An armpit fungus is a ringworm infection which occurs on the skin of the axilla (armpit) causing itching, burning and darkening of the skin under the arms. Similar to fungal infections on other areas of the body, an armpit fungus can be persistent given the high moisture content (due to armpit sweat), low light (covered by clothing) and warmth (due to body heat).

What Causes an Armpit Fungus?

An armpit fungus is caused by skin fungi,  usually skin molds or dermatophytes, that consume the superficial layers of the skin. Medically, a skin mold is referred to as a tinea infection and a fungal infection of the armpit is known as tinea axillaris. However most armpit fungal infections may extend beyond just the area of the armpit to surrounding skin and it is common to refer to the infection as tinea corporis (fungal infection on the body) involving the axillae. A skin yeast or cutaneous candidiasis may also be responsible.

Athlete’s Foot (Tinea Pedis, Ringworm of the Foot)

Athlete’s foot refers to infection of the foot by different fungi commonly called Tinea pedis. Skin between toes, on soles, and sometimes on sides or upper part of the foot is usually itchy, sore, reddened, damp, and may peel off and crack (Picture 1). The condition mostly affects people who constantly have wet feet due to occupation, humid environment, or wearing shoes with poor ventilation. Athlete’s foot is common in athletes but anyone can get it. One can contract Tinea pedis from public shower or gym floor, or by sharing contaminated shoes.
