    Most probably the nematode Ancylostoma braziliense in its third larval stage. It is the most common hook worm in the area. Checks out with dogs, moist sand in warm weather as in Puerto Rico, possible bare feet in a recreation area, and serpiginous lines or “creeping eruptions” wich are simptoms in human skin. Eosinophilia is seen in parasitic infections. It seems A.caninum is less frequent, as is Uncinaria stenocephala.
