Arthritis without grains caused by Pseudallescheria boydii

Abstract
Severe infection of the knee joint by Pseudallescheria boydii in a 23-year-old female resulted in complete destruction of the cartilaginous surface. The possibility of entry of the fungus through mild abrasions of unperforated skin is discussed. The clinical appearance is compared with that of Scedosporium prolificans. Antimycotic miconazole-itraconazole treatment, applied during a period of 4 months, was successful; no side-effects were noted.
