Neither are common, and the subcutaneous mycoses, with some exceptions, are largely confined to the tropics and subtropics. In recent years, the systemic mycoses have become important opportunistic infectious complications in immunocompromised patients, including those with AIDS and patients receiving treatment for malignancies. They also include a group of primary respiratory tract infections, such as histoplasmosis and coccidioidomycosis, which may affect otherwise healthy individuals and those with underlying illness. The fungi that cause these respiratory tract infections are usually dimorphic or exist in a different morphologic phase (eg, yeast or mold) at different stages of their life cycle.
