Background and purpose: 

Cytology, both exfoliative and aspiration cytology, may play a role in the detection of causative microorganisms in immune-competent and -compromized patients. Cryptococcus neoformans (C. neoformans), an environmental fungus, is an emerging opportunistic pathogen that causes focal or disseminated infection. Risk factors for cryptococcal infection include corticosteroid use, neoplasm, stem cell and solid organ transplantation, liver cirrhosis, chronic kidney disease, diabetes mellitus, rheumatologic disease, and infection with HIV.
