Cryptococcosis has emerged as an important public health problem in Africa, Asia and the Americas due to the increasing numbers of persons at risk of this infection and the adaptation of its aetiological agents to new environments. The proper management requires early recognition of Cryptococcus neoformans/C. gattii species complex infection, familiarity with the use and limitations of diagnostic tests and knowledge of the available treatment options. This review will address these issues with the goal of providing sufficient information to suspect, diagnose and treat patients with cryptococcosis based on Cuban data and review of the literature.

We describe pulmonary cryptococcosis in a 28-year-old previously healthy man. Exhaustive immunological investigations revealed a primary NK cell deficiency associated with a secondary impaired anti-Cryptococcus CD8 lymphocyte response and the expansion of a CD8Vβ14 + T cell clone. This case illustrates the potential role of NK cells in immunity against Cryptococcus.

Cryptococcus gattii is a saprophytic basidiomycete that grows in the environment and can cause systemic cryptococcosis. Ocular cryptococcosis causes blindness and is commonly associated with central nervous system (CNS) infection. Toll-like receptor 9 (TLR9) can control cryptococcosis and another mycosis.

is a fungal pathogen that can cause lethal disease in immunocompromised patients. Immunocompetent host immune responses, such as formation of pulmonary granulomas, control the infection and prevent disseminated disease. Little is known about the immunological conditions establishing the latent infection granuloma in the lungs.

HIV infection frequently affects multiple systems, with hematological manifestations being the most prevalent. In some cases, cryptococcosis serves as the initial manifestation and a cause of infection involving HIV-positive patients. This case report describes a patient with thrombocytopenia who incidentally discovered infiltrating the bone marrow upon bone marrow smear examination, highlighting that examining bone marrow is essential in diagnosing pancytopenia resulting from opportunistic fungal infections like cryptococcosis, especially in individuals with compromised immune systems.

Cryptococcal meningitis is an alarming fungal infection that usually affects the meninges surrounding the brain and spinal cord. The causative organism is Cryptococcus neoformans. Although this infection can occur in normal individuals, it is more often seen in patients with human immunodeficiency virus/acquired immunodeficiency syndrome.
