Laboratory Studies

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

Skin biopsy is not usually helpful because the larvae are usually located several centimeters from the edge of the track.

A peripheral eosinophilia may be observed. [13]


Imaging Studies

A new technique, optical coherence tomography, has been found to identify the larvae in the epidermis, allowing direct removal. [14]
