In the patient who is immunocompromised, disseminated disease with meningitis caused by C.neoformans is common.Disseminated cryptococcosis and cryptococcal meningitis became well recognized in patients with AIDS, and both infections remain important causes of morbidity and mortality in patients in resource-poor countries who do not have access to highly active antiretroviral therapy (HAART).Patients with disseminated infection may exhibit painless papular skin lesions that may ulcerate.Other less common manifestations of cryptococcosis include endocarditis, hepatitis, renal infection, and pleural effusion.
