Differential Diagnosis of Migratory Cutaneous Lesions with Eosinophilia

 

Patient selection:

(1) migratory, serpiginous skin lesions

(2) eosinophilia in the peripheral blood

 

Differential diagnosis:

(1) cutaneous larva migrans (associated with dog or cat hookworms)

(2) migratory myiasis

(3) gnathostomiasis

(4) sparaganosis

 

Migratory myiasis vs cutaneous larva migrans:

(1) Cutaneous larva migrans moves faster and is more extensive.

(2) The larvae in migratory myiasis are larger and can be visualized through the skin.

(3) The larvae of migratory myiasis may be present for a longer period of time (months).
