What does dermatomycosis signify?

Dermatomycosis signifies an infection of the skin caused by fungi. This term combines "dermato," which relates to the skin, and "mycosis," which refers to a fungal infection. Fungal infections of the skin can manifest in various ways, such as rashes, lesions, and irritation, and understanding this term is vital for identifying and treating such infections in a clinical setting.

The other choices refer to different medical conditions. Temporary inflammation of the skin describes a different type of response, often linked to irritants or allergies, rather than a fungal infection. A malignant skin tumor pertains to a cancerous growth, which is entirely distinct from a fungal infection. An allergic reaction on the skin references the body's immune response to allergens, resulting in conditions such as hives or eczema, also unrelated to fungal infections. Thus, the association of dermatomycosis with a fungal infection is what makes the first option correct.
