Foot odor is found on the feet and can be unilateral or bilateral. 2. The rash can appear as small, uniform, deep blisters, some of which can become scaly and crusty after they have broken and dried. The foot has a variety of manifestations such as blistering, macerated vesicles and keratinized chaps. 3, laboratory tests, if the foot can see the presence of fungal hyphae and spores under the microscope, the fungal microscopy of herpes perfringens is negative. 4, treatment, herpes perfringens can be applied glucocorticoid drugs, such as dinaide ointment. Foot fungus requires the application of antifungal drugs, such as clotrimazole ointment.
