or mycoses
Diseases caused by any fungus that invades the tissues.
Superficial fungal infections (e.g., athlete's foot) are confined to the skin. Subcutaneous infections, which extend into tissues and sometimes adjacent structures such as bone and organs, are rare and often chronic. In systemic infections, fungi spread through the body of a normal (or, more often, an immunosuppressed) host. Some fungal diseases (e.g., yeast infections) may be either superficial or systemic, affecting certain target organs.
