When the pathogenic fungi invade the cuticle of the human body, they can cause mild inflammatory reaction, such as erythema, papules, blisters and other damage, followed by desquamation, often ring, so they are commonly known as tinea rotundum or tinea capitis. At the beginning, the damage is scattered separately. When it gradually expands, it can merge and overlap with each other, sometimes even to the whole body, In particular, some patients with immunodeficiency or the use of immunosuppressants, corticosteroids, anti-tumor drugs, skin lesions can be very extensive.
