Laboratory Studies
- The diagnosis of cutaneous larva migrans (CLM) is mostly based on the classic clinical appearance of the eruption.
- A minority of patients demonstrate peripheral eosinophilia on a CBC count and increased immunoglobulin E (IgE) levels on total serum immunoglobulin determinations.
Procedures
- A skin biopsy sample in cutaneous larva migrans, taken just ahead of the leading edge of a tract, may show a larva (periodic acid-Schiff positive) in a suprabasalar burrow, basal layer tracts, spongiosis with intraepidermal vesicles, necrotic keratinocytes, and an epidermal and upper dermal chronic inflammatory infiltrate with many eosinophils.
