Paecilomycosis in a nonhuman primate (Macaca mulatta)

Focal granulomas caused by fungi in the genus Paecilomyces occurred at subcutaneous and laryngeal sites in a Rhesus monkey. Slight wheezing was noted 8 months before the monkey died. Death was unexpected and was caused by asphyxiation after occlusion of the larynx by a fungal granuloma.
