Fungal infections of the skin may cause white patches, which may also appear as skin flaking and erythema; and white patches of the skin may also be caused by other reasons, such as vitiligo, pityriasis alba, and hypopigmentation of the skin. Skin diseases caused by fungal infections are commonly caused by fungi such as Malassezia and Trichophyton rubrum. Infection of the skin may result in localized scaly, circular red patches or white patches covered with fine scales and may be accompanied by mild or marked itching, leaving hypopigmented patches. The lesions may appear on several parts of the body, such as the trunk and extremities. The appearance of white patches on the skin can also be caused by a variety of other diseases, such as vitiligo, pityriasis alba, anaplastic nevus, anemia nevus, hypopigmentation of the skin, sclerosing atrophic moss, follicular white patches of tuberous sclerosis, idiopathic punctate white patches, and so on. It is recommended that people with symptoms should consult a doctor in time and have a relevant examination to clarify the cause of the disease.
