cryptococcosis

An acute, subacute, or chronic infection by Cryptococcus neoformans, causing a pulmonary, disseminated, or meningeal mycosis. The pulmonary form may resolve spontaneously in previously normal persons but dissemination to other organs is fatal if untreated; the most common clinical manifestation is meningitis.

n.
a disease of worldwide distribution, but recognized mainly in the USA, caused by the fungus Cryptococcus neoformans. The fungus attacks the lung, resulting in a tumour-like solid mass (toruloma), but produces few or no symptoms referable to the lungs. It may spread to the brain, leading to meningitis; this may occur as an opportunistic infection in those suffering from AIDS. The condition responds well to treatment with amphotericin.

cryp·to·coc·co·sis (krip″to-kŏ-koґsis) infection by Cryptococcus neoformans, Cryptococcus gattii, or rarely other Cryptococcus species, most commonly seen in immunocompromised patients. It begins with a pulmonary infection, which may be asymptomatic, following inhalation of the organism. Disseminated disease may occur and can affect most other organs, but it has a predilection for the brain and meninges, where it causes meningoencephalitis that ranges from subacute to chronic; skin involvement is characterized by an acneiform rash. Called also torulosis, European blastomycosis, and Buschke or Busse-Buschke disease.
