The outlook for rash depends on the underlying cause. The prognosis of clearing a superficial fungal infection is very good while a patient with psoriasis or eczema may not clear completely despite aggressive therapy. Most rashes are short-lived and easily resolve. There are some chronic rashes that are not curable, such as psoriasis. Medical monitoring is often necessary to watch the progression of more resistant or recurrent rashes. Any persistent rashes or rashes that are refractory to appropriate treatment may warrant a skin biopsy to rule out cancer.
