mycetoma : Pseudallescheria boydii
Image Description
This photomicrograph of a PAS-stained tissue section from a patient with eumycotic mycetoma shows a granule surrounded by inflammatory infiltrate. The causative organism was Pseudallescheria boydii, an ascomycetous mold.
Pseudallescheria boydii is the most common etiologic pathogen associated with eumycetoma in the United States. The disease is a chronic cutaneous and subcutaneous infection with the foot being the most common site of infection. The fungal spores gain entry into subcutaneous tissues via small breaks in the skin resulting from repeated minor occupation-related trauma.
