What is the Difference Between Cutaneous and Subcutaneous Mycoses?

🆚 Go to Comparative Table 🆚

The main difference between cutaneous and subcutaneous mycoses lies in the depth of the infection in the skin.

  • Cutaneous mycoses are superficial infections that affect the epidermis, hair, and nails, generally causing little or no inflammation. Common cutaneous mycoses include tineas caused by dermatophytes of the genera Trichophyton, Epidermophyton, and Microsporum. Examples of cutaneous mycoses are tinea capitis, tinea corporis (ringworm), tinea cruris (jock itch), and tinea pedis (athlete's foot).
  • Subcutaneous mycoses penetrate deeper into the skin, infecting the dermis and underlying tissues. These infections usually result from a cut or puncture wound to the skin and can spread from the skin to deeper tissues. Sporotrichosis, chromoblastomycosis, and mycetoma are examples of subcutaneous mycoses.

In summary, cutaneous mycoses are superficial infections affecting the surface layers of the skin, hair, and nails, while subcutaneous mycoses are deeper infections that affect the dermis and underlying tissues.

Comparative Table: Cutaneous vs Subcutaneous Mycoses

Cutaneous and subcutaneous mycoses are fungal infections that affect different layers of the skin and underlying tissues. Here is a table summarizing the differences between the two:

Feature Cutaneous Mycoses Subcutaneous Mycoses
Definition Superficial fungal infections affecting the skin, hair, and nails Localized infections of the skin and underlying tissue
Inflammation May cause skin redness and inflammation Less inflammation than cutaneous mycoses
Causative Organisms Dermatophytes (Trichophyton, Epidermophyton, and Microsporum), yeasts (Candida) and other non-dermatophytic fungi Various fungi, including dematiaceous fungi and filamentous fungi
Treatment Antifungal medications Antifungal medications, surgical intervention in some cases
Prevention Good hygiene and proper wound care Proper wound care and avoiding exposure to fungi

Examples of cutaneous mycoses include tineas (ringworm) caused by dermatophytes and cutaneous candidiasis. Subcutaneous mycoses can involve chromoblastomycosis, mycetoma, and sporotrichosis.
