Fungal Skin Infection
On this page:
Infection of the skin caused by a fungus. A variety of
micro-organisms like bacteria,
mold-like (dermatophytes or tinea), and yeast-like fungi (Candida) are
normally present on the skin. Some of these are useful to the body and are
known as good bugs. Others may, under proper conditions, multiply
rapidly and cause infections.

Fungal skin infections can be grouped as:
- Ringworm Infections - caused by a a mold-like fungus (dermatophytes)
called tinea. These fungi live on the dead tissues of the hair, nails and
outer skin layers. According to its location on the body, tinea infection
can be sub-divided into :
- Tinea pedis - ringworm infection on the feet (athlete's foot)
- Tinea capitis - ringworm infection of the scalp
- Tinea cruris - ringworm infection of the groin, also called jock itch
- Tinea corporis - ringworm infection of the skin
- Candida Infections - Cutaneous candidiasis
is an infection of the skin caused by the fungus Candida albicans. It may
involve almost any
skin surface on the body, but usually occurs in warm, moist areas
such as armpits and groins. Oral thrush is a form of candida infection
found on
the mucous membranes of the mouth and vaginal yeast infections are extremely
common candida infections.

- Blastomycosis - Blastomycosis is a fungal infection caused
by Blastomyces dermatitidis. The skin becomes infected as the fungus spreads
throughout the body. Skin lesions may be wart like or appear as ulcers and
may affect the nose and mouth. It is acquired by inhaling fungal particles
found in wood, moist soil, particularly amongst decaying vegetation. People
with compromised immune systems such as HIV infection or organ transplant
recipients are highly at risk for developing this infection.
- Histoplasmosis - Histoplasmosis is a fungal infection
caused by Histoplasma capsulatum. This fungus grows as a
mold in soil contaminated
with bird and bat droppings. The characteristic skin leisions of histoplasmosis
appear as lumps or nodules. Elderly people or those who have underlying
immune
disorders such as AIDS are at higher risk for histoplasmosis infection.
- Coccidioidomycosis - Coccidiodomycosis is a disease caused
by the spores of the fungus, Coccidioides immitis which is often found in
desert regions. Skin lesions of coccidioidomycosis are a manifestation in
the skin of this fungal infection. The characteristic skin lesions can occur
in the early stages of infection and appear either as ulcer, tender red papules,
nodules (erythema nodosum) or as a hypersensitivity allergic skin rash (erythema
multiforme). These rashes usually clear without treatment and are
believed to be caused by an immune response to the infection.
