Health professionals refer 10 fungal skin diseases as “tineas” and name them according to the region affected (TABLE 23.1). Fungal skin diseases are persistent, in part because fungi can penetrate deeper layers of skin than can ointments and creams. There are fewer antifungal drugs than antibacterial ones, and antifungals often have more severe side effects. Reflect on the evolutionary relationships among bacteria, fungi, and humans. Why it is harder to fight fungi than bacteria?
TABLE 23.1
Fungal Diseases of Skin | |

Tinea corporis (ringworm) | Trunk, limbs |
Tinea pedis (athlete’s foot) | Feet, toes |
Tinea capitis | Scalp, eyebrows, eyelashes |
Tinea cruris (jock, itch) | Groin, perianal area |
Tinea barbae | Bearded areas |
Tinea unguium | Toenails, fingernails |
