An overview of pulmonary fungal infections

An overview of important pulmonary mycoses is presented. Four endemic mycoses occur in restricted geographic areas: histoplasmosis, blastomycosis, coccidioidomycosis, and paracoccidioidomycosis. Three opportunistic mycoses have causative agents that are ubiquitous in nature but cause infection only in compromised hosts: aspergillosis, mucormycosis, and candidiasis. Cryptococcosis is acquired by inhalation but usually presents as a chronic meningitis. Pulmonary sporotrichosis is rare; the usual subcutaneous form of the disease is acquired by inoculation. The clinical features of these infections are discussed, with special emphasis on recent advances in diagnosis and treatment.
