Predispositions to the superficial mycoses include warmth and moisture,
natural or iatrogenic immunosuppression, and perhaps some degree of
inherited susceptibility. Some of these infections elicit a greater
inflammatory response than others, and the noninflammatory ones are
generally more chronic. The immune system is involved in the defense
against these infections, and cell-mediated immunity appears to be
particularly important. The mechanisms involved in generating immunologic
reactions in the skin are complex, with epidermal Langerhans cells, other
dendritic cells, lymphocytes, microvascular endothelial cells, and the
keratinocytes themselves all participating in one way or another. A variety
of defects in the immunologic response to the superficial mycoses have been
described. In some cases the defect may be preexistent, whereas in others
the infection itself may interfere with protective cell-mediated immune
responses against the organisms. A number of different mechanisms may
underlie these immunologic defects and lead to the development of chronic
superficial fungal infection in individual patients. Although the
immunologic defects appear to be involved in the chronicity of certain
types of cutaneous fungal infections, treatment of these defects remains
experimental at the present time.
