Key features

ย„Cutaneous fungal infections are broadly divided into two groups:

(1) those that are limited to the stratum corneum, hair, and nails; and (2) those that involve the dermis and subcutaneous tissues

ย„Superficial fungal infections of the skin are most often due to dermatophytes and Candida spp.

ย„โ€œSubcutaneousโ€ mycoses are often the result of implantation, while systemic or โ€œdeepโ€ mycoses of the skin usually represent hematogenous spread or extension from underlying structures

ย„In the immunocompromised host, opportunistic fungi, e.g.

Aspergillus and Mucor spp., can lead to both cutaneous and systemic infections

This chapter reviews common cutaneous fungal infections, and they are subdivided into three major groups: (1) โ€œsuperficialโ€; (2) โ€œsubcutaneousโ€; and (3) โ€œdeepโ€ or systemic (Table 77.1).
