Creeping Eruption

Alternate Names

  • cutaneous larvae migrans

Definition

Creeping eruption is a hookworm infection of the skin. The skin is invaded by the larvae of the dog or cat hookworm. This causes a thread-like line of inflammation that moves in a "creeping" form over time.

What is going on in the body?

Creeping eruption occurs when human skin comes into contact with soil contaminated with cat or dog feces that are infected with hookworm. The eggs of the hookworm are passed in the feces, and hatch into larvae. The larvae penetrate human skin and begin to wander through the layer below the skin.

Risks

What are the causes and risks of the condition?

Creeping eruption usually affects a person who plays or works in shaded, moist, sandy areas that have been contaminated with animal feces. Children and farmers are at greatest risk. It is more common in warm, humid areas, including the southeastern United States.

Prevention

What can be done to prevent the condition?

Prevention requires awareness of the hookworm parasite, keeping beaches and sandboxes clean, and proper disposal of cat and dog feces.

Diagnosed

How is the condition diagnosed?

The characteristic lesions strongly suggest creeping eruption. The person has usually had contact with warm, moist soil within the past few months.

Long Term Effects

What are the long-term effects of the condition?

There are no long-term effects from creeping eruption.

Other Risks

What are the risks to others?

There are no risks to others, as creeping eruption is not contagious from person to person.

Treatments

What are the treatments for the condition?

The treatment of creeping eruption includes thiabendazole (i.e., Mentezol). This medication can be taken by mouth, or applied topically to the rash. Cool, moist cloths applied to the rash can help relieve itching.

Side Effects

What are the side effects of the treatments?

Side effects of thiabendazole include nausea, vomiting, abdominal distress, and dizziness.

After Treatment

What happens after treatment for the condition?

Creeping eruption usually clears up in 1 to 2 weeks. The rash should clear completely with treatment.

Monitor

How is the condition monitored?

The healthcare professional should be contacted if the rash does not clear up completely, or if it returns.
