Approach Considerations

Diagnosis of cutaneous larva migrans (CLM) is based on the physical examination and history.

Skin biopsy is not usually helpful because the larvae are typically located ahead of the tract.

Tissue specimens may show an inflammatory infiltrate made of eosinophils. The parasite itself is usually not visualized.
