Abstract
- Visceral larva migrans is a syndrome presented chronic peripheral eosinophilia, hepatomegaly with eosinophilic granuloma. Originally it results from migration of second stage larva of Toxocara species, animal ascarides, but there are many other causative parasites. It's difficult to detect causative parasite, although immunohistochemical methods like ELISA or Ouchterlony method have been introduced. If the larva were dectected, it's not easy to discriminate causative one from others because of similarities of morphology. Most cases have self-limited course. Only in severe infection, antiparasitic treatment, augmented by corticosteroid when allergic symptopms are also present, is required. Clinical presentations have varieties of spectrum, hepatomegaly with eosinophilic granuloma is most common. Some cases of pulmonary, ocular and CNS symptoms were reported. We now report a case of visceral larva migrans, presented submucosal tumor or diverticulitis in the ascending colon and went through laparoscopic right hemicolectomy. The diagnosis was made with microscopic examination of operation tissue.
