What is tinea corporis commonly known as?

Tinea corporis is commonly known as ringworm due to its characteristic circular, red, ring-like appearance on the skin. The name “ringworm” is derived from the circular lesions that resemble a worm under the skin, although it is important to note that it is not caused by a worm; rather, it is a fungal infection. Tinea corporis can affect various parts of the body, presenting as itchy, scaly patches that may expand outward, clearly defining the ring-like shape.

The other options do not accurately represent tinea corporis: while a fungal rash may be a broad term that could include tinea, it lacks the specificity of the common name “ringworm.” Foot fungus refers specifically to tinea pedis, which affects the feet, and skin tags are harmless growths on the skin that have no relation to fungal infections. Understanding these distinctions helps clarify why “ringworm” is the most appropriate term for tinea corporis.
