The main difference between tinea capitis and ringworm is a positive fungal test for tinea capitis. From a clinical point of view, tinea capitis mainly affects the hands, and the lesions appear as small, dense blisters on the sides and tips of the fingers, accompanied by an itching or burning sensation. Tinea capitis, also known as ringworm, is an infection of the palm of the hand with ringworm. It begins as a pinhead-sized blister with thick, shiny walls and clear fluid. The blisters are usually itchy. After the blisters dry, there will be flaking and gradually spread around the expansion, forming a ring or multi-ring-shaped damage, the edge is relatively clear. From the above clinical manifestations and the fungal reexamination, it is clear whether it is lichen planus or tinea capitis.
