Tinea corporis does not have the simplest method of identification, which is generally based on the site of occurrence as well as the typical clinical presentation. It can also be identified by positive fungal microscopy or culture isolation of dermatophytes. Tinea corporis refers to dermatophyte infections occurring in superficial areas other than the scalp, hair, palmoplantar and nail plate. 1. Clinical manifestations: the primary damage is papule, blister or herpes mound, gradually expanding and spreading to the surrounding from the center, forming ring-shaped or multi-ring-shaped erythema and accompanied by flaking, the edge of which is slightly elevated, with obvious inflammation, while the central inflammation is mild or seems normal, accompanied by different degrees of itching. 2. Positive fungal microscopy: scrape the scales on the edge of the lesion for fungal microscopy. Positive manifestations are refractile, elongated, smooth, branching segregated hyphae and/or arthrospores. If you suffer from ringworm, please go to the hospital in time, complete the examination and make a clear diagnosis, and then carry out standardized treatment under the guidance of the doctor.
