A case of visceral larva migrans manifesting as arthralgia, edema of t
he limbs, and increased peripheral eosinophil counts is reported. Seve
ral diagnostic hypotheses are discussed. A remission was achieved unde
r fluoromebendazole and low-dose corticosteroid therapy. Two relapses
occured, after 17 and 29 months, respectively. This course may have be
en due to persistent Toxocara infection or to development of a self-su
staining rheumatic disease.
