What is the correct term for a fungal infection of the skin on the trunk or limbs?

The term "tinea corporis" refers specifically to a fungal infection that affects the skin on the trunk and limbs. This condition is commonly known as ringworm, despite not being caused by a worm. It is characterized by red, circular patches with clearer centers, and it can appear on various areas of the body, including the arms, legs, and torso.

Each of the other terms refers to different types of fungal infections affecting specific areas of the body. For instance, "tinea pedis" refers to athlete's foot, which is a fungal infection that occurs between the toes and on the feet. "Tinea capitis" is associated with the scalp, leading to hair loss and other symptoms. "Tinea cruris," also known as jock itch, occurs in the groin area. Thus, understanding the specific terminology for different types of fungal infections helps in accurate diagnosis and treatment in cosmetology and related fields.
