|Description:||This image depicts a skin lesion in a case of a disseminated fungal infection, cryptococcosis, caused by a member of the fungal genus, Cryptococcus. Note the ovoid crusty, central region of the lesion, which is surrounded by a raised, erythematous border.|
Cryptococcosis is an infection caused by fungi that belong to the genus Cryptococcus. There are over 30 different species of Cryptococcus, but two species – Cryptococcus neoformans and Cryptococcus gattii – cause nearly all cryptococcal infections in humans and animals. Although many people who develop cryptococcosis have weakened immune systems, some are previously healthy.
