Not Every Itchy or Ring-Shaped Rash Is a Fungal Infection
Itching, redness, scaling, or a ring-shaped rash can have several different causes. Fungal infections can sometimes look similar to eczema, dermatitis, psoriasis, and other skin conditions. A proper clinical assessment can help determine whether a rash is caused by a fungal infection or another condition.
Avoid starting medication based only on the appearance of a rash, particularly if the condition is recurrent or not improving with treatment.
How Are Fungal Skin Infections Diagnosed?
A dermatologist may be able to identify a fungal infection from the appearance and location of the affected skin. However, fungal infections can sometimes resemble other skin conditions.Depending on the location and appearance of the rash, additional testing may be recommended. This can include examining a sample of skin, hair, or nail material to help confirm the diagnosis.
Treatment depends on the type of fungal infection, the area affected, the extent of the infection, and the patient's individual circumstances.
Be Careful With Steroid Creams for Suspected Fungal Infections
If you suspect that you have a fungal infection, avoid using steroid creams or steroid-antifungal combination creams without medical advice. Steroids can make some fungal infections worse and may change the appearance of the rash, making diagnosis more difficult.If a rash is persistent, spreading, or repeatedly returning, seek advice from a dermatologist rather than continuing to self-treat.
Why Do Fungal Infections Keep Coming Back?
A fungal infection may recur for several reasons, including incomplete treatment, continued exposure to a source of infection, persistent moisture, reinfection from another person or animal, or an incorrect initial diagnosis.If a rash repeatedly returns despite treatment, it is worth having the diagnosis reassessed rather than repeatedly using the same medication.
