Oral thrush. Tongue of a 74 year old woman with oral candidiasis (thrush, white patches). The patient is seen to have had a previous hemiglossectomy (surgical removal of one half of the tongue), which was to treat carcinoma (cancer) of the tongue. Candidiasis is an infection caused by the single-celled fungus Candida albicans. The fungus is commonly found on the skin and the mucous membranes of the mouth, digestive and respiratory tracts and the vagina, where it is usually harmless. However, the use of antibiotics or a suppressed immune system can lead to infection. Treatment is with anti-fungal drugs.
