Candidal infections are most commonly caused by the yeast Candida albicans. They are seen in warm, moist areas such as in the diaper area of children or in skin folds.

What does it look like?

Cutaneous candidal infections are generally beefy red in color with satellite lesions that are pustulovesicular. Candida can also be seen in the mouth where it is known as thrush. This causes curd-like white plaques on the oral mucosa and tongue that can be scraped off with a tongue depressor. When located in the corners of the mouth, candida can cause perlèche (also known as angular cheilitis). This condition is associated with maceration and lip licking and causes the corners of the mouth to become erythematous and crack.

How is it diagnosed?

The diagnosis is clinical and can be suspected when bright-red plaques with satellite lesions are seen in intertriginous areas.

How is it treated?

Topical antifungals, such as miconazole or clotrimazole, are useful in the treatment of candidiasis but must be used twice a day in order to clear the infection.
