Mucormycosis is a fungal infection of the sinuses, brain, or lungs. It occurs in some people with a weakened immune system.
Fungal infection - mucormycosis
Mucormycosis is caused by different kinds of fungi that are often found in decaying organic matter. These include spoiled bread, fruit, and vegetables, as well as soil and compost piles. Most people come in contact with the fungus at some time.
However, people with a weakened immune system are more likely to develop mucormycosis. These include people with any of the following conditions:
Mucormycosis may involve:
Symptoms of rhinocerebral mucormycosis include:
Symptoms of lung (pulmonary) mucormycosis include:
Symptoms of gastrointestinal mucormycosis include:
Symptoms of kidney (renal) mucormycosis include:
Symptoms of skin (cutaneous) mucormycosis include a single, painful, hardened area of skin that may have a blackened center.
Exams and Tests
Your health care provider will examine you. See an ear-nose-throat (ENT) doctor if you are having sinus problems.
Testing depends on your symptoms, but may include these imaging tests:
A biopsy must be done to diagnose mucormycosis. A biopsy is the removal of a small piece of tissue for laboratory examination to identify the fungus.
Surgery should be done right away to remove all dead and infected tissue. Surgery can lead to disfiguration because it may involve removal of the palate, parts of the nose, or parts of the eye. But, without such aggressive surgery, chances of survival are greatly decreased.
You will also receive antifungal medicine, usually amphotericin B, through a vein. After the infection is under control, you may be switched to a different medicine.
Mucormycosis has a very high extremely high death rate, even when aggressive surgery is done. Risk of death depends on the area of the body involved and your overall health.
These complications may occur:
When to Contact a Medical Professional
People with weakened immune systems and immune disorders (including diabetes) should seek medical attention if they develop:
Because the fungi that cause mucormycosis are widespread, the best way to prevent this infection is to improve control of the illnesses associated with mucormycosis.
